Just a suggestion to avoid surprises. Use an architect. An architect will not only do the design you choose, but she will put the specific product types from window frames to doorknobs into the plan, exactly as you specify. Then you get a builder or contractor to bid on the project using the products on the plan. Sometimes we make a mistake of taking a low bid on a job...say it comes to $200.00 a square foot...then you decide you don't like the builder's choice of windows or doors or whatever and you want to upgrade. Then you start making changes and you turn your $250.00/sq ft job into a $350.00 sq/ft. It happens all the time. It happened to me. Know the products you want, specify every detail and put them in the plan for the bid. - Sat Aug 16 2008, 16:52
