Site description:

I spent a year searching for the right location that would offer relatively flat property and a due-south orientation to support the net-zero goals. Proximity to the Brenner Builders office in Bedford Hills was paramount. After eliminating dozens of options due to excessive shade, incorrect exposure, or roof pitch (which would have hampered the efficiency of the solar systems), I received a call from my broker about a new listing in the town of Somers – only a 16 minute drive from Bedford Hills.

The structure at 200 Tomahawk Street was built in the 1920s as a polebarn- style garage for the Somers Highway Department. It was a commercial building in a residential neighborhood, so its non-conforming-lot status came with limitations. While the footprint could not be changed, it had all the other elements required for a successful net-zero endeavor, with the added advantage of being on a well-traveled street. From a marketing point of view, the site was perfect for exposure and recognition.
