Sumner Place, London, SW7

A unique opportunity to acquire two houses within a stone's throw of each other. Ideal for a multi-generational family, or for a family who also require further space for staff or security,

8 Sumner Place is a beautifully refurbished town house that was the subject of a 'back to brickwork' restoration by award winning architect Seth Stein, to include the rebuilding of the previous unsightly rear extension. This modern masterpiece is built over two storeys and is accessed from the raised ground and lower ground floor of the original house with a small garden of birch trees in the middle. Connected by a sculptural rear staircase that resembles a sea shell that is both tactile and beautiful, this modern space has a fantastic feeling of scale and light and is cleverly juxtaposed against the original house.

The remainder of the house is beautifully original, but beneath the traditional detail lies state of the art technology and functionality.

The kitchen dining room, living room and the principle suite have a generous full floor each allowing light at different times of the day. Original details like cornices and the working shutters on the full height doors to the balcony have been restored. No radiators can be seen, just a perfectly warmed wide timber plank floor that is perfectly level without a creak. Artwork is lit by gallery lighting.

From the modern features like the rear staircase to the book matched stone and the bathtub carved out of a single block, everything is carefully sculpted and crafted as in times gone by. Luxury has been beautifully and simply crafted by artisans of a modern age but paying respect to the grand designs of the original architect.

Sumner Place Mews is a cobbled cul de sac off Sumner Place. Originally the stable/coach house accommodation for the main houses on Onslow Square, it now serves 8 Sumner Place as a guest house. One of only four houses, it's at the end of the mews, feeling very secluded.

Unusually for a mews house, it has direct access to communal gardens behind. On the outside, the house has all the original charm, but step inside and it has been optimised to make the best use of light and circulation. Like the main house, the heated polished concrete floors reflect light coming in from windows all around. The beautifully designed modern timber staircase is open and forms the core of the house, leading upstairs to two bedrooms. Downstairs, there's a state of the art cinema room and another bedroom. It's perfect as a work from home space, gym, guest house, or separate entertaining space.
