Patrick Bellew part of Chelsea Barracks feature in the Sunday Times

Patrick Bellew explains that ground source heat pumps will provide 60% of the development’s heating needs. The first of eight proposed bore holes has just been drilled to a depth of 460ft. Water will be extracted at the rate of 2 gallons a second at a temperature of 13ºC and returned underground at 6ºC.

Maps from the 17th and 18th-century show the fertile soils of Chelsea used to support crops which made it the larder of London. Another distinguishing feature of the site is that there will be a vegetable patch measuring 328ft by 52ft, tended by professional gardeners. It will supply a restaurant in the main square of the luxury development and possibly a regular farmers’ market.
