A dramatic duplex penthouse in the heart of Mayfair, spanning approximately 2,027 sq ft and finished to a contemporary luxury standard. Interiors were newly developed in collaboration with 1508, combining original 1849 period details and modern fittings including underfloor heating, comfort cooling and a high‑pressure hot water system. The accommodation includes three bedrooms and three bathrooms, organised over generous lateral living space with a spiral feature staircase and lift access.
The apartment’s private roof terrace offers rare outdoor space for central London living and adds useful entertaining and relaxation potential. Building services include concierge and secure access. The 999‑year lease gives long‑term security while the newly completed development status means minimal immediate maintenance is expected.
Considerations: this is a high‑value Mayfair home in a very central, lively neighbourhood; prices and living activity reflect that prime location. Crime levels are reported as very high for the immediate area—buyers should allow for enhanced security measures and insurance costs. The property is leasehold and offered at a premium price point, suitable for purchasers seeking a central luxury pied‑à‑terre or primary residence in Mayfair.
Overall, Six Charles Street will suit someone seeking a stylish, move‑in ready penthouse with heritage character, generous internal space and outdoor terrace, who accepts the practicalities and costs of central London living.
