Webb describes what it will take to transform an industry fixated on concrete and steel, and outlines simple steps to decarbonise Victorian house extensions, while Meynell explains the budget challenges of low-carbon retrofit and why architecture is essentially political.

About Steve Webb
Webb Yates co-founder Steve Webb has pioneered the use of structural stone as an abundant low-carbon alternative to concrete. Last year he collaborated with Amin Taha of Groupwork on the New Stone Age exhibition at London’s Building Centre.
Unafraid to challenge clients to consider building with timber, Webb has successfully increased the use of timber on recent projects such as the Hoover Building and York House.

York House (2019) by dMFK Architects
At York House, Webb Yates was instrumental in persuading the client to extend the 1980s building near King’s Cross to the front with a CLT structure behind a self-supporting perforated brick screen. Two new floors on top of the existing building also have a CLT structure.
Hoover Building (2018) by Interrobang/Webb Yates Engineers
In the conversion of the Hoover Building to residential use, Webb Yates proposed the replacement of steel partitions between units with gang-nail trusses, resulting in significant cost and carbon savings.
