Getting started
How BuildingPlans.com works.
Search a curated catalog of CAD-ready building plans. Choose what fits your project. Buy as-is for immediate digital delivery, or start a structured modification request if you need changes.
The process
Four steps from search to build-ready.
Choose a plan
Review floor plans, exterior images, included sheet counts, and specifications. Each plan page shows exactly what you receive with your purchase and whether the plan supports modification requests.
Buy as-is or request modifications
Purchase the plan for immediate digital delivery, or click Modify This Plan on the plan page to open the Modifications Wizard pre-loaded with that plan's data. Describe the changes you need and submit a structured change-order request.
Checkout and delivery
Complete the WooCommerce checkout for digital plan delivery. Modification requests are reviewed separately by the BuildingPlans.com team and are not an instant automated service.
About modifications
When to use the Modifications Wizard.
The Modifications Wizard is a structured intake form — not a general plan search tool and not a real-time CAD editor. It is started from a specific plan page after you have already selected a plan you want to modify. It captures your change requirements clearly so they can be reviewed and quoted properly.
Common modification requests include room dimension changes, window and door relocation, roof pitch adjustments, foundation type changes, and garage size changes. Not all plans support modification requests. Plan pages indicate whether modifications are available.
Professional review note: Building plans sold on BuildingPlans.com are for planning and informational purposes. Final construction documents may require review by a licensed designer, structural engineer, or local building official. Permit, zoning, HOA, wind-load, and energy code requirements vary by location and are the buyer's responsibility to verify.
