Proposals for the South Molton Triangle

Creating a new mixed-use development in Mayfair

The South Molton Triangle, bounded by Davies Street, Brook Street and South Molton Street covers 2 acres within the Mayfair Conservation Area.

The proposals for this area would create elegant, greener, welcoming streets, and more homes that are accessible to more people, while preserving what’s great about Mayfair.

The proposals would enhance the range of employment opportunities in Central London. The new offices combined with 58,000 sq ft of new shops, restaurants and cafes would create more than 750 jobs, including up to 80 apprenticeships during construction and c. 440 employment opportunities during each year of construction. The South Molton Triangle would also attract an estimated additional spend of £6 million per year, supporting existing businesses and helping the area bounce back from the challenges caused by Covid-19.

The proposals represent the culmination of nearly two years consultation and feedback on designs by Hopkins Architects, one of the great pioneers of British architecture over the last 40 years. We would celebrate the architectural variety and significance of Mayfair by sensitively adapting the historic buildings to enrich the conservation area.

Over the next few months, the team will progress the design, using local feedback to inform their approach. This will allow us to share the final proposals in early summer 2020 when we submit a planning application to Westminster City Council.

The proposals for the South Molton Triangle form part of Grosvenor’s broader commitment to the success of London, the West End and its estate. In 2017, Grosvenor published a 20 year vision for its Mayfair and Belgravia estate, detailing how it wanted to respond to help London tackle the many pressures it faces. Central to this was the evolution of the estate to be more active, open and integrated, providing better streets, greener spaces and enterprising places.
