There are a few restrictions around our design due to budget, skill and lenders. Before I meet with an architect I'm trying to work out the most info I can and some trying to gain some opinions on blockwork outer skin.
The plan is for myself and my dad to lay the blocks then have someone more skilled render them
So we are looking at a 150mm timber frame stuffed with rockwool at the moment with a blockwork skin, the best block summary I've found are here: http://www.greenspec.co.uk/building-design/blocks/
Currently a product called Fibolite seems to tick a lot of boxes for being light enough to lay and ok to render on?
Are there any other options I should know about?
