Located on the border of Hampstead Heath in Camden, the brief for the extension of this single-story garden flat required three bedrooms and an improved relationship with the garden.

Bordered by the Overground railway line and adjacent dwellings, the site boundary was enhanced, providing a private enclosure within which interior and landscaping are carefully orchestrated to soften the relationship between inside and outside. Two extension blocks are the key architectural elements, divided by a full-height entrance door which marks the threshold between the bedrooms and utility spaces arranged to the front of the property, and the living area opening to the garden.

The floor levels of the extension were lowered to improve ceiling heights, and in turn, define a large exterior patio. Openings were carefully positioned to provide good natural daylighting. A palette of grey render, white marble & Oak flooring was used, which contrasts the existing stock brick, and contributes to the tranquillity of the space.
