Things have progressed a little in the last while. Cavity size has been increased from 150mm to 200mm. We now have concrete poured and a couple of courses of blocks laid. Just waiting for some Quinn-lite blocks to arrive before we can go any further (tomorrow, fingers crossed!). We're putting in one entire course of these as a kind of ring of insulation, hopefully to reduce heat being lost from the walls down into the foundations. Block on edge will go on top of the Quinn-lites, and the floor will be poured inside this.

We've acquired a 20ft container so that gives a little extra security.
Got our wall tie's, going with Qwik-fix glass fibre ones, http://www.qwikfixings.com/glass-fibre-wall-ties.aspx. Trying to cut cold bridging wherever possible.
The well has been bored too. All 240ft of it. Great lads doing it, http://www.crosswaterdrilling.ie/
Done in one day, and a tidy crew.

We also piped off the southern and eastern sides of the site which had big gulleys running the length of them. We used 9" Corripipe and covered with stone. We'll cover with earth eventually, and you'll never know there was gulley's there in the first place!
