1. How much does it cost to have modifications done to home plans?
Costs to modify a home plan can vary a lot, depending on the particular plan and the kinds of changes you are looking for. Simple modifications like: Enlarging a bathroom or Removing a wall to create an open floor plan would cost a few hundred dollars, to more complex ones like: adding extra bedrooms or adding a second story to a single-story home can be thousands of dollars.

3. Are there photographs available of the home I am interested in?
Many of the homes featured have accompanying photographs. If there are no photographs posted on the plan page for a particular home, a render is available. New photos are added to the site regularly as they become available. (Note: The photographs displayed online may differ slightly from the actual plans, depending on modifications made by the owner/builder. Please refer to the floor plan for the accurate layout of the home.)
4. Can I get an address where this home plan has been built, so I can see the finished home?
In order to maintain our customers' privacy, we do not track this information. However, we have photographs for many of our home plans.
5. How is the living square footage of a home plan calculated?
We typically calculate square footage from outside the exterior frame wall, not including features like decks, porches, patios, screened porches, verandas, fireplaces, garages, basements, attics, future space, or bonus rooms. This means a livable space that is heated and finished (with drywall, paint, and carpeting, for example). If you need to clarify the square footage of a particular home plan, please contact us.
6. Will your plans be signed or stamped by an architect or engineer?
Our plans, as all architectural plans sold, will not be signed/stamped by the engineer or architect due to variations in site conditions and different local building codes and zoning regulations for each region. For your own safety, your builder or local engineer is responsible for following codes addressing: site conditions, Wind, Storm Surge, Snow Loads, Seismic and Soil Stability, etc. The builder must be responsible for this procedure.
