Stem wall

This extension of the foundation is necessary to prevent the straw bales from becoming damp. Each bag is packed with a damp clay rubble mixture, tamped and layed into position then marked by a string line pulled tight and levelled.

Many hours of back breaking work!

Any of the books hubby is using for reference recommend using barbed wire between the bags to stabilise them, mainly for earthquake tremors. As this is not a large dwelling and we're not in an earthquake zone and are on a tight budget (the brief was free or recycled products), he made large foot long staples from fencing wire that was left on this property when we moved here, and drove them into the bag below as shown.

Which brings us to March 20th. A doorway has been put into place and tomorrow another farmer is delivering a couple of straw bales to try for size so it's getting exciting! Will post some more soon.

I decided to start up this blog to chronicle our attempt at eco building and hope that it may be of some help or interest to some. Although our dream was to sell the family home and self build using straw bale, the recession has dictated otherwise. The next best thing was to experiment with a studio in the back garden.

The initial brief to husband was simple. Cob walls and a living roof, however the builder has altered the plan (as he's entitled to) and aims to construct a round building with load bearing straw bale walls and a reciprocal roof with thatching. Watch this space as it continues to evolve!

The progress so far ...

Once dug down to solid ground, a layer of gravel is laid, followed by a drainage pipe which runs to a ditch and finally filled in with more gravel.

Ds3 is a super help!

The next layer consists of free clay from a farm down the road which will be placed into coal sacks. These items were obtained in exchange for Landrover repairs - just the way it should be!
