The redevelopment of the existing building transformed the Which? HQ to meet the needs of a modern business and charity. Additional NIA has been added by removing sections of the 1980’s concrete core and extending the floor plate with a new core along the western elevation. The transformation is completed by the introduction of a new façade comprised of transparent and translucent glazing panels.
Key Project Features
- An additional floor added with outdoor terrace and feature lead roof designed to minimise the impact on local historic views

- Reception upgraded with high quality materials and finishes to create a smart and contemporary workplace, whilst remaining sympathetic to the nature of the Listed Building
