The Performance of Modern Construction.
The Integrity of Natural Materials.
Missouri's first prefabricated straw homes · High Performance Straw Core Wall System · Installed in days
Who we are
We started Building Integrity to prove that natural building can scale. Our prefabricated structural panels use wheat straw from Missouri farms to build wall systems for carbon-storing, exceptionally efficient, and visually striking homes. Every home we build is another case study for doing this better — supporting local farmers, sequestering carbon in the walls, and cutting energy bills for the life of the house. We build our relationships the same way we build our walls: on mutual respect, and made to last.
Our operations support local farmers and other small businesses, sequester carbon in the built environment, and provide reduced energy costs for the lifetime of every structure. We strive to build all of our relationships on foundations of mutual respect and cooperation, and leave behind a legacy of resilient, highly efficient, beautiful homes achieved with better building practices.
What We Offer
We don’t just make panels! We can also help you start or finish a design, install panels, or consult with your contractor so they can install them.
-
See our Panel Ready Plan section for simple homes designed specifically for straw panels and high performance. These semi-custom designs can jumpstart your design process.
-
Building Integrity is happy to fabricate panels for any custom home. If you already have an architect, reach out to us sooner than later - we can advise on how to make your design work better for panels!
If you don’t have an architect, Building Integrity co-owner Adrienne Stolwyk of Monarch Architecture is experienced with custom home design and panel coordination.
-
Our mid-Missouri shop fabricates straw-insulated wall panels, as well as cellulose-insulated floor and roof panels for custom, semi-custom, or pre-designed kit projects.
-
Building Integrity can install panels within a roughly five-hour driving radius of Columbia, MO. We are happy to consult with other contractors on installation techniques so they can feel confident building with our panels!
-
Building Integrity’s partnership with the Seed Collaborative allows us to fabricate any of New Frameworks’ Casitas. These designs are fully specified turnkey kits.
Why Straw?
It’s very insulative. It’s non-toxic. Our details make it very energy efficient. It’s carbon sequestering.
Straw (the dry stalk of the wheat plant) is collected via square baler from area farms. These are pressed into all wood frames to create super-insulated panels that can be easily delivered and erected on site. Panels are custom made based on the home’s design and receive rigorous inspection throughout the design and build process. Installed in conjunction with appropriate high-performance detailing, the panels provide an excellent level of insulation while avoiding the human health concerns that many modern building materials pose.
Various finishing options are available for the exterior and interior. Straw insulation is a perfect substrate for natural earthen or lime plaster finishes, and a base coat can be factory-applied before shipping. However, panels can also be finished with more conventional materials, like siding and gypsum board, by using a ventilated rainscreen on the exterior and furring chase on the interior.
The Seed Collaborative
Through our work with the Seed Collaborative, we’re helping grow a cooperative, decentralized network of regional straw panel producers focused on sustainable construction and low-carbon building materials. Together, we’re advancing a more resilient, regenerative, and climate-conscious alternative to conventional building systems.
