About
In Québec’s often challenging climate, Rocket builds homes that are beautiful, durable, and energy-efficient.
William Murray, a PHIUS-certified builder, and Sarah Cobb, a Passive House-certified consultant, have been building together for over fifteen years.
Environmental mission and strategy (ESG)
Since building the Maison des Sources — the first PHIUS+ certified home in Québec and LEED Platinum — we've become even more committed to transforming the construction industry.
Having renovated many unhealthy homes, we deeply value the tools and knowledge now available to create buildings that support both longevity and occupant health. Our climate is harsh on building envelopes, but new technologies and best practices allow us to create homes that are not only beautiful, but also low in energy consumption.
As certified Passive House (PHIUS) builders and consultants, we’re here to help design and build your project.
