Set above Marylebone Square, The Rossetti Penthouse is an exceptional three-bedroom residence offering an extraordinary combination of space, design and private outdoor living in the heart of central London.

Extending to approximately 3,671 sq ft internally, the penthouse has been conceived as a sophisticated contemporary home, with three beautifully appointed bedrooms and three bathrooms complemented by generous living and entertaining spaces. At its heart is a sense of volume and light, with carefully considered interiors creating a calm and elegant environment above one of London’s most distinctive new neighbourhoods.

The property’s defining feature is its remarkable 1,386 sq ft private terrace. Providing an unusually generous amount of outdoor space for a central London residence, it creates a natural extension of the interior and an exceptional setting for entertaining, dining or simply enjoying a quieter perspective on the city.

The penthouse also benefits from two dedicated electric vehicle parking bays, adding a rare level of convenience to life in central London.

Marylebone Square brings together the character and intimacy of the surrounding neighbourhood with the advantages of a newly created address. With Marylebone High Street, independent boutiques, restaurants and cultural institutions all close at hand, the penthouse offers a distinctive London lifestyle, combining privacy and space with the energy of one of the capital’s most sought-after districts.

Transport connections are equally impressive. Baker Street and Regent’s Park Underground stations are within easy walking distance, providing access to multiple Underground lines, while Marylebone mainline station offers direct rail connections beyond central London. Bond Street is also close by, with Central, Jubilee and Elizabeth line services providing swift connections across London and onwards to Heathrow Airport.
