A thoughtfully arranged top-floor home set across two levels, offering three bedrooms and refined living in one of Mayfair’s most established settings.



Tucked away behind a distinguished Victorian mansion block, this recently refurbished duplex penthouse offers an exceptional standard of luxury in the heart of Mayfair Village. Spanning the fifth and sixth floors, the residence boasts refined interiors, elegant proportions, and a private terrace with leafy, treetop views.

Upon entering the apartment, an impressive feature staircase sets the tone for the home’s sophisticated aesthetic. Large sliding oak and glass doors lead to a spacious, open-plan reception and dining area, where soaring ceilings and expansive windows flood the space with natural light. A striking gold feature wall adds a touch of grandeur, enhancing the penthouse’s unique character.

The impeccably designed kitchen balances minimalism with functionality, offering a sleek marble island with integrated seating, a wine cooler, and top-of-the-line Gaggenau appliances, all framed by verdant outlooks. Also on this level, the principal suite provides a sanctuary of comfort, complete with extensive built-in storage and a luxurious ensuite bathroom finished in exquisite marble. A stylish guest WC completes the floor.

Ascending to the sixth floor, two additional generously sized en suite bedrooms feature bespoke built-in storage and refined detailing. A beautifully appointed private terrace offers a serene retreat above the city.

Residents of this exclusive building benefit from a 24-hour concierge service, ensuring security and convenience at all times. Positioned in the heart of Mayfair Village, this exceptional penthouse is moments from world-class dining, luxury retail, private members’ clubs, and the verdant expanse of Hyde Park.
