I work with a lot of Scrape Developers in Central Denver. Their cost per SF to build a 2,000'ish SF above grade home with average+ finishes is about $130/SF. Now realize, that is THEIR cost. To build for a customer, they will add market up & fees to provide for their living of building homes.ew construction will run between $250 per square foot and $500 per square foot: That will mean between $275,000 to $550,000 not including the cost of the land. 0 votes • Thank • Flag • Link • Thu May 10, 2012.
