If you do not have a floor plan and elevation we then charge $65.00 per hour to design and plan your home based on our Custom Design fees.

Custom Design:

We charge a retention fee of $2000.00 to begin any design project. You provide us a wish list with all the rooms, design elements, square footage, and number of stories, garage and home style. We in turn based on your criteria and discussions on how you live and use your home come up with a design or designs based on those requirements. We work to exclude those elements you are not happy with while enhancing those elements you do like. Once we have finalized your design any hours will be billed against your retention and the balance will then be applied towards your drafting fees. At any point that your retention drops below $500.00 you will be required to pay additional monies to achieve the $2000.00 retention prior to continuing with your project.

Frequently Asked Questions Regarding Modifications

Q. What is the procedure to get a modification started?
A. Fax in a written request of proposed changes and submit your initial consultation fee, and you will receive an estimate within 2 to 3 business days. If you agree to the estimate, you will be sent a Modification Agreement to sign and return, along with the plan package fee and half of the estimated modification fee. The fees are required before modifications can be made. The remaining balance is to be paid prior to shipping the completed plans.

Q. Can I receive a cost estimate by giving my changes over the phone?
A. To receive a cost estimate, you must submit your request in written format.

Q. Can changes be made to meet my local building codes?
A. Greatamericanhomeplans.com does not modify plans to meet local building codes, wind speed requirements above 80MPH or seismic requirements. Please visit your local builder or architect for these requests.

Q. Can the square footage of a house be reduced by 10%?
A. It is not feasible to reduce the entire house by a percentage amount. Bathrooms, closets, hallways, et cetera, will no longer work feasibly. However, square footage can be reduced through stretch changes.

Q. Can my builder make changes?
A. It is possible that your builder can make changes. A lot depends on the complexity of the changes, the number of the changes to be made and your builder's aptitude. It is to your advantage to have the changes on the drawings the way you want them done, not the way the builder wants to do them.

Q. Can I add brick?
A. Yes brick can be added, but please note that it adds square footage to the house. Brick is added to the outside of the studs, so the plan grows approximately 6" around the perimeter. This change affects the foundation plan, floor plan, wall sections, building sections, rooflines, exterior elevations and the structural plan.

Q. What are some of the most common types of modifications?
A. Adding/reducing the square footage of the house, enlarging a garage to a three-car garage, adding a walkout basement, revising the exterior appearance, changing 2x4 exterior walls to 2x6.
