Loadbearing Stone Redefining Low-Carbon Construction

Finchley Road is a mixed-use development in north London designed by Groupwork with structural and building services engineering by Webb Yates Engineers. The project comprises three buildings, including a ten-storey structure, and explores the use of natural stone as a primary load-bearing structural system rather than a conventional façade finish. Approximately 725 tonnes of Larvikite from Lundhs in Norway, chosen for its exceptional compressive strength, form the building’s external stone exoskeleton, carrying both vertical and lateral loads while eliminating the need for a secondary structural frame.

The structural system consists of precision-engineered stone beams and columns assembled as a post-and-lintel frame. The stone elements were fabricated off site to tight tolerances before being delivered through a coordinated logistics strategy suited to a constrained urban site. By combining structural performance, façade function and material expression within a single system, Finchley Road challenges the separation between structure and envelope common in contemporary construction. The project demonstrates how natural stone can be used as the primary structure without the need for stainless-steel reinforcing bars or secondary structure in modern low-carbon construction
