The roof structure and canopy specialist has now built most of the innovative timber frame and roof.
Key features include:
- sustainable timber
- rainwater harvesting for watering plants and flushing toilets
- north-facing windows for natural light without solar gain
- manual, natural ventilation
- solar-heated hot water
- wood-fired heating
- rammed earth and straw walls
- insulation in the roof.
Pleydell Smithyman is architect.
The design incorporates a series of asymmetrically curved roofs with a series of north-facing windows.
A heat sensitive ventilation system makes the most of natural light whilst preventing the building from becoming too hot in warm weather.
The building and hot water is to be heated with a combination of ground source heat pump and Farm 2000 boiler that will burn waste cardboard and damaged pallets.
Coolings chairman Paul Cooling said: "The enthusiasm and "can do" attitude of the Fordingbridge team makes them all a real pleasure to work with and this innovative structure will help put Coolings in the public eye yet again."
The Knockholt centre is due to open before Easter 2009.
