https://www.self-build.co.uk/build-cost-calculator/build-cost-calculator-house-page/ Using all the same parameters ICF comes out higher than block work. Doesn’t appear to be taking into account time saved on labour?

Thanks for the reply. I’ve been reading and the common theme was that going the ICF route would add 5-8% to the overall cost, it’s a 275 sq/m house so that would add quite a lot to the overall cost. The main thing that stands out for me is the insulation benefit and reduced build time (“Lego for adults” being a common thing I’ve been seeing) - think I’ll be committing to this route and can get cracking with the plans.

Hi, New to the forums. I’m just about to embark on the very early stages of a new build project and have this question.... If ICF takes next to no time to be installed/concrete poured/etc compared to more traditional build methods - why does it cost more? From what I’ve been reading it’s much less labour intensive and last time I checked polystyrene isn’t that expensive! How would one get the cost down so it falls inline with a traditional structure? Thanks
