RX London The Ada Building, Mayfair

Managed by RX London, The Ada Building at 15 Berkeley Street sits in the heart of Mayfair, moments from Berkeley Square and Green Park. The building is a comprehensive Grade A refurbishment by architects Stiff + Trevillion, occupying a site historically home to the women-only Empress Club, purpose-built in 1887 and inaugurated by Queen Victoria.

The available space is 'The Penthouse', a self-contained suite spanning the brand-new 7th and 8th floors (approximately 1,200 sq ft) offered on a fully managed basis at £200 psf / £27,500 pcm. It benefits from its own expansive private rooftop terrace with panoramic skyline views across Mayfair and St James's, alongside access to a large communal roof terrace. Wider building features include a passenger lift, three showers, brand-new openable double-glazed windows, full-fibre 1GB connectivity and high-efficiency VRV heating and cooling, all delivered to a BREEAM Excellent / EPC A standard.

Green Park station (Jubilee, Piccadilly and Victoria lines) is around a 3-minute walk at the Piccadilly end of Berkeley Street, with Bond Street (Central and Elizabeth lines) roughly 11 minutes north and Piccadilly Circus (Piccadilly and Bakerloo lines) about 8 minutes east (walking times to verify). The immediate neighbourhood offers Mayfair's top-tier restaurants, private members' clubs and the luxury retail of Bond Street and Piccadilly.
