This conversion of a former BT Telephone Exchange building near, Annan in Scotland is currently at construction stage.

Our client’s brief was to create two, fully sustainable dwellings. In order to achieve this our design incorporated:

  • Two layers of sheep’s wool insulation lining to all existing external surfaces
  • Ground source heat pump
  • 5.5 m diameter wind turbine (connected to grid)
  • Underfloor heating
  • Heat exchange system
