Set on a quiet, tree-lined avenue in Chelsea, this extraordinary 12-bedroom house unfolds across five expansive storeys and is the amalgamation of two houses combined into one, measuring over 9,128 sq ft of lateral living space. Formed from the careful unification of a single house and five apartments, the building was entirely rebuilt in 1999 and has remained under the same family’s ownership ever since. The result is a rare and remarkably lateral freehold private home, independent in orientation and monumental in scale, designed by an Italian architect and finished with decorative flourishes from Paris.

The house is defined by a sense of grandeur, openness, and light. Nowhere is this more evident than on the second floor, which is entirely dedicated to a vast reception room, offering a dramatic sense of volume and clarity. A second, more intimate reception room sits on the raised ground floor, with tall sash windows that open directly onto the garden. Throughout, a calm palette and elegant proportions speak to a timeless sensibility, with each space carefully considered for both formal entertaining and everyday life.

The principal suite occupies much of the first floor and is conceived on a truly impressive scale. A generous bedroom flows into an enormous walk-through dressing room and onward to an en suite bathroom. Additional bedrooms, eleven in total, are arranged across the upper and lower floors, allowing for a fluid division between family life, guests, and staff. Two offices, both on the upper ground floor, dressing areas and utility spaces have been integrated seamlessly throughout the home.

At garden level, the kitchen sits at the heart of the lower ground floor. Bright and generous, it opens directly onto the expansive private garden, which itself is the result of joining two original plots. Behind, a closed garage is discreetly positioned for added privacy, while a gated driveway at the front provides further off-street parking.

While the house is laid out across five storeys and does not include a lift, its internal flow is logical and gracious, with a wide central staircase connecting each floor.

Tregunter Road is one of Chelsea’s most architecturally distinguished addresses, lined with grand villas and enveloped in greenery. The house is quietly positioned yet moments from the Fulham Road and King’s Road, close to independent restaurants, cafés and galleries. There are also excellent schools in the vicinity. Central London is quickly accessed by Gloucester Road and South Kensington Underground stations, both within walking distance.
