When your entry-level apartment is 35 million GBP, you’re in a next-level tier of wealth. Some would even say “royal.” So, it’s no surprise that The Dorchester, owned by the Sultan of Brunei, is set to look after one of the most luxurious places to live in the world. Welcome home to the new 1 Mayfair Dorchester Collection residences London.
The new landmark in Mayfair’s most prestigious address is a meaningful expansion for a brand that defines a very specific kind of life. Now, Dorchester Collection will manage 1 Mayfair. This is luxury property developer Caudwell’s £2 billion ultra-prime residential development on South Audley Street. Notably, the project is expected to complete in Q1 2027.
Set near Park Lane and Hyde Park, 1 Mayfair brings 24 meticulously designed residences, five staff suites, entertainment halls and lounges, each looking over a central garden. Residences include penthouses, apartments, pieds-a-terre, and townhouses. From the Crystal Gallery with hand-cast glass pieces to hand-painted frescoes in the main rotunda, it’s all about spaciousness and modern luxury. Meanwhile, prices are expected to start at £35 million.
But the true luxury here will be the service.
The Service
This is where One Mayfair Dorchester Collection becomes especially compelling: residents will receive luxury services by The Dorchester. This includes 24-hour security, concierge, valet parking, housekeeping, in-residence dining, and private chef access. In addition, priority reservations and services at The Dorchester, just a three-minute walk away, add another layer of appeal.
The Design and Amenities
The design pedigree is equally strong. Robert A.M. Stern Architects leads the architecture, while J.P. Molyneux Studio shapes the interiors. At the same time, amenities will include a health spa, 20-meter swimming pool, gym, treatment rooms, basement parking, a central garden, and private entertainment spaces. As a result, buyers are not simply purchasing square footage. Rather, they are securing one of Mayfair’s most fully serviced residences.
Coming Soon
Sales are expected to launch in 2026, when the first residence is due to be unveiled. Until then, 1 Mayfair offers a clear signal where Dorchester Collection London is heading next: beyond hospitality and into an extension of its signature way of life.
