House Plan Modifications - Basics:

House Plan Modifications:

Most designers offer modification services for their plans.  To verify if this is the case for a particular plan, check that the "Modifications Available" field on the plan's detail page states "Yes".  If the designer does offer these services, this is usually your most-timely and cost-effective path to completing your requested modifications. 

If the designer of your house plan does NOT offer modification services, you can still have your requested changes made.  First, you would need to purchase either the "Reproducible" or "CAD File" plan package (which provides you with a Copyright Release and the legal ability to have another designer/architect alter the plans and make any necessary copies) from House Plan Central.com.  Next, find a local building designer / architect / draftsman to make the changes.  They will be familiar with the local building codes and can also modify the plans to fit your needs.

Considerations:

Before requesting a modification for your house plan, consider that many common changes can be made during construction without the need to modify the actual house plan design documents.  However, this is dependent on your local building codes and the flexibility of your local building department. You should ALWAYS consult with your home builder and local building official to determine whether the changes you want to make are feasible without having the design modified.

Commonly requested modifications include:

  • Eliminating windows, fireplaces, false dormers
  • Changing garages from a 2 to 3-car
  • Reconfiguring kitchen cabinets for appliances
  • Rearranging certain interior walls
  • Changing ceiling heights
  • Changing exterior surfaces (brick, siding, stucco)
  • Changing exterior wall framing (2x4 to 2x6)
  • Changing a foundation type
  • Relocating garage door openings / adding or eliminating bays
  • Changing garages from/to rear, front, or side-load
  • Kitchen or bath layout change
  • Changing an exterior elevation style. (Using the floor plan of one home and the exterior of another)
  • Adding or eliminating a room. (This would involve changes to all aspects of a plan - elevations, floor plans, roof, and foundation details)
  • Stretching house plans in either width or depth
  • Adding a bonus room over the garage
  • Reducing or increasing the square footage of the home

    How to Get Started:

    To request a modification quote, you should begin the process by sending an email to questions@houseplancentral.com with the following information:

    Plan ID:

    Your Name:

    Your Phone Number:

    Your Email Address:

    Detailed Description of the Proposed Modifications:

    Turn Around Time, Payment of Work:

    Modification requests are, generally, forwarded to the original designer of the house plan.  In most cases, you will be contacted by the designer and they will discuss the requested changes, as well as, collect any additional information.  In about 1 to 3 business days, the designer will contact you and let you know an estimated cost to complete the requested house plan modifications as well as, an estimated timeframe for completion.  The cost and associated timeframe-to-complete is fully-dependant on the complexity of your changes, and the individual designer's pricing policies and current workload.

    At this point, you are under no obligation and can choose to either accept / not accept the designer's quote for modifications.  If you accept, you will need to follow these steps:

    - Go online to www.houseplancentral.com, and place your order for either the "Reproducible" or "CAD File" plan package.  This is required as the stock house plan (which includes your copyright release) must be purchased from House Plan Central.com. Any modification fees will be payable directly to the designer completing the house plan modifications.

    - After placing your order, send us an quick email at sales@houseplancentral.com with your House Plan Central.com Order #, and let us know that you will be having modifications completed for your house plan purchase.  We will contact the designer, and forward the order information.

    That's it!  Having house plan modifications completed is actually a very simple process and can provide a great value, especially when comparing to a corresponding fully-custom set of house plans.
