Designed by Guy Hollaway Architects, the 360m² Deer House was built in ancient parkland in the High Weald Area of Outstanding Natural Beauty and partially within a Conservation Zone.

 Due to the exceptional design of the house, the owners were granted permission to build the property in the countryside near Tenterden in Kent. Permission was granted using Paragraph 79 of the National Planning Policy, which supports permitting exceptional designed pieces of architecture in the countryside that would not usually be accepted.

isoenergy was asked to design and install a heating solution that was sympathetic to the natural surroundings and was consistent with the eco-built house. The house was well insulated with open plan living and glass front with views of the ancient parkland. The isoenergy solution consisted of a 14kW ground source heat pump and 800 meters of horizontal piping hidden from view. A 500litre water tank and 200litre buffer were also housed in the plant room.

The concept and design for the house evolved from the discovery of a nearby deer leap – a sunken fence built into the wall of a forest park which prevented the animals from escaping during hunts in the Tudor period.
