I am bidding on a 20,000 sq ft house,yes 20,000 sq ft. The ho wants geothermal heatpumps with infloor heat in the whole house. I am half way through the bid and I am already over $200,000.
We did a 7,000 sq. ft. house with infloor and gas furnaces for the a/c blower and reserve. It was well over $70,000.
I don't know what the hell these people need these big friggin' houses for. Sorry, I got off the subject. The price all depends on the systems installed. By the way Baldie, we were requested to use ductboard in both of these houses for the insulation and accoustic properties.
