This dwelling in a sustainable woodland, filled and planted to restore a worked-out quarry 50 years ago. Construction is virtually all timber, has a heat pump drawing from a reflecting pond and south facing banks of earth. The whole site is worked as permaculture. There is reed-bed water treatment and a well on site. Passive solar principles were applied. Good daylight factor, especially from the high sky component, in dense woodland drove the design and deciduous shading in Summer helps avoid overheating.
