Only a few penthouses in Marylebone combine uninterrupted south and east-facing views, exceptional lateral living and a prime Portman Square address quite like this. Occupying one of the most enviable positions overlooking Portman Square, this beautifully crafted residence has been extensively refurbished and interior designed by the award-winning Base Interior. The south and east facing terrace is one of the stand out features of the home.

Spanning approximately 1,900 sq ft (177 sq m), the apartment occupies the seventh floor of the prestigious Fitzhardinge House, a highly sought-after 24-hour portered building. Every aspect of the home has been meticulously considered, creating elegant interiors that are perfectly suited to both modern living and sophisticated entertaining. The property also benefits from a secure underground parking space and a private storage room.

Fitzhardinge House occupies a prime position on the north side of Portman Square, moments from Selfridges, Marylebone High Street, Oxford Street and the open green spaces of Hyde Park.

Residents enjoy exclusive access to Portman Square's private gardens and floodlit tennis court, while Bond Street and Marble Arch stations provide exceptional connectivity across London.
