Grosvenor Britain & Ireland has submitted a planning application for the redevelopment of the South Molton Triangle in Mayfair.

The scheme will create 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 support the townscape’s existing silhouette and the character of the Mayfair Conservation Area by retaining and adapting historic buildings for contemporary use.

The 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 commented: “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 will 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.

* 33 homes are proposed within the designs – 22 open market homes and 11 affordable homes (35% by area and habitable room of on site affordable)
