About Us

We build and maintain living infrastructure, including green roofs and walls. Our team – with expertise in architecture, construction and biology – provides turnkey solutions for living systems in built environments. Located in Chicago, we install and maintain green roofs in the Midwest. Our mission is to provide long-lasting green roofs at reasonable budgets. We have worked on green roofs for every design goal, including extensive, intensive, vegetable gardens, terraces, sloped roofs, inverted roofs, and native plantings.

We can design and implement any living system on roofs and walls: from sedum groundcover to grass lawns to vegetable and flower gardens to decorative planters within entertainment space. We have designed and installed over 11 acres of green roofs.

We are authorized to install and maintain vegetated roofs for American Hydrotech, Carlisle, Cetco, Conservation Technology (Optigreen), Diadem, LiveRoof, Soprema, ZinCo and other systems.

We are the first certified contractor for Repkin Biosystems, the developer of the UrbanRoofFarm^TM. We design, install and maintain these ultra-lightweight rooftop farms from which we grow tomatoes, basil, wheat, potatoes, lettuce, beans and many more varieties of food, fuel and fiber. Weighing merely 12.5 pounds per square foot, these rooftop farms are adaptable to many existing buildings. It’s a proven technology that is revolutionizing the industry by making cost-effective vertical farming a reality.
