What does sustainability
mean to us?

We are committed to doing our part in environmental preservation by constructing high quality, energy efficient buildings. To have a minimal environmental impact, we try to limit waste, pollution and greenhouse gas emissions. We take a holistic approach to sustainability by working with a range of systems including: permaculture gardening, rain water collection and treatment, solar power and hydrogen as energy storage.

We are not alone in our goal to heal earth. Organizations like 350.org inspire us to take this small step towards solving the problems arising from the world’s growing energy demand. By extending our knowledge and expertise to others, we hope to over time form a cleaner, healthier world.
