At Sustainable 9 Design+Build, we specialize in designing and building modern, eco-friendly custom homes in Stillwater, Minnesota. Our mission is to create forward-thinking, sustainable homes that combine luxury, functionality, and energy efficiency—all while reflecting the unique needs of each homeowner.
Living in Stillwater means embracing a lifestyle that combines timeless elegance with modern convenience. From highly rated schools and historic architecture to a vibrant downtown filled with boutique shopping and fine dining, Stillwater is as refined as it is welcoming. With the St. Croix River, scenic bluffs, and exclusive recreational opportunities just minutes away, it’s the ideal setting for building a one-of-a-kind custom home that balances luxury and natural beauty.
Every home we build is thoughtfully designed to meet the highest standards of sustainability and craftsmanship. From geothermal heating systems to toxin-free building products, we’re committed to making homes that are as healthy as they are beautiful.
With 20 years of experience, we design and build custom homes and remodels across the Twin Cities, from St. Paul, to Edina and Minnetonka to Wayzata, Medina, Shakopee, and Prior Lake. Our team of architects and artisans creates innovative, beautifully crafted homes tailored to your lifestyle without compromising on design.
Whether you’re new to custom home building or planning a remodel, our team is here to answer your questions and guide you through every step.
Custom builds generally take around 10–14 months, depending on design complexity and permitting.
Whether you already own a lot or are still searching, we’ve got you covered. We’ll build a custom or pre-designed home on your property—or help you find the perfect spot to make it a reality.
Every build and remodel is unique. We recommend connecting with our team directly to better understand your goals and determine if we’re the right fit for your project.
Our homes are designed with sustainability in mind, often featuring triple-pane windows, energy-efficient appliances, solar-ready options, low-flow water systems, and low-VOC materials—customized to fit your lifestyle and preferences.
Every custom home we build is backed by third-party certification, ensuring we meet and verify our sustainability goals.
We don’t currently build tiny homes, though it’s a style we admire and hope to explore in the future.
