Under construction

It doesn't look like much right now but this is expected to be one of the most energy-efficient homes in Boston when it's done this fall. The original structure is from the 1850s when it served as the workshop for a gunsmith in the Roxbury Crossing neighborhood.

Design and build firm Placetailor is in the process of rebuilding it to be so energy efficient it won't need a mechanical heating system. The original building had been abandoned since the 1980s. It is now being rebuilt with the original dimensions and with the goal of meeting the very stringent Passive House efficiency standard but without the complex upfront analysis.
