Expertise in Sustainable Building Practices

At Sustainable 9, it’s our mission to continue helping homeowners achieve sustainability long after their home is built. Our world is full of buildings that aren’t intentional about the materials or energy they use. That’s not the case with the homes designed and built by Sustainable 9. Every part of your home will be sourced in an eco-friendly manner. We have over two decades of experience with achieving the highest levels of energy efficiency possible in our homes.

While the assumption is that a sustainable home will cost more, that’s not always true. While there might be a slightly higher upfront cost to a sustainable home, you’ll achieve long term benefits in the form of lower monthly utility bills plus cleaner & healthier indoor air.

Stunning Minnesota Modern Designs

As one of Minnesota’s premier modern home builders, we’ve built a reputation for both excellence and performance. The homes that we build feature the highest quality products on the market. Our focus on the details, our commitment to craftsmanship and our attention to detail is evident for decades after the home is built.

We started our firm because we felt that Minnesota didn’t have enough modern and contemporary homes that also focused on being sustainable. Because our teams have strong backgrounds in all areas of architecture, design, and energy efficiency, we’ve been able to create fabulous award winning homes that our customers absolutely love. Our now famous “Minnesota Modern” design style has become a staple of the homes we build.

Building Homes that Last

Our process allows us to build homes that will physically last the test of time and continue to be your dream home for years to come. At Sustainable 9 we’re one of just 2 builders in Minnesota that have been building homes to the Department of Energy’s Zero Energy Ready standards and we’ve been doing it for years.

The City of St. Paul is requiring multiple green certifications for all the custom homes being designed and built within the Highland Bridge Development. Because it’s already been part of our existing process since the founding of our company, we’ll guide you through those sustainability requirements. Our expertise in these areas will ensure that these stringent certifications are achieved while keeping the impact on your budget to a minimum.

We are an Approved Builder within the Highland Bridge Development

The new Highland Bridge development in St. Paul’s Highland Park neighborhood is an exciting chance for the city and its future citizens to make a lasting impression on the neighborhood for centuries to come. Our goal is to help our clients and the city fill the neighborhood with incredibly beautiful and energy efficient homes.
