in general, most of the architects we spoke with quoted 150-200 per sqft, but honestly, it's impossible for them to truly gauge it. Most of it depends on the quality of home you are looking to build. Numerous factors heavily influence the cost of the home. Frame material - Steel, cement, wood external material - brick, stucco, concrete, metal, hardy plank Window sizes and thickness ceiling heights flooring - tile,wood, cement all these factors can sway your home cost from 130/sqft to 200+/sqft. The architect will almost always ask atleast 150 as he probably doesn't want to design a modern home w/o any freedom of design (he'd have to use all the cheapest materials). i'm pretty sure architect fees vary dramatically, but i'd expect 15k->40k for that fee alone.
