Key feature
A once-in-a-generation opportunity: the only new-build development to emerge from the heart of Marylebone in over a decade, occupying a rare unclaimed tract of land between two of London’s most storied private estates. Designed by Simon Bowden Architecture with interiors by LIV Interiors, Marylebone Square is a contemporary interpretation of the classic London mansion block — built from glazed terracotta and hand-crafted cast metal, centred around a breathtaking five-level glass-canopied courtyard.
- Central London's Sole New Build: Set between the Portman Estate and the Howard de Walden Estate, this site lay untouched for over five decades — a genuinely unrepeatable position in the fabric of W1
- The Glass-Canopied Courtyard: A five-level indoor garden with panoramic glazed lifts, a central pond, manicured birch trees and natural light flooding every apartment from both sides — the defining architectural feature of the development
- Dual-Aspect Every Home: Every one of the 54 residences is designed around the central atrium, ensuring natural light and air on both aspects — an architectural rarity in Central London apartment living
- Glazed Terracotta & Cast Metal: The exterior is a rich palette of glazed terracotta with intricate cast-metal balustrades and a signature lantern frieze inspired by Marylebone's celebrated connection with music and the performing arts
- 12 Penthouses with Private Terraces: The penthouse collection crowns the building with generous terraces, a signature lantern frieze and uninterrupted rooftop views across Marylebone
- 999-Year Leasehold: 24-hour concierge, secure underground parking, porter services and curated boutiques and restaurants at ground level — a complete, self-contained address in the very heart of W1
For five decades, this ground lay untouched at the heart of Marylebone. 54 luxury residences — Central London's only new build on once-noble land between the Portman and Howard de Walden Estates.

About this property
Marylebone Square occupies a site that, in London terms, simply should not exist: an unclaimed parcel of land at the heart of W1, between the Portman and Howard de Walden Estates, left untouched for over fifty years. Developed by Concord London and designed by Simon Bowden Architecture, the building is a sensitive yet contemporary addition to Marylebone’s celebrated Georgian streetscape — its glazed terracotta façade and hand-crafted cast-metal balustrades reading as a natural extension of the district’s architectural character. Inside, 54 residences from 1 to 3 bedrooms — and 12 penthouses — are arranged around a five-level glass-canopied central atrium, with floor-to-ceiling windows, oak flooring, French marble kitchens and bathrooms, and walnut veneer vanity units throughout. Ready to move in.
Local Area
Marylebone is one of London’s most quietly refined villages — a neighbourhood of independent bookshops, artisan food markets, acclaimed restaurants and independent boutiques, centred on Marylebone High Street and Lane. Regent’s Park and its open-air theatre are a short walk away, as are Selfridges and the full retail sweep of Bond Street. For connectivity, the development is moments from Marylebone, Baker Street and Bond Street stations — the last offering direct Elizabeth line access to Paddington, the City and Heathrow within minutes.

Investment
Marylebone Square is, by definition, a one-off. The site it occupies had not been developed for over fifty years and sits between two of London’s most protective private estates — making any comparable future development virtually impossible. The W1U postcode, the 999-year leasehold, and the building’s position at the centre of one of London’s most consistently demanded residential villages combine to make this a genuinely irreplaceable asset. For buyers seeking a trophy W1 address with long-term scarcity value and immediate lifestyle utility, further investment detail is available on request.
