One Hyde Park

A 999 year underlease of a named apartment. The building sits under a Superior Lease dated 30 November 2006 with a 999 year term, and each apartment is held by its tenant under a 999 year underlease beneath it. One Hyde Park Limited is the freeholder and superior landlord, having taken the freehold from the developer Project Grande (Guernsey) Limited on 11 June 2014, and 1 HP (Guernsey) LLC holds the residential demise as intermediate landlord. Land Registry records every apartment here as leasehold. Parking spaces and basement storage rooms are separate leasehold titles, bought and sold on their own.

There are no fixed weeks and no allocated time. An owner uses the apartment whenever they wish, within the terms of the underlease. In Greater London, using 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, under section 44 of the Deregulation Act 2015. Whether the underlease permits letting at all is confirmed for the specific residence before you commit. Avory arranges stays in owner apartments where the owner allows it, subject to availability.

One Hyde Park Limited provides the building services under Schedule 4 of the Superior Lease and recovers the cost from the apartments. The figure is not published, so it is confirmed for the specific residence before you commit. Ask about the chilled water pipework at the same time. In February 2026 the High Court found pervasive corrosion through it and awarded the freeholder £34,437,122.60 for its replacement against the contractor, Laing O'Rourke Construction South Limited, which had gone into liquidation. The work is estimated at around 10 years, done floor by floor, with the apartments on a floor vacated while that floor is worked on. Council tax is payable to Westminster City Council.

A full-time team trained by Mandarin Oriental runs the building, with a 24-hour concierge, valet, housekeeping, maintenance and security. Residents have signing privileges at the Mandarin Oriental Hyde Park next door and 24-hour in-residence dining from its kitchens. The leisure, entertaining and meeting rooms are held in common with the other apartments and are listed below.

Rogers Stirk Harbour + Partners designed it, with Graham Stirk leading the team. Candy & Candy did the interiors and managed the development for Project Grande (Guernsey) Limited, a joint venture between CPC Group and Sheikh Hamad bin Jassim bin Jaber Al Thani. Laing O'Rourke built it and Arup engineered the structure. Practical completion was on or about 20 January 2011. Four pavilions, designated A to D, stand on five cores behind pre-patinated copper alloy screens on a pre-cast concrete frame. Two basement levels hold 139 car spaces and 114 cycle spaces. Apartments on the energy certificate register run from 79 sq m (850 sq ft) to 2,242 sq m (24,100 sq ft).

The building stands on the north side of Knightsbridge, in the City of Westminster, at the top of Sloane Street, with Hyde Park directly across the road. Mandarin Oriental describes the setting as lying between the park and the Knightsbridge shopping streets. Three retail units of about 9,000 sq ft sit at street level beneath the pavilions, and the Mandarin Oriental Hyde Park hotel is next door. The postal address is 100 Knightsbridge, SW1X 7LJ, in the Knightsbridge and Belgravia ward.

A buyer from abroad follows the same conveyancing route as a UK buyer, with three extra costs to plan for. Stamp duty land tax reaches 12% on the slice above £1,500,000, with 5% on top if you will own another dwelling anywhere, and a further 2% where a buyer is not UK resident. An overseas company must be on the Companies House Register of Overseas Entities, with its beneficial owners named, before its purchase can be registered at HM Land Registry. A company-held apartment also pays the annual tax on enveloped dwellings. Your solicitor confirms the figures for your own case.

Resale apartments here trade privately. Avory works through the agents who hold them and, where an owner is willing, direct with the owner or their solicitor. After you enquire we confirm what is genuinely available, then get the size, tenure, service charge and pipework position from the managing agent in writing, and arrange a viewing. We cannot sign you into the hotel's resident services, and owner stays depend on that owner, subject to availability. Request access.
