Portman Square, Marylebone, London, W1H

A wraparound roof terrace and far-reaching views across two of London’s finest garden squares distinguish this three-bedroom penthouse on Portman Square. Found on the seventh floor of Fitzhardinge House, the double-aspect apartment spans approximately 1,907 sq ft and has been redesigned by Base Interior, with generous lateral proportions, underground parking and access to the square’s private gardens.



At the heart of the apartment is an impressive dining and reception room measuring almost 30 ft in length. Full-height glazing draws the outlook into the interiors, while doors open directly onto the terrace, allowing the living space to extend outdoors. The terrace continues around two sides of the apartment, looking south across the treetops of Portman Square and east towards Manchester Square.



A separate kitchen and breakfast room adjoins the reception space. Dark timber cabinetry is paired with pale worktops and integrated Gaggenau appliances, while a window above the sink brings in natural light. The dining area is arranged beside the reception room, creating an excellent flow for entertaining while keeping the kitchen discreetly separate.



The principal bedroom is particularly spacious, with extensive fitted wardrobes and doors onto the terrace. Two further double bedrooms also feature built-in storage, and one has direct access to the outdoor space. There are three beautifully finished bathrooms, two of which are ensuite, where book-matched stone, marble and dark cabinetry introduce depth and character.



Air conditioning runs throughout the apartment. Residents of Fitzhardinge House also benefit from a lift, 24-hour concierge service and a private underground parking space.



Portman Square is one of Marylebone’s most sought-after addresses, arranged around mature private gardens with a floodlit tennis court available for residents’ use. Selfridges and the shops of Oxford Street are moments away, while the independent boutiques, restaurants and cafés of Marylebone High Street are also within easy reach. Hyde Park lies a short walk to the south, with transport connections available from Bond Street and Marble Arch underground stations.
