The South Molton Triangle is a new redevelopment proposal by Grosvenor Britain and Ireland to transform a prime, but underutilised, Mayfair area into a high-end retail, office and leisure community. The scheme centres around the adaptable re-use of existing listed buildings and includes two new office buildings carefully set behind existing facades. The site covers 2 acres within the Mayfair Conservation Area and is part of the Grosvenor Estate.

South Molton Triangle sits adjacent Oxford Street and Bond Street and currently acts as a gateway into Mayfair from the north, with the new Elizabeth Line at Bond Street creating an additional arrival point and delivering large numbers of additional visitors to the area.

Two proposed new office buildings will provide approximately 150,000 sq. ft. of prime office space combined with 58,000 sq. ft. of new shops, restaurants and cafes. Office buildings are designed to meet BREEAM Outstanding and WELL Platinum standards, and are set to achieve a 35% improvement over the current Part L requirements.  

The development will also include a new boutique hotel, a conversion of four Grade II listed town houses facing Brook Street, with a destination restaurant and bar. A row of listed Georgian buildings along South Molton Street, will be converted from office use back to residential use, providing both private and affordable housing within the scheme. 

The scheme includes ambitious public realm provision to create a new identity for this unique area. Bespoke paving and landscaping will transform Davies Mews into a new al-fresco dining space. South Molton Lane, currently an underused back street, will be transformed with new micro retail units providing active street frontage. An emerging public art strategy aimed at celebrating the River Tyburn that flows beneath the site, will be incorporated within the public spaces.
