This expansive duplex occupies over 2,900 sq ft in a secluded Edwardian mansion block just behind Baker Street. A private entrance and porter provide discreet, London townhouse-style living while the accommodation flows over two floors with high ceilings and generous room proportions.

The apartment has been meticulously refurbished throughout and offers four double bedrooms, a master suite with walk-in wardrobe and en-suite, two further reception rooms, dining room and a large lower-level kitchen with dumbwaiter — a strong layout for family living and entertaining. Modern fixtures, a contemporary primary kitchen and double glazing help complete the upgrade.

Practical strengths include a share of freehold, an exceptionally long lease (962 years) and immediate access to Baker Street transport links, Marylebone High Street shops, Waitrose and Regent’s Park. Nearby schools include several rated outstanding, making the location attractive for families.

Material considerations are clear and should be factored into any decision: the verified annual service charge is high at £20,772 and council tax banding is very expensive. The property sits in a high-crime inner-city area and the building’s solid-brick construction likely lacks modern cavity insulation. There are two bathrooms for four double bedrooms, which may require planning for larger families.
