Slab Design Union were commissioned to extend and refurbish an existing terraced property in Birmingham that had been extensively modified over the years and was in need of a strategic rethink to accommodate the needs of a young family. The existing site is deceptively tight with a number of constraints to navigate, including ad-hoc boundary conditions and adjacency issues commonly associated with terraced properties. The project comprises the demolition of an existing single storey extension and the construction of a new single storey extension in its place, along with the conversion of the existing kitchen into an ensuite bedroom with a new bay window. The design concept for the new extension is a simple volume linked to the existing property across a single level. A central circulation spine divides the kitchen and living spaces into two distinct spaces with improved access to the private garden. The new extension is finished in a simple and restrained materials palette of London stock brick with black framed doors and glazing, black sills, soffits and copings, and a light precast concrete plinth and steps that connect the extension to the garden.
