The Xyla is designed so you can “live large” in a small, extremely energy-efficient one-story space. Connectors, laundry rooms, garages, art studios, and other separate rooms can be added to expand this platform to fit your needs.Our lowest-cost platform, Xyla homes typically range from 1,100 to 1,600 square feet, and have 2-3 bedrooms and 1-2 baths. Built low to the ground, they combine natural light with deep overhangs for additional shade in the summer. When our first Xyla was built across the river in Vermont, it was tested by Efficiency Vermont and received a Home Energy Rating System (HERS) score of 44, and a 5-Star-Plus Certification for excellence in energy efficiency. That’s 86% more efficient than the average American home. In terms of air infiltration, it tested at .51 ACH50, which is almost 20% better than the stringent Passive House standard.
