reciprocal roof detail
the roundhouse before the walls went up
straw retaining walls pinned with chestnut stakes
protecting the straw from moisture and the liner from damage
backfilled with soil
A couple of weeks ago, after getting the garden up to speed I became involved in the roundhouse project. The round ‘henge’ complete with reciprocal roof were already in place. We have since worked on the back, straw wall, its protection from the earth backfill. We used a wooden trellis behind the bales to allow the wall to breathe, followed by an old padded pool layer to provide cushioning and then a double layer of heavy duty polyethene which drops way below ground level and is held in place with a land drain. All of which is then protected with a layer of woven landscape fabric. Where there are protruberances, they are further cushioned with squares of pool cover, not exactly ecological, but great use of something that would otherwise contribute to landfill.
Backfilling and compressing of the earth was hot, time consuming work and me being the thinnest spent most of the day squeezed between the back wall and the earth tucking in the layers of protection and then guiding and compressing the earth into place. Happy days.
