At Sustainable 9, every day is Earth Day.

We believe that true luxury is found at the intersection of high-performance engineering and biophilic design. For us, sustainability isn’t just an "add-on"–it is the foundation of every heartfelt space we craft.

Our commitment is guided by nine core sustainability principles that keep us accountable at every step of the homebuilding process.

High-Performance by Nature

Our homes are built to endure extreme Minnesota seasons while respecting the planet. By focusing on a superior building envelope, we ensure that your custom built home is as efficient as it is beautiful.

Prioritize Durability & Performance: We invest in the building shell, windows, and mechanical systems to increase comfort while lowering annual operational energy.
Superior Thermal Barriers: We utilize triple-pane windows to create an unmatched thermal shield. These high-quality units offer superior energy efficiency and sound dampening, significantly reducing drafts.
Energy Resilience: We aim to catch and store energy by promoting sustainability through geothermal, solar, batteries, and green roofs, ultimately cutting the home's carbon footprint.
Sustainable Infrastructure: We design for the long game, aiming for Net Zero performance where a home produces as much energy as it consumes.

Healthy Living & Renewable Materials

We believe a healthy planet starts with a healthy home. Our principles focus on creating spaces that nurture both the environment and the inhabitants.

Promote Healthy Living: We aim to create safe, allergy-free living spaces by using No-VOC (Volatile Organic Compound) and non-toxic materials, clean ventilation, and water filtration.
Select Renewable Materials: We work to reduce "embodied energy" by choosing natural, recycled, and carbon-negative materials.
Value Craftsmanship: We believe a home should not be a disposable product; we build beautiful artisan homes intended to be cherished for generations.

Circular Craftsmanship: Repurposing with Purpose

A key pillar of our Earth-first approach is the commitment to a circular economy, specifically our principle to minimize waste.

Better Futures Minnesota Partnership: We are proud to partner with Better Futures Minnesota, a social enterprise that transforms demolition into opportunity. Through their responsible deconstruction services, buildings are systematically dismantled to salvage reusable materials rather than being sent to a landfill.
Dem-Con Companies Partnership: For the materials that cannot be salvaged for direct reuse, we partner with Dem-Con. As a leader in sustainable waste solutions, Dem-Con allows us to divert construction debris from landfills through their advanced recycling and processing facilities.

We strive to reduce, reuse, and recycle as much as possible, whether by salvaging material or selecting new materials with high recycled content.

Materials with a Story: A Vendor Spotlight

We don't just build houses; we curate a network of elite vendors and artisans who share our relentless commitment to low-impact, high-quality craftsmanship. This intentionality begins with the blueprint, where our architectural partners design site-specific layouts meticulously engineered to maximize natural light and harness passive solar gain.

We prioritize renewable, non-toxic materials that age with grace and leave a minimal carbon footprint, ensuring that your home’s exterior and interior finishes naturally become more beautiful with every passing year. By collaborating with specialized vendors who share our vision, we strike a perfect balance between modern luxury and environmental responsibility.

Our dedication to a circular economy is further strengthened through strategic partnerships that minimize waste. We work with Better Futures Minnesota to responsibly deconstruct and salvage reusable materials, while partnering with Dem-Con to ensure that any remaining construction debris is diverted from landfills and processed through advanced recycling facilities. Together, these collaborations ensure your sanctuary is as healthy for you as it is for the planet.

Verified Excellence: Our Third-Party Standards

Sustainability is the ultimate form of luxury, but it must also be measurable. To ensure we are achieving our goals, every home we build undergoes rigorous third-party certification.

MN Green Path: All our homes include this certification, typically at the Advanced or Master level, verifying performance testing and energy efficiency.
ENERGY STAR®: We meet federal standards requiring at least 15% less energy consumption than standard building codes.
EPA Indoor airPLUS: This ensures your home utilizes construction practices that minimize exposure to airborne pollutants and contaminants.

A Future-Ready Legacy

We aim to future-proof our homes by being thoughtful toward the climate, technology, and intergenerational living. Sustainability is the peace of mind that comes from knowing your home is built for the next century-designed to be resilient, restorative, and remarkably efficient.

This Earth Day, we invite you to imagine a home that doesn't just reduce its footprint but actively enriches your life and the planet. Ready to start your sustainable journey? Contact the Sustainable 9 Team today.
