Grosvenor Britain & Ireland has submitted a planning application for the South Molton Triangle, with a vision to transform this historic and underused part of North Mayfair.

The two-acre area, which is home to Grays Antiques, encompasses a number of narrow side streets and neglected buildings. It is bounded by South Molton Street and Davies Street and lies immediately opposite the new Elizabeth Line Bond Street West station.

It is hoped that the development would breathe new life into this space by introducing new offices, homes (22 open market and 11 affordable) and a 31-bed hotel, with the installation of wide pedestrian-friendly routes, al fresco dining and public spaces. New shops, restaurants and cafes would provide a range of services to residents and the wider Oxford Street district. The designs celebrate the townscape’s existing silhouette and the special character of the Mayfair Conservation Area by retaining and adapting historic buildings for contemporary use.

Thomasin Renshaw, Director of Development, Grosvenor Britain & Ireland said: “Our proposals for the South Molton Triangle are a sign of our significant confidence in, and commitment to, the future of the West End and Oxford Street district. These designs put pedestrians first in a sustainable scheme that preserves what’s great about Mayfair while bringing the jobs and investment London now needs to see.”

Grosvenor’s environmental goals include achieving net zero carbon, zero waste by 2030 and delivering a significant biodiversity gain.

The Triangle’s new buildings will produce 35% less carbon than ones built to current UK standards, while servicing would only be by electric vehicle, reducing on street pollution and traffic. 250 bike spaces for office workers, and 50 on-street spaces will also encourage sustainable modes of transport. Grosvenor is greening the area, planting more trees.

The designs were created by Marylebone-based Hopkins Architects – and Donald Insall Associates advised on the retention and adaptation of the historic buildings.
