Unprecedented price volatility of timber is constraining the development of the timber frame manufacturing sector. This threatens the delivery of Welsh Government’s affordable housing, MMC and zero carbon strategies. The purpose of this paper is to highlight issues of concern and offer first ideas to develop potential solutions.
What is the zero carbon timber housing solution for Wales?
This document proposes a range of timber build solutions. Results are based on the analysis of an appropriate and future proofed definition for ‘zero carbon’, followed by design and calculation to develop an understanding of the quantifiable factors of embodied and operational carbon. Using a fabric first approach, an examination of existing and alternative timber construction methods, materials and systems offers a range of developed timber solutions that are capable of meeting the target fabric specification. These include information on whole carbon emission and offsetting calculations for a range of key typologies demonstrating the routes to Zero.
The detailed report presents findings from the Home-Grown Homes Project including actions for further detailed design, training and skills, technical development and testing, design and modelling tools. These may be relevant for designers, manufacturers, specifiers and clients.
Making the right decisions for the benefit of a building’s long term performance and user experience can be compromised by cost, lack of experience, and poor understanding of timber frame construction.
This guide aims to highlight some of the key points to consider along the pathway of designing, constructing and maintaining timber frame housing.
These points have been compiled reflecting on experience gained by delivering BMTRADA’s frameCHECK on-site quality consultancy service.
By helping the reader understand more about the consequences of some of the decisions to be made during construction.
This report has been compiled as part of the Home-Grown Homes Project, which looked into the way that timber is specified and used in construction, with its focus being on manufacturing. The aim of this document is to help all those involved with timber frame construction to deliver better performing and longer lasting homes.
Explore information on construction, innovative products, use of home-grown timber and Welsh manufacturing, carbon impact and building performance in innovative timber housing projects across Wales.
This map showcases the exemplar timber housing projects Woodknowledge Wales has worked on in some way over the past few years. The Exemplar Housing Project layer contains basic project information. The Whole Life Carbon layer contains data on the carbon impact of those projects for which we have undertaken analyses. The Building Performance layer contains projects where we have undertaken some experimentation into different building performance methods. The Forest Nation Attribute layer attempts to capture the timber story such as the use of innovative products, the use of home-grown timber and the use of Welsh manufacturing.
This map represents our progress to date. We will continue to record the progress of our timber development agenda as well as the progress of Welsh housing in meeting the challenge of Net Zero whole Life carbon over the coming years.

This research was undertaken by Woodknowledge Wales to identify the range of timber construction systems or techniques that are available for use in Wales and to identify the extent to which Welsh-grown softwoods could be utilised in their production.
The projects showcased here represent a snap-shot of what’s happening throughout the whole of the UK, but with an emphasis on projects in Wales – from housing to retail, simple homes and social housing to high end self-build, as well as offices and schools.
FC Scotland have released a new publication by Ivor Davies, Sustainable Construction Timber – Sourcing and Specifying Local Timber. This is an invaluable new tool that will help clients understand how to procure homegrown timber.
This report focuses more particularly on timberdowelled Brettstapel panel manufacture where ‘super’ dry hardwood dowels are used to fix parallel softwood lamellae together.
