Hi Barbara! We design and manufacture affordable, energy efficient kit
houses. All of our homes are custom designed, site-specific, and
suitable for off-grid living. We've recently come out with a net zero
energy home design that you may be especially interested in. We're
located in Massachusetts but ship our kits nationwide and can
coordinate with local builders. Our website is www.noble-home.net. Let us know if you have any questions!
