A grand double fronted townhouse in the heart of the Mayfair Village, Balfour House is arguably the best house in Mayfair. With beautiful proportioned accommodation, triple aspect windows to the south, east and west, a lift to every floor and large roof terrace, the house retains the feel of a comfortable family home whilst being totally unique.

This exceptional townhouse, arguably the finest in Mayfair, occupies a prime position within the prestigious Mayfair Village, and offers beautifully-proportioned living spaces that retain the warmth and charm of a true family home.

Having undergone an extensive redevelopment, the property features four formal reception rooms – a sitting room, dining room, drawing room, and study– spread across the ground and first floors. The dining room has French doors that open onto a private garden, while the top floor is a spacious 200-square-foot open-plan family room. On the upper floors, all accessible by a generous lift, the principal bedroom located on the second floor, is a luxurious private suite complete with a dressing room, and beautifully designed his and hers octagonal bathrooms. The third and fourth floors each house two bedroom suites, all with dual aspects, a feature shared by all the principal rooms in the house. The kitchen, situated below the ground-floor dining room, includes a rear staircase that leads to a servery kitchen next to the dining room.

The rest of the lower ground floor is dedicated to a self-contained staff flat, with one bedroom and bathroom, sitting room, a utility room, and additional storage space.

The best part of the house is saved to last with a 525 sq ft roof terrace with a 360º view of the London skyline. Nestled in a tranquil and highly sought-after enclave, equidistant from Hyde Park and Grosvenor Square, the residence is just 100 yards from the serene gardens of Mount Street and the hustle and bustle of Harrys bar and George Club
