Description

Marylebone Square is a rare opportunity to be part of the legacy of aristocratic estates in Central London. A contemporary take on a classic London mansion, it is an intuitively designed building that integrates seamlessly into the urban fabric of Marylebone.

Set over five floors, Marylebone Square houses just 54 one- to three-bedroom lateral apartments. All apartments have been designed around a central atrium, which is the centrepiece of the building and allows every apartment to have a dual aspect.

The residences are refined, elegant, and intuitively designed; each apartment is generously spacious yet warmly intimate.

Created by developers Concord London and Simon Bowden Architects, all residences benefit from floor-to-ceiling windows and sliding glass doors, giving each space a bright and expansive feel. Additional features include a 24-hour concierge service.

Marylebone Square complies with a 10-year build warranty by NHBC.

Location

With more charm than Fitzrovia and greater diversity than Mayfair, it has long possessed a character all its own. Its proximity to Oxford Street and Regent’s Park contrasts beautifully with its leafy streets and village-like intimacy.

At Marylebone Square, you're perfectly placed. Paddington, Marylebone, and Baker Street stations are all within easy reach, while Bond Street Underground - served by the Elizabeth line - offers direct connections to Heathrow and beyond.

For entertainment, hail a cab to the Royal Opera House or London’s West End, or simply stroll over to Selfridges for world-class shopping.

Square Footage: 1,399 sq ft
Leasehold with approximately 991 years remaining.
