What We Do
We develop human habitats that yield perennial abundance and enduring value. We design and implement regenerative food, fuel, and shelter systems that thrive on current solar energy.
Developing this solar infrastructure requires a multi-disciplinary approach integrating ecology, agriculture, architecture, and construction. Our process and results are scalable from residential properties to neighborhoods to regions.
We work across all project phases from visioning and goals articulation to site selection, site planning, construction management, project communications, funding, and research/education.
Our clients are engaging a more resilient and enjoyable transition into the post-petroleum age.
