M-Line

These designs were created to serve as replicable models of affordable and sustainable residential design. We make the ready-to-build designs available to qualified homeowners and housing organizations. The project originated with a bequest of Madeline Blakely Heath to South Mountain with the instruction that it be used to bolster the efforts of affordable housing on Martha’s Vineyard. In honor of Madeline, we abbreviated her name, and the houses became known as M-line homes. These one, two and three-bedroom designs are all net-zero energy possible when paired with rooftop solar energy.
