Twenty Grosvenor Square, Four Seasons Private Residences

A long leasehold apartment, with the rights that come with it to the shared amenities and to the Four Seasons services in the building. Savills particulars for a five-bedroom residence here quoted a lease with approximately 922 years remaining, so these are long-dated leases rather than short ones. What transfers on completion is that lease and the schedule of rights attached to it. Four Seasons manages the building and does not own or sell the apartments. The exact term, the ground rent and any share of the freehold are confirmed for the specific residence before you commit.

Owner use all year, with no fixed weeks and no allocation system, because this is whole ownership rather than a fraction or a club membership. There is no hotel in the building, so there is no operator rental programme to place an apartment into. Any letting is arranged privately and sits inside the terms of your lease and the house rules. In Greater London, use of a home as temporary sleeping accommodation for more than 90 nights in a calendar year is a material change of use and needs planning permission. Avory arranges stays in owner residences, subject to availability.

The service charge pays for Four Seasons as property manager, the designated Director of Residences, 24-hour concierge and security, housekeeping of the common areas, the spa, pool and fitness centre, and building maintenance. Neither Four Seasons nor Finchatton publishes a rate, so the charge is confirmed for the specific residence before you commit. Council tax in Westminster is 2,095.70 GBP at band H for 2026/27. Where an apartment is held through a company, the annual tax on enveloped dwellings is 151,450 GBP on a value of 10 million to 20 million GBP and 303,450 GBP above that, for 2026/27.

Four Seasons runs the building rather than only the front door. It acts as property manager, with a designated Director of Residences as the point of contact, and the team on site covers concierge, security monitoring, housekeeping, catering and in-residence dining. The spa, pool, gym, cinema, wine cellar, garden library, business suite, games room and creche are all inside the building, as is the car park with valet parking. The list below sets out what is on site and what the team handles.

A redevelopment of the former European headquarters of the US Navy, the building General Eisenhower used for D-Day planning in 1943. Consent kept the classical Italianate facade and allowed the rest to be rebuilt, with a further floor added. Squire & Partners set contemporary pilasters, fluted stone, projecting bay windows, linear balconies, patterned metalwork and a slate-clad stepped mansard into brick, glass, stone and metal. The scheme runs to 250,000 sq ft, completed in 2019, with a 26,000 sq ft car park below and a landscaped courtyard garden inside.

37 residences of three, four and five bedrooms, with interiors by Finchatton under design director Jiin Kim-Inoue. Savills particulars for one five-bedroom apartment gave a gross internal area of 5,775 sq ft, being 536.5 sq m, with a double reception room, five bedroom suites, a family kitchen and a separate professional kitchen, a dining room, a media room, a study and separate staff access. Finishes across the scheme include book-matched Italian marble, Loro Piana cashmere wall panels, De Gournay hand-painted silk wallpaper and Tai Ping silk rugs. Floor areas are confirmed for the specific residence.

The building stands on Grosvenor Square with a further frontage to North Audley Street, and rooms on the square side look over its garden. Savills gives Bond Street as the closest underground station, about 0.2 miles away, which puts the Elizabeth line and its Heathrow trains within that walk. The shops and restaurants of Mayfair and the West End sit in the same few streets, and 47 Park Street, the other Mayfair address Avory works with, is a short walk to the south.

An individual buying in their own name needs no licence in the United Kingdom. An overseas entity does have a process: it must be on the Register of Overseas Entities at Companies House before it can buy, sell, lease or charge property here, its beneficial owners must be verified by a UK regulated agent in the three months before it registers, and it must file an update statement every year after that. Stamp duty land tax reaches 12 per cent above 1.5 million GBP, with 5 per cent more on an additional dwelling and 2 per cent more for a non-resident buyer.

Avory works with the Mayfair agents who hold instructions in the building, with owners directly, and with the Four Seasons management office on site. After you enquire you receive what is actually available, with the lease term, the floor area and the service charge for each apartment in writing, a viewing, and an introduction to a conveyancing solicitor. Resales are sold by private owners, so a particular apartment is not always available, and owner stays are subject to availability. Request access.
