Berkeley Estate Asset Management (BEAM) has appointed Collins Construction to carry out a £10m refurbishment and fit out to create a flagship, net zero carbon workspace in the heart of Mayfair.

Collins will deliver TWENTY Berkeley Square under its One Team Approach, undertaking a combined programme of light structural modifications and ultra-high-end fit out. On completion in Q4 2023, the 22,000 sq. ft Barr Gazetas-designed building will offer office and restaurant space of the highest quality, plus a rooftop extension serving terraces with panoramic views over the prestigious Berkeley Square.

The building’s architectural finishes are central to the project’s DNA, with Collins set to work with the design team on the restoration and repair of original features including the terrazzo staircase and the façade, as well as replacing 130 sash windows in keeping with the building’s original 1930s design.

Collins’ appointment at TWENTY Berkeley Square follows on from its successful delivery of a number of high-end schemes in Mayfair for the same client, including 14-16 and 19 Bruton Place. Through this, and during the tender process at TWENTY Berkeley Square, Collins was able to demonstrate the depth of its experience and expertise in restoring buildings to the highest standards.

Ryan Cleanthi, Divisional Director, Collins Construction, said: “Our one team approach to refurbishment and fit out ensures the level of care and attention to detail expected by BEAM and the type of occupiers on and around Berkeley Square. Collins has established an honest, collaborative, and creative relationship with BEAM over a number of successful projects, and we look forward to furthering that track record at TWENTY Berkeley Square.”

Sam Harper, Development and Investment Associate, Berkeley Estate Asset Management, said: “Each desk at TWENTY Berkeley Square will enjoy a direct view out over the best square in London. The scheme Barr Gazetas has designed, and that Collins are now delivering, will match this outlook pound-for-pound in terms of the quality of materials and craftsmanship, to create a truly special place to work."

The full design team also includes: Blackburn & Co., Gardiner & Theobald, GDM, and Webb Yates.
