re: Estimate on Custom Construction

Are you planning to act as your own general contractor, are you interested in getting it finished to a certain level and doing the rest yourself, or are you talking about a turnkey build? A good custom builder, on a turnkey project, will walk you through the costs on all aspects of the build. If you provide a target number of cost per square foot, the builder can help you to meet that cost, steering you toward amenities/finishes that will fall into line. You don't want to overbuild for the area, nor do you want to spec out a house that won't appraise for what you will spend to build it.

The house you linked would cost between $125/150 square foot in my area. But it could easily be more or less, depending on how much dirt work needs to be done, the size of driveway/lengths of sidewalks needed, whether the neighborhood has landscaping requirements, etc.

If you're still looking for plans, remember that corners cost money, roofline elevation changes cost money, and auxiliary spaces like porches and garages don't necessarily add $$ to the appraisal value, but they certainly add to the cost.
