Challenge

Our clients aimed to fill in the "missing" half of a large house that resembled semi-detached homes, turning one home into two without overcrowding the street. The existing house had one full-sized bedroom and two undersized rooms, complicating the task.

Approach

We mirrored the main part of the house at the front while adding a two-storey outrigger and a single-storey extension at the back. This design provided sufficient space for two two-bedroom homes and incorporated air-source heat pumps and a green roof to meet sustainability goals. Given the proximity to local amenities and Thameslink, the development was car-free.

Solution

The project transformed an undersized home into two sustainable two-bedroom houses, enhancing the streetscape without crowding it. This innovative approach maximised the potential of the site, while adding valuable housing to the area.

Before & After

RIBA Registered Architect's layout drawings of the existing ground floor which consitituted of a unfriendly layout with a large living room space but very small kitchen area.
