Well as for as framing cost psf....that is like asking how much a car costs.
Houses vary in degree of framing complexity, if your house is a perfect rectangle and can be framed in a week then the $ would be low.
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.
There are so many challenges to building your own house, I dont think you realize what you are getting yourself into; if its in WaterColor and has any complexities at all, I think you're asking for trouble by doing it yourself. If you hold down a full time job and expect to do this on the side, you are in for some sleepless nights.
