Concept Plan

Who should consider buying a Concept Plan*?

Customers who must have home plans drawn locally to meet the specific building code requirements of their jurisdiction, including local engineering or architectural seals, but who do not require plan specific documentation or drawings.
No construction prints are included with a “Concept Plan.”
The “Concept Plan” grants you the right to change this home design to meet your specific needs and the right to construct the home. You or your local architect/drafting service draft the plan to meet your specific needs in relation to building codes in your area.
This is a legal document; please keep it in a safe place. You will need to reference the License Number when inquiring about your design.
*Click here for information on Construction License options.

Dimensional CAD Plan Construction License

Who should consider buying a Dimensional CAD Plan Construction License?
Customers who must have the home plans drawn locally to meet the specific building code requirements of their jurisdiction, including local engineering or architectural seals. The Dimensional Plan is a dimensioned starting point for your architect or drafting staff/service.
A Dimensional Plan includes:
Design Basics’ federal copyright and Construction License*
Scale front, side, and rear elevations
Fully dimensioned ¼” scale floor plans
Fully dimensioned ¼” scale foundation plan
Roof plan (aerial pitches of the roof)
NO structural information is included.
*Click here for information on Construction License options.

Full Construction Drawings – PDF or CAD

  • All construction prints include the following:
    • Detailed, scaled floor plan(s)
    • Detailed, scaled elevations
    • Detailed, scaled foundation plan
  • Construction prints may include the following:
    • Detail cross sections
    • Floor structural supports
    • Roof plans and suggested electrical plans – contact us for specific details: 1.800.947.7526
  • Format Options:
    • Electronic prints: PDF email or CAD files via email
    • Many plans are available as a ‘right-reading’ reverse
    • Many plans are available as a No-Step Entry floor plan

Study Sets – PDF

  • Sometimes you need to price out a home in order to get the sale, but you need the plan to get accurate bids. Our Study Set is one complete set of construction drawings, which is the exact same set we would send you if purchasing the design.
  • A Study Set is for study purposes only and is stamped, “Illegal to Build From – For Study Purposes Only.” It does not include our Construction License, and you cannot legally build a home from the Study Set. The Study Set purchase price is 100% applicable towards the purchase of the construction print(s) for that design.
