Changing from a 2-car to 3-car garage is a relatively easy change and very popular request (it also increases the bonus space above the garage). Many of our house plans already offer the 3-car option for an extra $150. Be sure to check the Optional Features available for purchase for each home.


Medium-sized Changes affect rooms and layouts but not footprint or actual house size.

Examples of changes:

  • Elevation changes including roof pitch and roofline changes

Major Changes affect the square feet and/or house footprint.

Some states require that a licensed engineer review and stamp the plans. If this is the case, you will need to hire a state licensed structural engineer to analyze the design and provide additional drawings and calculations required by your local building department.
