About this property
Floor-to-ceiling windows frame a leafy park-facing outlook from this substantial four-bedroom duplex at One Hyde Park. Arranged across the ground and first floors, the apartment extends to approximately 4,419 sq ft (411 sq m) and offers the privacy and proportions of a London house alongside the security and service of One Hyde Park. Separate entertaining and bedroom levels, a full-width landscaped garden and a second terrace make the residence particularly rare, both within the development and across prime central London.

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.
