South Molton Triangle’s pedestrian first proposals to help reboot the West End

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

  • New employment, retail and dining spaces will be framed by pedestrian friendly routes in the heart of London’s West End
  • Sensitive design celebrates historic area’s architectural character and adapts heritage buildings for contemporary use
  • Sustainable buildings to produce 35% less carbon than ones built to current standards; scheme to be serviced by all-electric vehicles

Covering 2 acres this area, well-known as the home of 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.

The Triangle would breathe new life into this space by introducing new offices, homes* and a 31-bed hotel framed by wide pedestrian friendly routes 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.

These proposals will also help the area bounce back from Covid-19, providing 204,000 sq ft of new Grade A office space, alongside 67,500 sq ft of shops, restaurants and cafes, supporting over 700 new jobs once complete and attracting an estimated spend of £6 million per year.

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.”

All Grosvenor’s projects work to a series of bold environmental goals including achieving net zero carbon, zero waste by 2030  and delivering a significant biodiversity gain.

The Triangle’s new buildings would produce 35% less carbon than ones built to current UK standards. Servicing would only be by electric vehicle, reducing on street pollution and traffic around the already pedestrian friendly scheme. 250 bike spaces for office workers, and new 50 on street spaces, will also encourage sustainable modes of transport in the area. The site, which currently only hosts one tree, will benefit from new trees and increased greening.

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