Custom New Homes

An opportunity to do it right the first time

No drafts, no leaks, no high heating bills. Building an energy efficient, durable, healthy home is our top priority.


Zero Energy Homes

A Zero Energy Home (ZEH) is a green home built to be airtight, highly insulated, and utilize highly efficient appliances, heating and lighting, so their energy use is minimal. Once all aspects of the home are made as energy efficient as possible, they utilize solar photovoltaic (PV) collectors to produce sufficient electricity to meet the minimal remaining energy needs of the home.

Deep Energy Retrofits

A Deep Energy Retrofit is a whole-building analysis and construction process that uses integrative design to achieve much larger energy savings than conventional energy retrofits.

Both of these project types requires a deep interest in having the most energy efficient home possible. But they don’t have to cost that much more than traditional building.  There are many rebates and incentives available to keep the costs between 5 – 10 % more than a house built to code. Of course there is also the benefit of having a home that uses a fraction of the energy that a typical house uses and the obvious cost savings associated with your lower utility bills.
