A Sustainable,
Eco-Friendly Home

During the construction process, our prefab homes generate about 80% less waste then standard site built homes.  A controlled factory setting allows us to use construction materials in a more efficient manner.  In addition, waste and poor workmanship caused by weather is eliminated.  The National Association of Homebuilders (NAHB) states,  “There are tremendous benefits to building parts of the home in a controlled facility, materials are protected from the weather and used in a more efficient manner.”
