Mayfair · Park Lane & Mount Street
1 Mayfair
The residences
- The name licensed to this project and carried on the building. A brand is not a company: it holds no title, builds nothing and runs nothing.
- Dorchester Collection
- The business the brand comes from — hotel, fashion, design, automotive, restaurant, club, or a developer’s own name.
- Hotel
- How many separately titled homes this project sells, counting every kind it sells. Where it sells more than one kind, each is named and its own count given.
- 24+
- The kinds of home offered — villas, condos, penthouses, lots — and how they break down. Not how many, and not what interest is sold.
- lateral apartments, penthouses and townhouses of 3,000–16,000 sq ft, including two duplex penthouses and a triplex, beside five further units the sources variously call staff suites and pieds-à-terre
- Whether a hotel shares the site, the building is mixed-use, or it is residences only.
- Residences only, no hotel
- The published asking range or entry price.
- GBP from 35M
- When the project was first made public.
- No opened page states when the scheme was first made public. The architect's own project record and the building database carry no announcement date.
- When its residences were first released for sale.
- The trade report of the management appointment states the main sales phase begins in 2026 when the first residence is unveiled, without giving a release date.
- When ground was broken on the site.
- No opened page states when ground was broken. The developer's own release records the structure and basement complete at a topping out on 26 November 2024.
- Every handover date the project has been given, oldest first.
- 2026→2027
- When the residences were handed over to buyers.
- The building database records the scheme under construction, so no handover has occurred.

- Robert A.M. Stern Architects
- The practice or individual who designed the interiors.
- Molyneux Studiowritten Juan Pablo Molyneux in trade coverage and Molyneux Studio on the building database
