About this property

Marylebone Square is one of London's most sought after locations comprising 54 private lateral apartments located within a beautifully designed mixed use building. Marylebone Square is a rare opportunity to be part of the provenance of aristocratic estates in Central London.

A contemporary take on a classic London mansion, it is an intuitively designed building that slots into the urban fabric of Marylebone. Set over five floors, Marylebone Square houses just 54 one to three bedroom apartments. All apartments have been designed from a central atrium which is the centrepiece of the building and allows for every apartment to have dual aspect.

The agent hasn't said which band this home is in; you can look it up on GOV.UK. In Westminster, 2026/27 bills run from £700 a year in band A to £2,099 in band H.

Figures from MHCLG (Open Government Licence v3): the average bill for each band across Westminster, including the typical parish precept, so a parish's own bill can differ a little. Discounts lower the bill, such as 25% off for an adult living alone.
