Helical has appointed McLaren Construction as main contractor for the £90m remodelling and refurbishment of the Art Deco Brettenham House in London.
The 128,716 sq ft of office space will be refurbished to achieve BREEAM Outstanding, NABERS 5*, EPC A and WELL Platinum ratings. The remodelling of the building will increase the outdoor terrace space to 6,600 sq ft.
The basement will be modernised to reduce car parking and provide cycle storage spaces and generous end-of-journey facilities, and building services and glazing will be replaced and upgraded.
Matt Redgrove, senior development executive at Helical, said: “We are very pleased to be partnering with McLaren to revitalise this Art Deco icon. Along with sensitively restoring the building, we will be bringing the specification up to modern day sustainability and amenity standards with the terracing across the building providing unrivalled views along the River Thames.”
Darren Gill, managing director for London and south at McLaren Construction, added: “This monumental building at the top of Waterloo Bridge will be a familiar landmark to so many of London’s workers and visitors and we will all enjoy seeing it restored and revitalised. It’s not so long ago that it would have seemed like a tall order to bring a 1930s building up to the standards of a brand new office, but that’s become a far more familiar and achievable task.”
The refurbishment work is due to complete in spring 2026.
