Lying on the second floor of the handsome red-brick Basil Mansions, this beautifully refurbished lateral apartment unfolds across almost 2,500 sq ft and pairs generous proportions with elegant contemporary finishes. Positioned moments from Harrods and the boutiques of Knightsbridge, the building offers the comfort of a porter and lift, while the apartment itself has been comprehensively renovated by the current owners to an exacting standard.



The layout is particularly well balanced for both entertaining and everyday life. At the front of the apartment, a magnificent reception room extends across the curve of the building, its wide bay window drawing in natural light and opening onto a private balcony. The room connects to a generous dining room, creating a suite of reception spaces that can be used formally or informally. A second reception room sits beyond, offering a more intimate sitting room or television room.



The kitchen is arranged separately and has been fitted with bespoke cabinetry and integrated appliances, centred around a large island and complemented by a built-in seating area. Discreet storage and a guest cloakroom sit just off the entrance hall.



The sleeping accommodation is arranged along the other side of the apartment. The principal bedroom occupies a striking corner position with a large bay window and extensive built-in wardrobes, served by an ensuite bathroom with freestanding bath and separate marble-lined shower. Two further double bedrooms are well proportioned and share a beautifully finished family bathroom, while a fourth room currently configured as a study could easily serve as an additional bedroom if required.



Basil Mansions is a distinguished Edwardian mansion block set on Basil Street, a short walk from the open green spaces of Hyde Park. Knightsbridge remains one of London’s most coveted neighbourhoods, defined by its grand architecture and exceptional amenities. World-class shopping at Harrods and Harvey Nichols sits moments away, alongside a host of celebrated restaurants, cafés and galleries. Excellent transport connections can be found at Knightsbridge Underground Station (Piccadilly Line), providing swift access across the capital.
