In the heart of Knightsbridge, Fonteyn House is a rare London home that blends remarkable history with contemporary design. Built in 1928 and once known as Amberwood House, it was home to Dame Margot Fonteyn during her years as prima ballerina of The Royal Ballet, when its rooms hosted Princess Margaret, Yves Saint Laurent, Peter Sellers and Rudolf Nureyev.

 

Behind its retained façade of French windows, ornamental balconies and Portland stone, the house now spans over 15,000 sq ft of newly reimagined space across six floors. The entrance opens onto a mirrored foyer and a gallery of windows overlooking the walled garden. A cantilevered staircase rises through the centre of the house, linking a sequence of rooms made for entertaining — a reception with herringbone floors and a Regency fireplace, a dining area with a Persian Palissandro Bluette marble bar, and a club room that doubles as a cinema with a cocktail bar, wine cellar and deep green joinery.

 

The kitchen pairs honed Calacatta and Paonazzo marble with warm timber cabinetry and Wolf, Gaggenau and Sub-Zero appliances. It connects naturally with the family room and terraces beyond, where glass doors run the length of the building.

 
The first floor is devoted to the principal suite, once Fonteyn’s own, with twin dressing rooms, a marble bathroom and Juliet balconies overlooking the garden. The second floor houses the guest suite, formerly Fonteyn’s studio, while the penthouse opens onto a roof terrace with an outdoor kitchen and bar, with views towards the Victoria and Albert Museum.

 

The lower level is a private spa finished in travertine and filled with daylight. A 12-metre pool with waterfalls and a media screen sits beside a glass-walled gym, sauna, steam room, hot tub and treatment space. An ice fountain and relaxation area complete the retreat.

Outside, the walled garden and terraces form a series of outdoor rooms: a dining area beside a granite fireplace, raised lawns with a cinema screen, and a rooftop garden that offers complete privacy above the city.



Opposite the Victoria and Albert Museum, the house sits moments from the boutiques and restaurants of the King’s Road and Sloane Square, and within easy reach of South Kensington and Knightsbridge stations. Hyde Park is a short walk away, with Battersea Park just over a mile across the river.

Set on one of Chelsea’s most desirable streets, moments from the King’s Road, this remarkable six-bedroom home spans six floors and has been beautifully reconfigured to maximise natural light and space. The property offers six bathrooms and three additional WCs, providing exceptional convenience for a house of this scale.

Completed in 2016, the renovation introduced underfloor heating throughout and comprehensive security, while interiors were entrusted to Axel Vervoordt. Known internationally for his eponymous gallery, Vervoordt has imbued the house with his signature aesthetic: natural materials, refined proportions, and bespoke pieces that blur the line between furniture and art.

Inside, the tone is set by stone fireplaces in the entertaining rooms and a professional-grade Boffi kitchen, fitted with two oversized Sub-Zero refrigerators, additional freezer space, a wine cellar, and Gaggenau appliances beneath a dramatic commercial hood. The principal reception rooms are both voluminous and light-filled, their gallery-quality lighting calibrated for displaying art.

Accommodation is versatile, with six bedrooms and six bathrooms arranged across the upper floors. At basement level, an independent suite with its own kitchenette and two bathrooms provides privacy for guests or staff. The lower ground also houses a sound-proofed projection room seating ten, a home gym with ballet barre and steam shower, and a climate-controlled wine vault with capacity for two hundred bottles.

Outdoor spaces are equally considered. The house itself has a rooftop garden planted with mature trees and shrubs, served by an automated irrigation system and complete with a built-in barbecue. There is access to the gated communal garden of Ormonde Gate, as well as membership to the adjoining Burton Court gardens and tennis courts, a rare privilege in Chelsea, particularly prized by dog-owners.

Security and practicality underpin the sense of ease: CCTV, police-linked panic buttons on every floor and a functioning alarm system are all in place.

Ormonde Gate occupies a prestigious residential pocket of Chelsea, where handsome red-brick houses and apartments line tree-shaded streets. From here, the King’s Road unfolds with its blend of designer boutiques, cafés and restaurants, while Sloane Square and the Saatchi Gallery are a short walk away.

This expansive Grade II-listed white stucco villa in the heart of Little Venice spans 7,362 sq. ft. and offers an exceptional lateral living layout – a rarity in the area. There is also planning permission to extend the residence’s lateral footprint across two buildings and reconfigure various areas of the property, presenting a promising development opportunity.

 

An original Portland stone staircase forms the heart of the residence. The grand drawing room boasts lofty proportions and ornate cornices with wooden floors running underfoot. A large open-plan kitchen and family room sit adjacent. A 105-foot south-west-facing rear garden, accessible from the kitchen and reception, extends the living area outdoors.

 

The principal suite unfolds over the first floor, complete with two dressing rooms and additional storage. It is flanked by a discreet study with an ensuite bathroom, providing a peaceful retreat ideal for working from home. The remaining four bedrooms, two of which are ensuite, occupy the second floor. A further dine-in kitchen and family bathroom are also located on this level.

 

The entirety of the lower ground floor is dedicated to another reception, which can serve as a games room or TV room. A laundry room, cloakroom and pantry complete the offering.
