Free Foundation Plan Modifications – Customize Your Build with No Extra Cost

Most house plan companies charge hundreds of dollars just to switch the foundation type. We don’t. We understand that every building site is unique, and your plans should adapt to your lot—not your budget. That’s just one reason why our house plan benefits are unmatched in the industry.

What Foundation Types Are Available?

When you choose your favorite floor plan from our extensive collection of house designs, you can select from the following options:

• Slab Foundation – Best for warm climates or level lots where ground movement is minimal.
• Crawlspace Foundation – Ideal for moderate climates and areas that require ventilation beneath the floor.
• Stem Wall Foundation – Great for sloped lots or regions needing additional elevation for flood protection and support.

Our architectural team will adjust your plan to the foundation type you choose—CAD and PDF files included—at no additional cost.

How It Works

Once you’ve selected your preferred house plan, simply specify the foundation type during checkout or email support@myhomefloorplans.com. Our design team will update your construction documents accordingly and send you a complete, build-ready package.

Structural engineering is already included with every plan, ensuring your revised foundation meets local code requirements. While our engineering documents are not state-stamped, they are formatted for easy local review and approval by a licensed engineer in your state.

Why We Include It for Free

Unlike many competitors who charge extra for even basic plan edits, we believe your foundation choice shouldn’t cost more. A free foundation plan modification might seem small—but it can save you hundreds and prevent delays during construction. All of our plans are designed by builders, for builders, with flexibility built in from the start.

Explore our other included benefits like unlimited build licenses, included CAD files, and the ability to preview every plan sheet before purchase.
