Mitsui Fudosan Co., Ltd.

Tokyo, Japan, October 6, 2022 - Mitsui Fudosan Co., Ltd, a leading global real estate company headquartered in Tokyo, announced that through its UK subsidiary Mitsui Fudosan U.K., Ltd (CEO: Tomoo Nakamura), it will partner in the transformation of ‘South Molton Triangle’ – a large, mixed-use development in London’s Mayfair – with Grosvenor, one of the United Kingdom's leading real estate development and investment companies.

Our Group will participate – with Grosvenor – in the delivery of office and other commercial buildings in two blocks – the south and north blocks – which form the main focus of the project. Grosvenor will deliver the other phases of the project, including community, residential and additional retail elements, as well as a new 5* hotel.

Located directly opposite the western entrance of the new Bond Street Elizabeth Line station – scheduled to open October 2022– South Molton Triangle will provide a gateway into Mayfair, welcoming a broader demographic through world-leading design and a dynamic mix of occupiers.

The south and north blocks have been designed by Hopkins Architects, a major UK design firm. The wider proposals seek to preserve many of the historical features of the area, including the façades of existing buildings, while refurbishing a well-known local landmark, ‘The Running Horse’ pub in Davies Street. Additional investment will be made in creating a greener, cleaner and more pedestrian-friendly environment.

Project Highlights

  1. Participation in a significant mixed-use development project in the Mayfair area located in London’s West End
  2. First joint venture with Grosvenor, one of the United Kingdom's leading real estate development and investment companies
  3. Highly sustainable design and delivery approach, including improvements to the surrounding environment


Mayfair, where the project is located, is adjacent to Hyde Park and Green Park, two of London’s eight Royal Parks. With its attractive historical streets and accessibility by public transport, it is one of London's prime areas for retail, workspace, and hotels, including many of the highest-profile global brands.

The nearby 5 Hanover Square, an office building completed in 2012, is owned by Mitsui Fudosan.
