We've tightened what earns a Pursue. A home now needs a published valuation, a strategy that still makes money after real running costs and lender stress tests, and no listing problems that would stop a mortgage. You'll see fewer Pursues, and each one has been checked harder.

About
Description Occupying a high floor within one of Mayfair's most impeccably serviced residential buildings, this Four Seasons-managed lateral apartment offers 3,317 sq ft of elegant, hotel-style living at the heart of Grosvenor Square.
Designed for effortless comfort and privacy, it combines generous proportions and a thoughtful finish, making it particularly appealing to international buyers seeking a turnkey London base with full concierge support.
The apartment is entered via a beautiful central hallway that sets the tone for the scale and symmetry throughout.
To one side lies the principal reception space, an impressive dining and living room extending to over 33 feet in length.
Finished with polished stone and hardwood flooring, comfort cooling and underfloor heating, this is an elegant room designed for entertaining as much as daily life, with excellent ceiling height.
A separate kitchen and breakfast room sits just beyond, fitted with sleek contemporary cabinetry and a full suite of integrated appliances as well as plenty of space for dining; a utility room and plant room are positioned separately.
The bedroom accommodation is quietly impressive.
The principal suite is exceptionally generous, arranged with a dedicated dressing room and a large ensuite bathroom finished with Dornbracht and Duravit fittings.
Three further double bedrooms are all well-proportioned, each served by high-quality ensuite bathrooms, ensuring excellent privacy and flexibility for guests or family.
Throughout the apartment, a Lutron lighting system and amx smart home automation underline the level of specification, while the interiors remain timeless and restrained.
Residents benefit from 24-hour concierge services and access to extensive leisure facilities located within the building, including a fully equipped gym, swimming pool, private cinema, sauna and steam rooms.
Security is discreet yet comprehensive, with a private gated entrance and hotel-style management offering a rare sense of ease in central London.
Grosvenor Square remains one of the capital’s most prestigious addresses, moments from the boutiques and restaurants of Mount Street and the wider Grosvenor Estate.
The square itself is entering a new era, shaped by the transformation of the former us Embassy into the Rosewood hotel, bringing a renewed sense of glamour to the neighbourhood.
Famous for its historic architecture, exceptional privacy and a growing collection of destination restaurants, this corner of Mayfair, is one of London’s most enduringly desirable places to live.
