Oops, we did it again!

First, Sustainable joined with Collaborative Architecture - and now we have joined with Passive House 43 Architecture Ltd - another local architecture firm with deep roots in both collaboration and sustainability, with an unwavering commitment to providing Passive House projects. 

What makes a Passive House project unique? 

A Passive House project follows simple, but rigorous, building standards for optimal energy efficiency, resulting in an energy reduction of up to 90% for your heating and cooling. Passive House principles apply equally to an individual house for your family, to multi-unit housing for your community, and to a building for your organization. 

This latest union deepens Sustainable's proven abilities to deliver beautiful, comfortable, energy efficient, and carbon neutral projects.  

It also deepens Sustainable’s abilities to provide sustainability and Passive House consulting to support builders and fellow designers. 

Our approach is to optimize for the 3 imperatives of People, Planet, and Prosperity. 

Socially-equitable, carbon-conscious, and cost-effective solutions that balance human needs with environmental responsibility. 

Sustainable designs building solutions that serve the most basic of human needs: shelter – or housing. A home for your family, housing for your community, and places for organizations that share our environmental and social values.
