“Developing our creativity is how we develop our personal growth and how we can value ourselves and how others can value us”
Part of my own personal creativity is the house I am renovating/building here is Spain.
feel that the first step in sustainable building, which is what we are
trying to achieve here, is to start with a building already built,
therefore not requiring the use of yet more land to cover with concrete.
I am showing here is the steps taken so far in the Post and Beam Straw
Bale extension I am building on the north side of our house.
Landscaping the ground to make two terraced flat spaces to build on.
2 flat platforms (dug out by hand)
was done by hand using a pick ax and a spade. It is laborious work but
does not require surrounding trees and land to be destroyed to make
access for a mechanical digger.
benefit of working by hand is that clay rich soil, rubble, large rocks
and top soil can all be separated into their own specific piles, with
the exception of the top soil, everything else will be used back in the
build. A pain to do at this stage but if you are making a ‘handmade’
house it pays dividends later when building.
Digging out the strip foundations.
I decided to make strip foundations as most of the build is on solid rock.
The foundations are dug wider than the straw bales they will support.
Fill the strip foundations with rubble for good drainage, and support for the stem wall.
Pour some concrete into the strips and lay a stem wall. For the stem wall you can see we
have used two rows of concrete blocks .
After the blocks were laid, concrete pads were put in for the posts to stand on.
this photo you can see the different floor heights of the rooms with
the simple posts and beams in place. The bags of gravel were put in
before any block work was done to save me having to wheelbarrow tons of
gravel in to use as a base for the flooring.

The roofs, tongue and groove, insulated and covered with EPDM roofing.
They have not been edge trimmed yet to offer greater rain protection while building the Straw Bale walls.
The plan is to eventually create green living roofs on top of the EPDM.
you can see one of the boxes made to hold the window in place, at the
moment there is no supporting beams for the bales that will go above the
The blocks have a waterproof membrane on and the ties to hold down the first row of bales have been put in.
This is as far as I have got so far, the ties are my own idea and we will have to see how well they work.
