A tender briefing for the £40 million redevelopment of Marble Arch House in central London has been held by British Land.
The existing site consists of two mixed use five storey buildings, 32-50 Edgware Road and 62-64 Seymour Street.
The new development, which has detailed planning consent, has been designed by Bennett’s Associates. It will feature 60,000 sq ft of prime office space and 15,000 sq ft of retail.
The development was designed to achieve a BREEAM excellent environmental rating.
Adjacent to the office building will be a development comprising 10 luxury residential apartments with a 5,000 sq ft restaurant at ground level built behind the retained Victorian facade of 62-64 Seymour Street.
Practical completion is scheduled for mid-2013.
Sir Robert McAlpine is thought to have declined to tender for the scheme.
British Land acquired the site from the Portman Estate.
The design sets out to surpass Part L carbon emission requirements by up to 40 per cent, and includes green-roofing to encourage biodiversity.
