This looked like an interesting source for home plans: http://www.dreamhomesource.com/
Before you decide to actually spend money on a set of plans, retain an architect as a consultant to help you understand the plans and the impacts of your local building code restrictions in your area. You may find that you purchased a set of plans to a home you really like, but the footprint is wider than the allowable setbacks for your lot.
Beware of conflicts of interest as you proceed. Do not accept specifications from your builder on faith alone. Accept them as suggestions, but only after you verify them with your architect consultant who has nothing to gain or lose financially from the information you are paying them to give you. In addition, hire a real estate-construction attorney to help you understand the contracts and bids you get in the process of building. Again, the attorney stands to gain or lose nothing by their advice. The builder will suggest things that may or may not be in your best interests, so don't automatically assume anything he has to say to be all good or all bad. Just make sure you have an impartial consultant review everything.
Do not sign any construction contracts without a construction attorney's review. (It has to be a construction attorney. You wouldn't hire an Ear Nose and Throat specialist to perform open heart surgery, and attorneys are the same way: they specialize.)
When you choose to find a builder, try registering with ImproveNet.com. For that matter, you can also find an architect through them, both at no cost. www.improvenet.com
(By the way, I'm a General Contractor, so I'm not saying these things to speak badly of my profession, I'm only saying you should protect those hard earned dollars)
Good luck on your home, and, just for the humor of it, let us know if you end up doing any of these things:
Choose NOT to put gutters on the house. Choose to place soaker hoses in the ground near the foundation. Choose to paint any kind of brick or tile.
Sorry, long standing joke...
Post back with more questions. I'm sure regina will have something to say about this...
