Developer Qatari Diar has appointed a new team to draw up a masterplan for the mixed-use redevelopment of the 12.8-acre (5.2-hectare) Chelsea Barracks site in Westminster, London.

Dixon Jones, the London-based architects behind the refurbishment of the Royal Opera House, have been selected along with Squire and Partners and Kim Wilkie Associates to create a design framework for the scheme. The firms were chosen from a shortlist of 10 teams by an evaluation panel, which included representatives from property group Grosvenor, the Prince's Foundation for the Built Environment and international and local architects.

Qatari Diar's chief executive officer and managing director, Ghanim bin Saad Al-Saad, said: "Qatari Diar has a long-term commitment to major investment at this site, in order to create a magnificent and sustainable new neighbourhood, respectful to the traditions, diversity and cultures of the surrounding urban fabric, and delivering the private and public spaces where people will want to be. "The masterplan process continues the journey of investigation and consultation which has met with such a positive response over the past few months. We would like to continue the working partnership which has been evolving between ourselves and the local community, in order to deliver a very special place for London."

Earlier this year, state-owned Qatari Diar withdrew its plans to redevelop the site, which included a 108-bedroom boutique hotel with two restaurants and a health spa and a 79,502sq ft sports centre with 25m swimming pool after designs by Rogers Stirk + Partners were criticised by the Prince of Wales.
