Problem is, with the lot costs being so expensive, its stupid to build a generic house on an expensive lot. So the architect designs a complex house and the framing contractors are few and far between that can frame a very complex house, has a good work ethic, can be trusted to buy your material, and has workers comp and gen liability insurance. If you found such a framing contractor, a price of 10 to 15 dollars psf would be a good value for you. If the framings wrong, the house is wrong. Poor material purchases by the framer could cost you a fortune and I dont think most homeowners really know what the required materials are. So its a lot about proficiency, dependability, trust, trust, trust, and insurance.
