Whether you're planning to build a new house or you're looking for designs to build your next investment project, we have the plans. With an extensive selection of duplex, triplex and multi-family apartment plans to choose from, as well as single-family home plans, you are sure to find a design that suits your needs and budget. Or, contact us about modifying any plan on our site. We can provide most modifications at no extra charge.

The PlanSource, Inc advantage:
Unlike other websites that are operated by the same parent company and acting as resellers for the designs of others, we are an independent company with our own exclusive designs. With everything being done in-house rather than offering 3rd party plans across different websites, it allows us to keep overhead down and work with you on achieving the plans you desire for your project at a better price. In short, we are not a "middle man" in your plan search like so many other plan sites.

To help keep your construction costs down, most of our plans are designed from the beginning to be light on material as well as providing comfortable living spaces.


And as always....free standard shipping on all orders!
