About
Elegant 1 bed + study, 899 sq ft on 3rd floor with balcony. Completed home in the heart of Marylebone, blending style, space and prime central London living.
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.
