Smart + Efficient

Did you know that you can live in an all-electric house that costs about $30 per month to heat, cool, and operate? Trillium’s homes – whether they are 2,000 sf or 10,000 sf – are built to meet this goal. We utilize tried and true building methods alongside the latest tech and materials to produce the most reliable, top-of-the-line, clean energy homes available.

Safe + Healthy 

There are so many toxins and allergens in our world these days. From building materials to indoor air and water quality, Trillium’s sustainable homes are designed to be healthy and free of Red List items, and consistently provide fresh clean air. Knowing that your house is healthy and clean allows you to breathe easy - as your house is the safest place you can spend your time and it will keep you and your family healthy and allergy-free all year long.

Leave No Trace

Our clients care deeply about the environment. Sustainable building materials and methods reduce the carbon footprint of our homes. We strive to further reduce this footprint with each project - whether that is by reducing the energy loads, by providing alternative fuel supplies to achieve Net Zero, by using benign or carbon negative plant based insulations, or by collecting water for irrigation, we are reaching ever more rigorously toward ensuring each house ‘leaves no trace.' Imagine if every home were a Trillium Home!

"...And yes, we're settled in. Hard to believe we live here. It's gorgeous and what a labor of love, blood, sweat, & stress (no tears) :). Thank you for all that Trillium & BPC have done."
