Ultraluxe: new Marylebone flats give Mayfair a run for its money with Bentley house car and Fortnums groceries

Marylebone has never been in quite the same price league as Mayfair, but The Mansion, a smart new-build scheme of 23 flats with luxury amenities, aims to usurp the super-rich enclave on the other side of Oxford St.

Architect DSDHA’s elegantly designed building in Marylebone Lane reflects that street’s gentle curve and picks up on the area’s handsome red-brick mansion blocks by using terracotta fins on the largely glass façade.

Developer Clivedale has taken creature comforts a step further, with a Bentley house car for drop-off and pick-up services within central London, while Fortnum & Mason will deliver groceries.

Jeeves of Belgravia is handling dry cleaning and Bamford will arrange treatments in the basement spa with 25-metre private pool.

A 24/7 concierge will attend to other requests.

Prices from £4.85 million. Call CBRE on 020 7182 2477.
