TABBERNER COOK HOUSE

PLANNING PERMISSION SECURED 
CURRENTLY ON SITE

Tabberner Cook House is a proposal for a very large, split-level ground floor extension to a home in Crystal Palace, London. Planning Permission for the scheme was granted in late summer 2022, and the project began construction on site in the summer of 2023.

An engineered, exposed structural timber frame sits atop a white brickwork and concrete plinth, clad at higher levels externally in a plain anodised aluminium. Internal planters, an internal greenhouse, and a large set of split-level living spaces, extend outward and downward to the terraced garden beyond. The exposed corner site slopes heavily across its length, allowing for multiple stepped levels both inside and out.
