Stirling Square, St James, London, SW1Y

Occupying the sixth and seventh floors of Stirling Square, this exceptional three-bedroom duplex penthouse sits moments from The Mall in the heart of St James’s. Designed by the celebrated British architect Sir James Stirling, the building remains one of the area’s most architecturally significant residential addresses and the final legacy of one of Britain’s most influential post-war architects.



The apartment has been the subject of a meticulous refurbishment throughout, resulting in a turnkey residence of exceptional quality and finish. Spanning approximately 2,567 sq ft, the interiors combine refined contemporary design with generous proportions and excellent natural light, creating a calm and highly considered living environment.



The principal reception room is a striking space with expansive windows framing far-reaching views across St James’s Palace and the surrounding historic skyline. High ceilings, bespoke joinery and carefully selected materials create a polished yet understated atmosphere throughout.



The bespoke kitchen has been beautifully designed with handcrafted cabinetry, premium stone surfaces and fully integrated appliances, offering a practical layout equally suited to entertaining and everyday living. A separate utility room sits discreetly alongside.



Bedroom accommodation is arranged across the lower floor to provide a strong sense of privacy. The principal suite features a luxurious ensuite bathroom, while two further bedrooms each benefit from their own ensuite shower room. A guest WC completes the accommodation. All bathrooms have been finished to an exacting standard with marble surfaces, bespoke fittings and high-quality materials throughout.



A substantial private roof terrace provides an elegant outdoor entertaining space with rooftop views across St James’s, while residents also enjoy access to beautifully maintained communal gardens below.

Additional features include air conditioning, lift access, underground parking, 24-hour concierge and security, and comprehensive CCTV throughout the building.



Positioned between The Mall and Pall Mall, Carlton Gardens is one of Central London’s most discreet and sought-after addresses, moments from St James’s Park, Green Park and the amenities of Mayfair. Michelin-starred restaurants, private members’ clubs, galleries and luxury boutiques are all within easy walking distance, placing some of London’s finest cultural and lifestyle destinations on the doorstep.
