The first new public square for more than a century has been created in Chelsea. The first phase of Cadogan Estates’ £120m redevelopment of the former Duke of York barracks on the King’s Road is completed this week to a masterplan by architect Paul Davis & Partners. A clear-glazed cafe pavilion forms the centrepiece of the square. Laing O’Rourke was management contractor, with Elizabeth Banks Associates as landscape architect, Adams Kara Taylor as structural engineer, WSP Group as services engineer and Trevor Patrick Partnership as QS.
