Bontnewydd School to showcase reuse of materials in construction

by

The project embraces the “cascading” principle, which emphasises reusing materials with minimal reprocessing to preserve their value and reduce energy consumption.

Gwynedd Council’s (Cyngor Gwynedd) transformative Bontnewydd School project, part of the Minister’s Sustainable Schools Challenge. As part of this challenge, the Minister invited bids for innovative projects that demonstrated collaboration with local communities—including school pupils—in the design, delivery, and management of the schools. Initially, two winners were to be selected, but due to the high calibre of the submissions, the Minister approved funding for three new sustainable schools, with a total capital investment of £44.7 million across all three projects.

Bontnewydd School is one of the projects selected through this highly competitive process, and it has received nearly £12 million in investment from the Welsh Government to build an environmentally friendly school, including modern community facilities. (For more details, see Ysgol Bontnewydd).

Salvaging materials for a greener future

Woodknowledge Wales (WkW) and the Bontnewydd team are working exhaustively on exploring viable possibilities for the reuse and integration of reclaimed materials within the new design. The WkW Team has been particularly instrumental in evaluating the quality of timber components, to assess their potential for reuse in the new school. At the heart of this project is the commitment to integrating salvaged and recycled building materials into the design. Rather than demolishing neighbouring buildings, materials are being carefully decommissioned and deconstructed, with an emphasis on reclaiming as many reusable materials as possible for the new construction.

Woodknowledge Wales’ role in the project is to explore how valuable timber components can be salvaged and reused in the new Bontnewydd school.

“This project represents a fantastic opportunity to improve the construction sector in Wales, aiming to get closer to a genuine sustainable sector, by attaching value to our existing resources and maximising their use and service life. For the Bontnewydd project, valuable materials such as Victorian bricks, Welsh slate tiles, and structural timber, which would typically be thrown away, are being carefully salvaged and repurposed. This approach helps to significantly cut down on landfill waste and reduce the overall environmental impact of the construction,“ said Dr Diana Waldron, WkW’s lead on this project.

Cascading reuse: Maximising material value

In support of this initiative, Woodknowledge Wales brought together timber grading experts to assess the reclaimed timber elements. This process aims to gather evidence that can inform the process moving forward. Additionally, we facilitated discussions with specialists in timber-based building systems, including suspended timber floors. One of our key sessions focused on exploring viable ways to repurpose the reclaimed timber, in line with the concept of “cascading.” This approach encourages minimal reprocessing, with the aim of reusing materials in their current form where possible and reserving more complex repurposing for later stages.

In terms of structural timber, the ideal solution is to incorporate it directly into the timber frame design. However, we have also explored the possibility of using the reclaimed timber to produce Glulam (glue-laminated timber) within the UK. To assess the feasibility of this option, we invited experts in Glulam manufacturing to join the discussions. For timber that is unsuitable for structural use, we are also considering alternative design applications.

The challenges involved in these efforts should not be underestimated. The UK’s current construction infrastructure does not fully support the integration of salvaged materials, and most materials from demolition sites still end up in landfills. The complexity of carefully deconstructing materials without damaging them, coupled with challenges related to transport and storage, creates significant obstacles for clients and contractors. This often results in high costs for projects attempting to reuse materials. Additionally, timber, being more vulnerable to damage and moisture than other materials, requires extra care during extraction, transport, and storage, adding further complexities to the process.

Tackling embodied carbon: Reusing foundations

WkW’s sustainability efforts extend beyond timber. The organisation also works to reduce embodied carbon—the emissions associated with producing and transporting building materials. To support the Bontnewydd project, WkW facilitated discussions with structural engineers about reusing existing concrete foundations. Since concrete production is a significant contributor to carbon emissions, repurposing these foundations could yield substantial environmental benefits.

Overcoming challenges in sustainable construction

Despite its promise, integrating salvaged materials into construction projects presents significant challenges. The UK construction industry lacks the infrastructure to fully support material reuse, and careful deconstruction—essential for recovering materials—is both time-consuming and costly. Transporting and storing reclaimed materials adds further complexity.

Timber, in particular, poses unique challenges due to its susceptibility to damage and moisture. Furthermore, the presence of nails and any type of metal parts within reclaimed timber represent a real threat to current reprocessing methods. This particular area requires significantly more research and investment, in order to find suitable solutions that can support the reuse of timber in construction. These practical and logistical issues, combined with budget constraints, often deter clients and contractors from pursuing the reuse of salvaged materials.

A model for sustainable construction in Wales

The Bontnewydd School project is currently undergoing the process of boldly tackling these challenges, aiming to demonstrate the feasibility of sustainable construction practices in Wales. By tackling these challenges, the project aims to set a precedent for future developments, inspiring the Welsh construction sector to embrace circular economy principles and adopt greener practices.

Broader Impact of the Bontnewydd School Project

The project’s benefits will go beyond environmental gains. By showcasing innovative approaches to sustainable construction, Bontnewydd School will serve as a valuable case study for policymakers, architects, and builders. The aim is to showcase that reclaimed materials can effectively reduce waste and embodied carbon, offering a practical and cost-effective path toward sustainability.

The project also fosters community engagement by involving local stakeholders in the design and construction process. This collaborative approach strengthens community ties and builds a sense of ownership. The integration of modern community facilities into the school’s design further amplifies its positive impact, ensuring benefits for the wider community.

A vision for the future

Woodknowledge Wales’ is dedicated to advancing sustainable practices in the built environment. Pushing the boundaries of what is achievable with salvaged materials helps shape a more sustainable construction industry in Wales and beyond.

The lessons learned from the Bontnewydd School project project provide a valuable roadmap for future initiatives. As the construction sector grapples with the challenges of climate change, projects like Bontnewydd School highlight the potential of circular economy principles to reduce waste and prioritise reuse. These efforts are vital steps toward a greener, more sustainable future.

The Bontnewydd School project is more than a building—it’s a symbol of innovation and sustainability. This initiative is proving that salvaged materials can play a central role in modern construction, setting an inspiring example for others and paving the way for a greener future in Wales.

The Secret Campsite honoured for sustainable design excellence at the Scottish Structural Awards

by

Embracing the principles of a circular economy by prioritised material reuse not just at the end of the building’s life but from the very beginning led to a remarkably low-carbon and low-cost building

Congratulations to Toby Maclean and his team at Allt Environmental Structural Engineers, Shaun Ryder of Rural Workshop and Local Works Studio who have been recognised with the “Best Sustainable Design Project” award at the Scottish Structural Awards. This accolade, awarded to The Secret Campsite project on behalf of the Secret Camping Club, celebrates their innovative all-timber approach, including reclaimed materials and timber foundations, in their latest project.

The Scottish Structural Awards, organised by the Institution of Structural Engineers (IStructE), highlight outstanding achievements in structural engineering, with a focus on sustainability and innovation. Allt Environmental’s project stood out for its commitment to environmental responsibility and resource efficiency.

“The highly collaborative approach between builder, engineer and architect led to flexibility with material selection according to local and reclaimed availability and the sketch format used for construction drawinqs enabled a rapid response to changes and build preferences,” explained Toby Maclean, founder of Allt Environmental Structural Engineers and Construction | Independent advisor for Woodknowledge Wales.

The Secret Campsite in East Sussex

The new amenity and facilities building at The Secret Campsite in East Sussex showcases an extraordinary commitment to sustainability and environmental sensitivity. Designed as the ultimate “light-touch” structure, this project minimises its ecological impact from inception to execution.

Accessible and family bathroom

Initially, the client had received planning approval for a standard concrete block amenity building for showers and washing facilities. However, they became dissatisfied with the environmental and aesthetic impact of the proposed design and its cost. Seeking a better solution, they approached the team to create something more aligned with their values and the site’s unique character.

The team collaborated with architects to develop a strategy cantered on using locally available materials, including some sourced directly from the site. By embracing the principles of a circular economy, the project prioritised material reuse not just at the end of the building’s life, as is often the case, but from the very beginning.

A timber frame structure was chosen, supported by reused telegraph pole posts that cantilever from the ground, eliminating the need for carbon-intensive foundations. Locally sourced larch and sweet chestnut were used for the superstructure, ensuring minimal environmental impact and a harmonious fit within the surrounding landscape.

The result is an airy, lightweight building that not only enhances the campsite’s amenities but also aligns with its sustainable ethos. This standout feature elevates the campsite’s appeal while being procured at a lower cost than the original standard design. This project exemplifies innovation, environmental responsibility, and a forward-thinking approach to sustainable construction.

Calculating embodied carbon in this unusual building

While the building is unheated and so avoided the embodied carbon associated with insulation, the approach adopted can still be seen to have led to a remarkably low-carbon and low-cost building with many principles applicable to “more usual” buildings.  The dedication to re-use of materials and use of natural materials is the predominant driver behind this.

“We have undertaken an embodied carbon calculation in accordance with the generally accepted RICS methodology via the IStructE  / Elliott Wood carbon calculator and verified this through in-house tools,” explained Toby. “Note that a nominal carbon intensity figure of 0.1 kg CO2e/kg was used for reclaimed metal roofing and reclaimed timber to cover the recovery and transport emissions.”

The results were calculated for the structural elements only and separately for the whole building (excluding fittings) and they show the building performs exceptionally well achieving an A++ score across the board.

This recognition from the Scottish Structural Awards underscores Allt Environmental’s dedication to advancing sustainable practices in structural engineering.

Cross Laminated Cascades in Cardiff  

by

Social Housing Developers Community of Practice get the chance to visit the Cascade’s seven-storey CLT structure to see how much progress is being made by Linc Cymru

The Cascade’s CLT structure being assembled by Eurban on site in August 2024 
 

There are many social housing projects in Wales that use timber structural frames. More and more new homes are being built from timber frames made in a factory, off-site, and delivered to site for rapid assembly. Until now however, there haven’t been many new homes designed using engineered timber. 

Inspired by a Passivhaus Conference presentation on CLT and Milan’s Bosco Verticale, Linc Cymru (part of the Pobl Group) made the decision to develop a mid-rise block of apartments in Cardiff’s City Road using a form of engineered timber which is a much more familiar construction material in continental Europe. Cross Laminated Timber, or CLT, is a product made from five layers of solid timber glued together, to make a rigid, strong, lightweight and low carbon alternative to concrete and steel.  

The structure for all seven storeys of the new Cascade Tower took shape back in the summer of 2024 where, over the course of a few months, specialist designers, Eurban, erected the individual panels of CLT, which slotted together neatly onsite, within the fine tolerances this engineered material allows. 

The Cascade Tower’s CLT structure provides the inner skin of the building’s external walls, all main internal load bearing and compartment walls, floors, roof deck and roof top terraces. The structure sits on reinforced concrete piled foundations with concrete pile caps and ground beams. The outer leaf of its external walls will be faced in brickwork with coated metal cladding to landings and above roof terraces. Windows will be uPVC. Structural steel is used for large spans and the stair and lift core which will home steel stairs and external landings.  

Designed with biophilic considerations in mind, the building will have plants growing in containers on facade with an irrigation system and a green roof with photovoltaic panels. The internal space and water will be electrically heated, and the building will have a mechanical ventilation and heat recovery (MVHR) system to bring fresh air into the building and capture the heat energy in the stale air as it leaves the building.  

In October, members of our Social Housing Developers Community of Practice got the chance to visit the project, to see how much progress is being made. Linc Cymru’s Richard Hallett and contractor  Langstone Construction’s Scott Eames showed us around and described the challenges of building on such a confined city centre site and the precision of the CLT frame once it had been erected. 

Cardiff Council has supported Linc Cymru throughout the project. Initially this involved grant allocation within the development programme. Linc Cymru  is currently working with the Council on an agreement for the letting and management of the apartments once complete. 

Woodknowledge Wales members with a good head for heights visit the Cascade Tower project in October. 

The Cascade Tower is a £10.9M project, part funded by Welsh Government through the Innovative Housing Programme and Social Housing Grant. It will provide 48 1 bedroom apartments and has been designed by Cardiff practice Powell Dobson Architects and is being built by Langstone Construction Group. It’s due for completion in September 2025. 

In October members of our Social Housing Developers Community of Practice got the chance to visit the project. They were given a tour of the project by Linc Cymru’s Richard Hallett and Langstone’s Scott Eames.

New insights into affordable housing: Woodknowledge Wales members, Jon James Studio Architecture sets the stage with ‘Creating Homes, Not Housing’

In the realm of affordable housing, few voices are as passionate and insightful as Jon James Studio Architecture. Known for their dedication to quality and community-centred design, they’ve recently released a powerful new document, “Creating Homes, Not Housing” that tackles the pressing issues facing affordable housing in the UK.

“As a studio, we wanted to step back from the busy day to day to really understand and analyze the challenges and complexities involved with creating homes that fall under the ‘affordable banner.’”
—Jon James Studio Architecture, in “Creating Homes, Not Housing”

Jon James Studio Architecture’s lead designers have taken a moment to pause, reflect, and evaluate their experiences in designing affordable homes—an opportunity, they say, to step back from the day-to-day grind and dive deeper into the challenges they face. “As a studio, we wanted to step back from the busy day to day to really understand and analyse the challenges and complexities involved with creating homes that fall under the ‘affordable banner’,” they share. “We needed to capture our experience to date around creating the highest quality homes in that context. We intend to continue to review and discuss with others and welcome comments and other experiences from those passionate about how we can together improve the quality of all our homes.”

Their reflections come at a time when public conversations about affordable housing are stirring up significant discourse, especially in light of The Observer’s recent feature, “They look like homes for rich people”: why Britain should look to Europe for its council housing revolution by Rowan Moore, published Sat 9 Nov 2024.

As Jon James Studio Architecture sees it, the future of affordable housing lies in reframing it as “Creating Homes, Not Housing.” By focusing on this mindset, they believe it is possible to establish homes that are not only high quality but also resonate deeply with the needs and spirit of the communities they serve.

“The document highlights how critical interdisciplinary collaboration is to the success of building quality homes and places.”
—Jon James Studio Architecture, in “Creating Homes, Not Housing”

5 Principles of Good Design in Affordable Housing

    The guide encapsulates five principles of good design, emphasising that context should serve as the “golden thread” uniting every aspect of the design process.

    1. Contextual Sensitivity – Design should align with the character, history, and needs of the local area.
    2. Quality of Space – Both interior and exterior spaces should enhance residents’ daily experiences.
    3. Sustainability – Environmental considerations should be integral to design, from materials to energy use.
    4. Inclusivity – Spaces must be accessible, welcoming, and adaptable to different lifestyles.
    5. Longevity – Homes should be built to last, providing durability and ease of maintenance over time.

    At a time when the housing crisis is intensifying, their work showcases the benefits of an interdisciplinary approach, bringing together architects, urban planners, clients, and consultants to craft homes that stand as examples of thoughtful design and community well-being. “We have been fortunate to work with some inspirational clients and consultants,” they say. “This has given us the opportunity to see, and learn, how this can be achieved through collaboration. The document highlights how critical interdisciplinary collaboration is to the success of building quality homes and places.”

    Key Concept: The Golden Thread of Context

    In affordable housing, context is more than just a design element—it’s the “golden thread” that weaves together the architecture and community needs. By prioritizing the local context, architects can create spaces that feel integrated and meaningful to residents. As Jon James Studio Architecture emphasises, “understanding and respecting the environment around a home ensures it becomes a genuine part of the community, enhancing both social and environmental well-being.”

    Feedback invited

    This new publication, available here on Issuu, is designed to be accessible and actionable, providing valuable insights and resources to anyone involved in residential development. Whether you’re an architect, designer, planner, or simply someone invested in the future of affordable housing, Creating Homes, Not Housing is a valuable resource. Jon James Studio Architecture invites feedback and insights from others in the field to continue pushing the boundaries of what affordable housing can be.

    For more information or to connect directly with Jon James Studio Architecture, visit their website or reach out to them directly. They welcome all dialogue that seeks to elevate the quality and integrity of affordable housing in the UK and beyond.

    Housing’s better future

    Social Housing Developers Community of Practice members enjoy a hosted tour to include both off-site creation of timber frame panels and on-site progress at the Gwynfaen Project

    Members of Woodknowledge Wales, colleagues from Welsh Government and Hale Group at the end of the Gwynfaen tour

    On 21 October 2024, members of Woodknowledge Wales’ Social Housing Developers Communities of Practice (CoP) made two linked site visits to see how timber is being used to make new homes t near Swansea. This event enabled CoP members to see both the off-site creation of timber frame panels at the SO Modular factory in Neath, and the on-site progress at Pobl Group‘s Gwynfaen Project (Penyrheol, Swansea) which has been referenced in many discussions over the last few years.

    The visit proved to be an opportunity to watch the process of transforming lengths of home-grown timber into the panels that, once taken to site and assembled, make up the shell of new energy efficient homes. On a site overlooking the Loughor Estuary and with a view of the Gower peninsular work is underway on the third phase of the project which will create 144 new high performance homes.

    Sevenoaks (SO) Modular factory in Neath

    The day began at Sevenoaks (SO) Modular’s factory in Neath. We started with a presentation by Head of Production and Technical Efficiency Warren Rowlands – someone well respected by his peers for his knowledge and his willingness to share it, in what is a very competitive, commercial environment. Warren explained the approach to timber frame construction and some of the challenges in off-site manufacturing. 

    Panels being framed at a workstation 

    The tour of the factory walked everyone through the stages of creating the key components of the timber frame homes, including the optimised cutting of the timber, the nailing of the frames, automated insulation with wood fibre and the installation of doors and windows. 

    Windows and doors are installed in the timber frame panels.

    Wood fibre insulation fills each panel before it’s closed up.

    Pobl Group’s Gwynfaen site in Penyrheol, Swansea

    Hale’s Tom Bevan talks about the specification and achieving airtightness targets.

    From the factory we headed from Neath to Gwynfaen site in Penyrheol, Swansea. From the site office, Hale Group’s Construction Director Tom Bevan and Pobl Group’s Project Manager, Peter Remedios, took everyone around the third phase of the project. Our hosts pointed out the progression of new homes from initial site delivery and assembly, through the stages of completion, highlighting some of the key features of the individual homes and the site. 

    Phase 3 homes under construction. External finishes include render and timber cladding.

    The homes are weather-tight within a week of the panels arriving on site and the completed homes are finished in around six months.  

    The Gwynfaen Project has been designed as a high-quality, cohesive and sustainable community using rural planning principles and being led by a strong green infrastructure and placemaking approach. The notion of ‘combustion free living’ has challenged some of the more conservative and traditional ‘gatekeepers’ but as with all developments, compromises have been struck in order to make progress. 

    Pobl Group’s Elfed Roberts outlines the approach to placemaking at Gwynfaen 

    The site tour finished with a look into some of the culs-de-sac of completed timber clad homes and a visit to the Sales & Marketing Suite. Here we were able to see the completed layout of rooms and how the fabric of the new homes has accommodated the technology to reduce the energy needs of the occupiers. Built in technology includes air source heat pumps, solar photovoltaics, batteries and mechanical ventilation and heat recovery systems. Requirements for the project also include the use of Welsh sourced timber for the superstructure (panels) along with wood fibre for the insulation, Welsh Larch cladding and timber triple glazed windows and doors.

    Appreciating the completed homes and spaces 

    The Gwynfaen Project has further phases ahead and it’s likely that the precise design and manufacture of the homes will continue to be refined as a result of the off- and on-site experience of the client and contractor. We look forward to a return visit at some point. 

    For Woodknowledge Wales, site visits like these provide important opportunities for members to see how the ideas and concepts discussed at CoP meetings are becoming a reality. They are important networking opportunities, a chance to be inspired, introduced to fresh thinking and where solutions to common problems can be shared.

    We wish to thank both So Modular and Pobl Group for making this visit possible.

    For further information about future site visits, please contact David Hedges.

    Bio Materials in Retrofit: An Industry Perspective at AECB Annual Conference

    by

    Applying best practice to create sustainable timber solutions for homes across Wales

    On Friday 27th September 2024 at 2pm during the AECB annual conference in The National Self Build & Renovation Centre in Swindon, audiences enjoyed a joint presentation from Dr Diana Waldron, Head of Built Environment for Woodknowledge Wales, and Richard Hawking, Technical Innovations Manager from SO Modular.

    Diana’s contribution included a short ‘show and tell’ session demonstrating the use of Building Performance Evaluation (BPE) equipment and promoting BPE in Retrofit.

    “The conference was a great success with over 150 delegates this year, and we have already started to receive plenty of positive feedback. Your [Woodknowledge Wales’] contribution played a significant role in the success of the event and it was a privilege to have you involved. Your breakout session went down really well – it has featured heavily in our feedback,” wrote Michelle Youngs, Events, Communications & Marketing, AECB

    About the Home-Grown Homes for Retrofit Optimised Retrofit Program (ORP3)

    Working in collaboration with industry, community groups and Local Authorities, Woodknowledge Wales (WKW) works to assist the construction industry in it’s approach to retrofit by advocating for sustainable practices and the use of natural materials. The aim is to transform existing housing into ‘Beyond Net Zero’ liveable homes, as part of UK Research and Innovation’s (UKRI) Green Transition Ecosystem awards.

    Current retrofitting methods heavily depend on synthetic materials like plastics and foam insulation, which can result in high embodied carbon emissions that overshadow the carbon savings from energy reductions. WKW addresses this by working with partners like SO Modular to bring innovative timber-based solutions into the retrofit sector, significantly reducing carbon footprints.

    Through its collaboration with the GW4 Climate Alliance, WKW is involved in developing an Optimised Retrofit Program (ORP3) with Welsh housing associations. Part of the wider Home-Grown Homes project, this program integrates sustainable approaches into retrofitting existing homes, with a key emphasis on natural, renewable materials like wood and wood-fibre insulation, which can provide both environmental and health benefits. SO Modular, a company specialising in timber frame construction, aligns with these values, offering sustainable timber solutions that prioritise speed, eco-friendliness, and reduced embodied carbon in retrofitting and new builds alike​.

    Woodknowledge Wales emphasises community engagement in the retrofit process. By involving occupants early on, the project fosters positive responses to retrofit initiatives, ensuring that changes made are beneficial and well-received. This staged approach includes evaluating opportunities to use natural materials based on performance results, further enhancing the sustainability of retrofit efforts.

For housing directors, these insights highlight the importance of balancing cost, carbon emissions, and operational efficiency, while adapting to climate challenges through resilient and sustainable practices.

    Circular Economy and Low Carbon Development

    Workshops on the circular economy and low carbon development provided practical examples and case studies, such as the Gwynfaen project’s use of timber to reduce whole-life carbon. These sessions revealed the need for better standards, networks, and policies. Directors should consider these examples to enhance their sustainability strategies, focusing on circular economy principles and low carbon solutions to meet regulatory requirements and achieve project goals.

    Building Performance Evaluation

    Building Performance Evaluation (BPE) was highlighted at WoodBUILD 2024 as a crucial element for enhancing the effectiveness of sustainable design and construction. This process involves assessing building systems and operational performance to ensure they meet intended sustainability and energy efficiency goals. For directors, incorporating BPE into project management helps identify areas for improvement, optimise resource use, and achieve long-term performance targets.

    Advancing Carbon Assessment Tools

    Finally, the session on embodied carbon and footprint assessment tools highlighted the importance of integrating these tools into early project planning. As regulations evolve, continued refinement and collaboration are essential. For senior management, leveraging these tools can aid in precise carbon accounting and support efforts to mitigate climate impacts effectively.

    Conclusion: Driving Industry Transformation

    WoodBUILD 2024 has demonstrated that the path to a sustainable built environment involves collaboration, innovation, and a commitment to continuous improvement. For B2B leaders in social housing and the built environment, the conference’s insights and actionable strategies offer a roadmap for integrating sustainability into every aspect of their operations. By embracing these recommendations, investing in workforce development, and leveraging advanced materials and technologies, industry leaders can drive significant progress towards a more sustainable and resilient built environment.

    As we move forward, it is crucial for senior management and directors to stay engaged with industry developments, foster partnerships, and lead by example. The future of the built environment depends on our collective efforts to innovate, adapt, and commit to sustainable practices.

    Duncan Baker Brown, founder of BakerBrown Studio, a practice focussing on architecture and the circular economy, is a leading voice in sustainable architecture. He has spent over 25 years pushing the boundaries of sustainable development and circular design. His journey from a passionate environmental activist to an influential architect and academic has been driven by a commitment to addressing the climate and ecological emergencies through innovative design practices.

    Duncan will be part of an enticing panel of speakers, including Katherine Adams from Reusefully, Richard Farmer and Sioned Hughes from Gwynedd Council. This session will be hosted by Dr Diana Waldron, Head of Built Environment, Woodknowledge Wales and chaired by Seb Laan-Lomas, Associate and Passivhaus Designer, Architype. This will be one of the parallel sessions taking place on the second day of WoodBUILD 2024 in Swansea, at 11:30 on Wednesday 3 July.

    “We are really excited to offer this opportunity for our conference delegates to engage with this amazing panel of speakers. We will be discussing important issues around circular economy, with a particular focus on what can we do to encourage and implement the reuse of materials in construction. This is still quite a niche area in the UK, a situation that is unacceptable in a country that has already declared a Climate Emergency. Why are we still struggling to assist our construction industry in their efforts to reuse perfectly good quality building materials? The fact is that we are still sending large quantities of construction waste to landfill unnecessarily, just because that’s the way the system works here in the UK. We need to join forces to change this and find suitable solutions. We hope this session will bring us a step closer to nudge our industry in the right direction.” Dr Diana Waldron, Head of Built Environment, Woodknowledge Wales.

    Duncan recently announced his candidacy for RIBA President, aiming to bring circular economy principles to the forefront of the architectural industry. His practice, BakerBrown, focuses on research-led architectural and consultancy services designed to meet the challenges of a post-COVID world while addressing climate demands.

    Circular Economy in Practice

    Duncan’s work, both in practice and academia, has garnered numerous accolades, including RIBA National Awards and the Stephen Lawrence Prize for the Brighton Waste House. The prize money from the latter has funded a student prize for circular design at the University of Brighton, where Duncan teaches.

    The Brighton Waste House, a project made from waste materials, has evolved from a pedagogic tool to a serious research project. “We’ve installed old duvets as insulation and tiles made from discarded oyster shells,” Duncan explains. “Monitoring their performance has been insightful. The house has gained attention from media and has become a platform for funded research projects.”

    Driving Change in the Industry

    Duncan believes collaboration is key to integrating circular thinking in architecture. “It’s important to bring together financial modellers, urban miners, architects, and academics,” he says. “The people on the ground are really making a difference.”

    His approach is not just theoretical. BakerBrown has been at the forefront of sustainable design since winning the RIBA ‘House of the Future’ competition. Their notable projects include the circular economy-influenced Greenwich Millennium Village and The House That Kevin Built, the UK’s first A* Energy Rated Building.

    Innovative Materials and Techniques

    One of the innovative techniques Duncan’s practice employs is harvest mapping. “We take a 5-10km radius around the site to find materials to use,” he explains. This method reduces the carbon footprint associated with transporting materials and supports local economies.

    BakerBrown is also involved in an EU-funded research project aimed at finding alternatives to cement, one of the most carbon-intensive materials in construction. “We’ve created beautiful tiles from oyster shells,” Duncan says. “They’re made from 90% calcium carbonate, the same as limestone.”

    Future Projects and Visions

    Looking ahead, Duncan is excited about a new project inspired by the Brighton Waste House. “The next project is a deconstruct/reconstruct initiative. We’ll dismantle a building slated for demolition and use its materials to construct a new building. It’s about showing that there’s no such thing as waste.”

    This vision extends to advocating for reconfiguring existing buildings rather than demolishing them. “In London, buildings are constantly going up and down. We can present alternatives that don’t involve starting from scratch.”

    Building a Sustainable Future

    At BakerBrown, there’s a strong belief that good design and sustainability go hand in hand. “Our buildings are about material, light, and time,” Duncan says. “They function beautifully, age well, and work with the planet, not against it.”

    By partnering with private clients, developers, and local authorities, BakerBrown has demonstrated that it’s possible to build sustainably without compromising on aesthetics. Their work champions the circular economy, using local materials and resources, and focusing on retrofitting and adapting rather than demolishing.

    Communication and Education

    Duncan is also a passionate communicator. From international symposiums to TEDx talks, Duncan’s influence extends across the globe, inspiring a new generation of architects to embrace circular economy principles. His mission is to spread the message that the built environment can play a crucial role in addressing the climate crisis. “If the built environment is responsible for nearly half the world’s carbon emissions, then it also holds the key to creating a better future,” he asserts.

    By championing the circular economy, Duncan is paving the way for a more sustainable future in the construction industry. His journey, marked by groundbreaking projects and a commitment to education and collaboration, serves as an inspiration for architects and builders everywhere to rethink their approach and embrace sustainable design.

    For those in the timber industry and beyond, Duncan’s message is clear: sustainable design is not just possible; it’s essential for our future.

    Don’t miss the opportunity to hear Duncan speak and collaborate with him, Katherine Adams from Reusefully and ASBP, Richard Farmer and Sionned Hughes from Gwynedd Council, and both Dr Diana Waldron from Woodknowledge Wales and Seb Laan-Lomas from Architype.
