Greenhouse Sales, Installation & Service, Across The Midwest!

At Wisconsin Greenhouse Company, we don’t just build greenhouses—we design and cultivate environments where passions thrive. As the Midwest leader in standard and custom-built glass greenhouses, garden rooms, and commercial structures, we create extraordinary, lasting spaces inspired by a love for year-round gardening and elegant living.

Whether you envision a personal backyard botanical paradise, a home-attached sunroom, or a large-scale agricultural facility, we bring your vision to life with structural integrity that lasts a lifetime.

Our foundation is built on old-fashioned tradition blended with contemporary class. We consider our greenhouse frames to be the best-engineered greenhouse in the world—masterfully built to handle heavy snow loads (32 LB+) and high wind loads (80 MPH+). This allows you to grow luscious tomatoes or escape with a book and a glass of wine, even during inclement weather.

We operate on the simple golden rules of honesty, hard work, and treating others how we want to be treated. This philosophy has earned us a flawless track record of completed projects and lifelong clients.

What started as a local passion has grown into a premier, full-service greenhouse design and installation firm trusted by growers, educators, and innovators nationwide.

To support our rapidly expanding family of growers and custom projects, we have reached several exciting milestones that elevate what we bring to your property:

Expanded Design & Installation Staffing: We have significantly increased our in-house team of trained design and installation professionals. With more dedicated experts on hand, we handle everything from custom 3D renderings to installing the final pane of glass entirely in-house, ensuring seamless execution and faster project timelines.

100+ Years of Combined Field Experience: Our team brings over a century of collective, on-the-ground industry experience to every build. We’ve mastered every climate challenge, engineered solutions for complex terrains, and perfected the art of durable greenhouse construction.

Powered by Local UW Alumni: We are proud to feature a team with University of Wisconsin graduates. Bringing top-tier academic foundations in agriculture, design, and engineering, our Badger alumni combine Midwest grit with cutting-edge industry knowledge.

While our roots and headquarters remain firmly planted in Madison, Wisconsin, our footprint has officially gone nationwide. Wisconsin Greenhouse Company is proud to be crafting unique, climate-adapted projects all across the country.

From enduring the harsh winters of Maine and the high altitudes of Colorado, to mastering the sweeping plains of Nebraska and managing the intense summer heat of Arizona & Texas, we engineer structures designed specifically for your local zip code and climate zone.

Ready to Build Your Sanctuary? From backyard luxury to national commercial lines, our expanded team is ready to design your next four-season growing space.
