4 Corners Zero Energy Community

The Massachusetts Trust for Public Land coordinated an extensive conservation effort to preserve the farmland in a part of Princeton, Massachusetts called the Four Corners.  A beautiful expanse of farmland that will now be protected into the future.  One of the ways this was accomplished was with two 4 lot limited developments.

Transformations purchased the northern cluster.  A custom home was designed and built on Lot 1 for clients involved in the project from an early stage.  This home was intended to look like an historic home from the front with its large chimney in the center of the main roofline, the 12/12 windows, the barrel roll clapboards in the front facade and other historic details.

The rear of the home has 14.4 kW of solar panels, where it has been producing more energy than it has consumed.  Its HERS index came in at -9.  The first home was featured on "This New House" with Kevin O'Conner and has been showed numerous times.  For more detail, please see our Zero Energy Custom Home section of this website.

Two more lots are available as of this writing.  Bring your architect or use ours to create your zero energy dream home in this lovely setting.  Click here to send us email for more information.
