Mirror prints

Building the design in reverse? No problem! Mirror prints, where the plan is printed in reverse are available. For further information check the Plan Packages section by selecting the View Pricing Options button on the page for the particular plan you have chosen.

Red-lining blueprints
This is, by far, the most common way that changes are made. It is also the simplest and least expensive. Although our industry uses the word "blueprints", this is a holdover from days past. All the plans used today for construction are printed on white paper with black or blue line lettering. Because of this fact, notations are easily made on these prints. They can be made by pen, pencil or a red line pencil, which stands out clearly, — hence the term "red-lining". Red-lining is not suitable for major changes, but is suitable for the vast majority of changes, such as:

  • shifting of interior partitions that have no effect on structural spans
  • extending a wing of a house lengthwise that has no effect on structural spans
  • material changes, specifications, fixtures, cabinet layouts, contract provisions, etc.
  • shifting, adding or changing windows or doors
  • addition/deletion of fireplaces, garages, false dormers, raised/dropped ceilings, etc.
Red-lining is by far the most common way changes are made

If it involves something other than material or specification notes, red-lining is best done by an experienced contractor who is familiar with your local codes and would know if the change requires further input from a local professional. Since plans may not be photocopied, make sure to order enough sets - usually at least 8 - so each can be noted with the proposed changes. A red-line set is acceptable for contracts, most lending institutions and most building departments. If you are building in very high wind zones or flood plain zones where local engineering is required red-lining may be unacceptable.


Where major changes are contemplated, a reproducible is suggested. See the View Prices link on the page for the specific plan you are considering. The reproducible allows an experienced, local draftsperson to add, erase or draw changes to any plan. Reproducibles are also extremely helpful where local engineering or code modifications are required. Changes that may be made with our reproducibles are as follows:

• enlarging the home in any direction even where roof pitches or rafter lengths are changed
• adding a room, garage or porch
• changing foundation types, if not available with the basic plans (most are available, so check first)
• elevation changes including roof pitch and roof line changes
• significant, interior layout changes
• adapting a plan to meet local codes or to provide engineering where required

Reproducibles are best modified by a local architect, designer or engineer, but may also be modified by an experienced contractor. Authorization is provided to enable you to make prints from the reproducibles at a local copy shop. Copy shops are not permitted to reproduce house plans without specific authorization.
