Episode 46. AJ Climate Champions with Hattie Hartman and George Morgan. Andrew Waugh explains how building with timber can address industry transformation at scale. ‘I want to transform the whole industry,’ says Waugh, founding director of Waugh Thistleton which was recently named Practice of the Year at the AJ Architecture Awards.

In this episode Waugh explains why tall buildings have no place in sustainable cities of the future; how building housing with timber can reduce its carbon burden by as much as 75%; and why we should stop building basements (they are up to five times as carbon intensive as upper floors).

Waugh advocates building with timber primarily as a low-carbon alternative to concrete and steel, rather than for aesthetic reasons. He shares recent research that clarifies end-of-life alternatives for timber that are not incineration or landfill. He makes it clear that current subsidies that encourage burning of timber for biomass must be revamped to support use of UK-grown timber for construction.

This episode was recorded the day after Waugh toured co-hosts Hattie and George through Waugh Thistleton’s recently completed Black & White Building in Shoreditch. The building is nearly all timber: structure, core, floors, cladding and brise-soleils. Waugh describes where the timber was sourced and that the transport footprint of timber is a relatively minor consideration.

Finally, Waugh explains why he recently withdrew from the Architects Declare steering group.

A previous version of this podcast mistakenly suggested that Waugh Thistleton had withdrawn from Architects Declare. In fact, Andrew Waugh withdrew from the Architects Declare steering group in May on an individual basis and Waugh Thistleton remains a member of Architects Declare. We apologise for any confusion.
