About Trillium Architects

Trillium Architects is a 7 person, full service, boutique architectural firm specializing in Passive House, Net-Zero and off-the-grid new homes, additions, and renovations. Based in Ridgefield, CT, we primarily work in western Connecticut and New York's Hudson Valley, but we've designed homes all over the country.

In 2015 and 2016 we won awards for Best Energy Efficient Home in the USA from both the USGBC and the DOE, we won a 3rd Place International Innovation award which we accepted at the United Nations Framework Convention on Climate Change in Morocco 2016, and we won Best Emerging Firm in CT from the AIA in 2016.

With the end goal of marrying beauty, usability, and the cutting edge of efficient design, we strive to always make the client experience of building or renovating their home top notch.

We are searching for progressive HVAC installers in Westchester County. We already have a fabulous CT based HVAC team that can work in NY but sometimes they are overloaded. We simply need a second who can work in NY. We need HVAC guys who TRULY understand energy efficient buildings. No BS! (Passive House, Net Zero Building etc. Low load buildings!) We need the REAL DEAL! We would love to know any great HVAC teams out there! Thanks for your help!

Stone veneer going up at #CoastalModern! This is the French Manor palette of Old World Thinstone from O&G. #TrilliumArchitects #energyefficient #energyefficientbuilding #greenarchitecture #sustainabledesign #greenliving #greenhome #architecture

Finally, a beautiful spring day to photograph the front of #CoastalModern! We’re very pleased with the wood cladding, and we look forward to seeing the stone veneer and stucco go up. #TrilliumArchitects #energyefficient #energyefficientbuilding #sustainabledesign #greenliving #greendesign

Did you know that cracks in framing lumber let air flow in and out of a house? All wood will naturally have some little cracks, so to completely seal a #passivehouse we have to wrap all penetrating lumber. The roof railing at #WestchesterPassiveReno will later attach to the posts shown here. #TrilliumArchitects #energyefficient #energyefficientbuilding #greenarchitecture #sustainabledesign #greenliving #greenhome #greendesign

Our Westchester project is a great example of the many layers required to build a good flat roof, and we were lucky enough to get a photo of everything going in recently. Here you can see the layers of rigid insulation (with the top one tapered), 2 layers of plywood for a sturdy walking surface, and the roll of waterproof membrane that will go over top to seal everything up. #WestchesterPassiveReno #TrilliumArchitects #passivehouse #energyefficient #energyefficientbuilding #greenarchitecture #passivehaus #sustainabledesign #greendesign

Today we’re really excited because the contractor at #WestchesterPassiveReno is prepping to do a practice run for the blower door test! This is when we find out how well the house is sealed- a critical step before starting exterior insulation and finishes. #TrilliumArchitects #passivehouse #energyefficient #greenhome #energyefficientbuilding #Passivehaus #greenarchitecture #sustainable design #greenliving #greendesign

Our #coastalmodern interior finishes have been selected! White oak floors, walnut feature wall, quartz counters and concrete tile backsplash will define the great room of this home....⠀ ⠀ #trilliumarchitects #cletile #concretetile #netzero #netzerohome #energyefficient #interiordesign
