The building ## The Office Agents Society named Axtell House Best Delivered Scheme West End in 2022. Axtell House is a locally valued building in the Soho Conservation Area. Westminster's planning committee backed its redevelopment in December 2016: floors four to six rebuilt, the core moved and a roof garden added. To keep loads off the retained structure, the new floors were built as a steel frame with cross-laminated timber floors. RED Construction kept the ground-floor restaurant trading through demolition, piling and rebuilding. The structure topped out in March 2018 and the building was complete in spring 2019. ## Design, construction and the finished interior The design model, the rebuild under way and the finished interiors, shown for context: RED Construction's and other teams' work. ![3D external model of Axtell House from above, showing stepped stone bays, a bronze-finned top floor and a planted roof garden](https://dmitrodevelopment.co.uk/assets/projects/axtell-house-soho/axtell-house-soho-3d-external-model-stepped-stone-bays-fallback.jpg) 16 · 3D model of the design: stone bays, finned top floor and roof garden.
