I'll phone them Monday and find out the straight goods on prices and logistics.
If the price shocks me I will rent plywood forms and make a traditional concrete house with exterior insulation applied.
I don't see the need for interior insulation it would allow for faster heat up times but a passive house constant temperature is the goal not quick heat ups.
Today I'll price plywood form rentals and add in the concrete and insulation costs for a 1000 sq.ft house with 2.5' crawl space , then I'll be ready to compare to ICF's costs.
The prices will dictate what I do
