In the context of the climate crisis it is necessary to find radical new solutions to dense housing typologies which address embodied carbon as well as in-use energy. This proposal explores the use of mass timber frame structures in high rise residential towers and the potential role of the column in this system as both a structural and spatial device. The design uses a simple column grid to provide open plan, flexible living spaces for the inhabitants of the building. The mass timber structural columns free up the internal walls to vary from storey to storey, forming a series of dynamic private and public spaces. The columns themselves carry both loads and services, forming seats, storage and staircases. The plan leaves room for potential change and unprogrammed activities to take place, anticipating but not prescribing its future uses.
