The design-savvy sustainably responsible owners of this modest ‘Salt-Box’ cottage commissioned us to create an addition to their home that emphasizes the counterpoint of new vs. old juxtaposing a modern form with the existing cottage. Our solution is a functional amalgam that allows the older traditional spaces to connect with the new addition to achieve an opening in volume and light. We also utilized hydronic and passive solar energy components, and geothermal heating and cooling.
