Plans to transform the former 12.8-acre Chelsea Barracks in Westminster, London, into a mixed-use development with hotel and sports facilities have been revised.

The development is being carried out by a consortium called Project Blue (Guernsey) Limited (PBGL), a joint venture between Qatari Diar Real Estate Investment Company and CPC Group, a development arm of Candy & Candy.

The Candy Brothers, directors of Candy & Candy property design and development firm, will also oversee the interior design of the buildings and act as development managers of the project.

PBGL will boast a 172,255 sq ft (16,000 sq m), 108-bedroom boutique hotel with two restaurants and a health spa, a 79,502 sq ft (7,400 sq m) sports centre with a 25m swimming pool, community hall, a public landscaped park and retail units.

The development will also have 319 luxury flats and 319 affordable housing units with exclusive health and fitness facilities, and private gardens designed by Edco London in conjunction with landscape architects the Olin Partnership.

Graham Stirk of Rogers Stirk Harbour + Partners, masterplanners for the project, said: “Together with architects Allford Hall Monaghan Morris we’ve designed a series of linear buildings and pavilions that are appropriate to their historic setting in terms of massing and height.”

Chelsea Barracks, originally owned by the Ministry of Defence, was sold to Project Blue for £959m, with a five-year payment plan, in January 2008.
