This 7-bed property in London (SW13) is asking just 0.38× the local £/sqft, listed at £9,995,000. 7-bedroom property — well above the typical sale in London.

Located on the exclusive Barnes Village side of Castelnau — a name with historic ties to Castelnau-le-Lez in southern France — this remarkable home combines privacy, scale and timeless architectural elegance. Dating back to the late 17th century with connections to the Boileau family, the property enjoys a rich local heritage while offering contemporary luxury on an impressive scale. Set behind secure electronic gates, the house is approached via a sweeping driveway with ample parking. The grand entrance hall sets the tone for the interior — light-filled, spacious and finished to exacting standards throughout. Reception Floor The main level offers a wealth of versatile reception spaces including a formal bay-fronted double drawing room with intricate ceiling plasterwork and feature fireplace, a formal dining room, cloakroom, and a charming snug. A conservatory and an expansive open-plan family room with striking glass flooring (offering a unique view into the pool below) open directly onto the terrace and garden, creating a seamless connection to the outdoors. Lower Ground Leisure Floor A true highlight of the home is the exceptional leisure suite. This level comprises a private cinema, games room, bespoke wine cellar, and an indoor swimming pool with a dedicated gym area, sauna, steam room, and adjacent sitting area. A separate cloakroom and shower room serve this floor. Bedrooms and Bathrooms The first and second floors host six well-appointed bedrooms. The principal suite is a sanctuary of its own, complete with dressing room, luxurious bathroom, separate cloakroom, conservatory, and private roof terrace with panoramic views over the Wetlands. Also on the first floor are two further double bedrooms, each with en suite bathrooms. The second floor offers three additional bedrooms and three bathrooms, ideal for family and guests alike. Grounds and Views The beautifully landscaped rear garden backs directly onto the London Wetlands, providing breathtaking natural views and regular visits from grazing sheep and Highland cattle — a unique rural ambience within the capital. Location This exceptional home is located in one of Barnes’ most prestigious addresses, moments from the River Thames and within easy reach of Central London and Heathrow via the A4/M4. Barnes and Barnes Bridge stations offer convenient Southern Region rail connections, while Hammersmith’s four Underground lines are also nearby. Barnes itself is renowned for its village charm, independent cafés, restaurants, pond and open green spaces, along with the Wetlands Nature Reserve. Outstanding schools nearby include St Paul’s, The Harrodian, The Swedish School, Ibstock Place, Colet Court, St Osmund’s, Lowther and Barnes Primary. Sporting and recreational facilities are abundant, with The Roehampton Club, the LTA National Centre, Riverside Health Club, and Barn Elms all within easy reach. For those who enjoy the outdoors, Richmond Park and Kew Gardens are just a short drive away. Viewings strictly by appointment.
