Thanks I'll do that. Perhaps a more relevant question to people on this group could be whether relating to cost, build ability, preference etc. Aside from the velox wall system would (or have) people used the velox floor/ceiling/ roof systems or found it easier using an alternative? I.e suspended timber floor or timber roof etc

Cheers, I'm actually a student doing a university project where I have to design a house for a family for that's self build able for £50000 and meets passivehaus standards (practically impossible I know ?) and test it using Energy plus softwaere but just after some very rough price estimates. It's a 2 floor flat roof 7x8m house

Hi does anyone have a rough cost of Velox wall system per m2 or where to find some useful price guides?!
