We are leading construction of two new Category A office buildings, alongside retail and leisure space, as part of the wider mixed-use redevelopment of South Molton in Mayfair, London, for our customer Grosvenor and Mitsui Fudosan UK joint venture.

The project includes the demolition of existing buildings and the construction of two new office buildings at 60 Brook Street and 56 Davies Street, delivering 71,000 sq. ft and 78,000 sq. ft respectively. We are also restoring the Running Horse Pub, alongside ground floor retail, restaurants, cafés and a basement gym, bringing the total development to 267,000 sq. ft.

Our scope

In addition to the main construction works, we will deliver CAT A mechanical, electrical and public health (MEP) systems, including the site-wide data network, security and smart building solution. All phases of South Molton are on track to complete in July 2027.

Collaboration and sustainability

We have been working with the Grosvenor and Mitsui Fudosan UK JV since October 2022 to evolve the design and construction methodology for South Molton, including identifying sustainability and carbon reduction strategies.

This approach has reduced steel usage by 200 tonnes, with the re-use of existing steel elements, pre-fabrication of façades and in-situ construction of the concrete base slab all contributing to lower carbon emissions.

Building features

The offices will offer world-class design and facilities, including large modern floorplates, roof terraces, outstanding amenities and strong environmental credentials. At ground level, they will be activated by a dynamic mix of retail and food and beverage outlets, together with attractive, greener streets.

Designed to complement the distinctive character of Mayfair, 56 Davies Street and 60 Brook Street will feature a mix of new and existing façades.

Sustainability targets

The development is targeting BREEAM Outstanding for offices and Design for Performance to secure a NABERS 5* accreditation. It is also targeting WiredScore Platinum certification, recognising best-in-class digitally connected buildings across the globe.
