Summary - SECOND FLOOR AND THIRD FLOOR MAISONETTE, 17 UPPER GROSVENOR STREET W1K 7PN
3 bed 3 bath Apartment
Duplex Mayfair apartment with terraces, private lift and extensive entertaining space near Hyde Park.
Approximately 3,359 sq ft across two floors, dramatic entertaining spaces
A substantial three-bedroom duplex in the heart of Mayfair, occupying the second and third floors of a handsome Georgian townhouse. At approximately 3,359 sq ft this apartment delivers grand entertaining rooms, a formal dining space, and direct private lift access to the main living floor. Two terraces — one off the entertaining level and one off the principal suite — extend living outdoors in central London.
High-spec fixtures and technology include underfloor heating, Lutron lighting, CCTV, air conditioning and a bespoke glass staircase. The principal suite has an extensive walk-in wardrobe and a private steam room. A live-in caretaker and building stone-clad façade add convenience and presence; ancillary amenities include an on-site gym.
Important practical points: the property is leasehold with 103 years remaining and is served by mains gas boilers with radiators alongside the underfloor heating. The building dates from 1900–1929 and has solid brick walls appearing to lack built-in insulation; double glazing is present but installation dates are not specified. Council tax is very expensive and the local crime statistic is very high — both factors to consider for running costs and security planning.
This apartment suits an owner-occupier seeking a large, characterful Mayfair base with significant entertaining space, or an investor seeking a high-value central London asset. Buyers should factor potential thermal upgrading and the leasehold position into their budgeting and long-term plans.
