Richardson House is an complex internal renovation and a single storey rear extension, to a mid-terrace, three storey townhouse in SW London. The project extensively reworks the interior of the existing house, and updates much of the pre-existing fabric. The extension greatly enlarges the available living spaces, and opens up the ground floor to both the front and to the rear of the existing property.

White brick and concrete lintels create a strong material aesthetic to the proposal, and link into the language of the mid-century tectonics of the existing townhouse. Proportional cues for the interventions are driven by those employed in the ordered construction of these row houses.
