What the Client Needed
A family of five in a 1960s Dulwich detached needed two additional bedrooms and a larger kitchen but had already used their garden space for a single-storey utility room. Full planning permission was required for a two-storey rear extension that would match the existing roofline and brick bond. Southwark Council's design officer required material samples and a 3D model before approval.
Before & After
Key Architectural Features
- Reclaimed London stock brickwork
- Internal courtyard light well
- 35 m² kitchen-family room
- Seamless roofline matching
What We Delivered
The two-storey extension added a 35 m² kitchen-family room on the ground floor and two bedrooms with a shared bathroom above. We sourced reclaimed London stock brick to ensure a seamless match with the 1960s originals — the join is virtually invisible. An internal courtyard light well between the old and new structures floods the central hallway with daylight, solving the 'dark corridor' problem that plagues most double-storey extensions.
“The light well was a stroke of genius. Every builder we spoke to wanted to just bolt on a box — APEX actually designed something that improved the whole house, not just the new part.”
