New Hive was built in 2011 on the site and footprint of a Dorset Long house. Constructed on two concrete platforms resting on piles sunk into the soft Greensand. The walls are made from Ziegel blocks. These are honeycombed terracotta blocks, some of which are filled with pumice for extra insulation (the same material was used in Stoneyside, down the road – thereby hangs a story). A lime render covers the blocks inside the and out, with no paint used.
The roof has a large overhang to prevent overheating in the summer, allowing winter sun to passively heat the slate floor.
The house is mainly heated by geothermal energy from two boreholes. Cold fluid is pumped down 70m, and the return pipe heats two large heat store cylinders. One, at 33°C, heats water for the underfloor heating, with separately switched pumps to heat different zones of the houses The other is used for hot water. Hot water is also provided by solar thermal vacuum tubes. 20 solar PV panels produce up to 4kW of electricity.
The garden has its own spring, and water is pumped to a pre-existing tank above the house and then to toilets, washing machine and dishwasher. The house also has a centralised vacuum cleaning system with six outlets around the house.
