Seb joined Architype in 2021 and is an expert in sustainable design and policy, contributing to industry initiatives to decarbonise construction.

Seb is involved in various practice research initiatives on post occupancy evaluation, embodied carbon, policy and structural timber, and is a member of Architype’s climate action team. He has also worked with the City of Edinburgh Council on their EnerPHit-informed retrofit plan to decarbonize their portfolio of existing buildings.
