Toby is a structural engineer with a diverse career engineering everything from oil platforms and concert halls to handbags.  He established the successful TALL Engineers in 2005 that went on to build a reputation for providing practical yet technically sophisticated and holistic solutions to diverse projects in the built environment and concentrating on design from first principles, with the firm increasingly concentrating on timber as a structural material.  Having sold this firm, in 2020 Toby established Allt Environmental to atone for past carbon sins and to address the urgent need to decarbonise the built environment especially in relation to embodied carbon. 

Since Allt was established Toby has mixed project work, research and consultancy, with a focus in understanding the environmental impacts of timber in construction.
