Why live in a wood house when ICF is the strongest and most sustainable building technology? This custom 6,500 sqft ranch w/heated 5 car garage is constructed of steel-reinforced 6 inch solid concrete walls welded into bedrock, erected all the way up to the roof. Homes built using Insulated Concrete Forms (ICF) provide the highest energy efficiency with R-value 50+ ideal for Colorado’s climate. ICF walls average 44% less energy to heat, 32% less energy to cool, have a 6+ hour fire rating, withstand 250 mph winds, reduce sound to 50+ STC, & the EPS insulation creates a zero-air leak barrier 100% termite/insect free & mold/mildew resistant. Built at the top of a ridge at the northern tip overlooking Dawson Butte, engineers designed a fully open concept with unobstructed views by using the ICF walls as support beams. Even the deck floats in the air through suspended steel welded into the core concrete structure.
