Why choose Buffalo River?

Family-run.
Built on experience.

Our family brings more than 50 years of construction experience across generations. As a family-run company, we bring that perspective to every kit: thoughtful plans, practical material choices and a clearer path from the first idea to your building package.

Better materials, from the start

A better starting point for American homes.

We’re working toward better homes through the materials that go into them. ThermaTech brings framing and insulation together for energy-conscious wall assemblies. RezWood treatment helps protect the treated wood against mold, rot and termites.

We help you choose the right system for the plan. Proper installation, storage and moisture management still matter.

See more than a floor plan

Step inside before you build.

A plan is easier to understand when you can explore it. Walk through our available model homes, look around the rooms and porches, and get a feel for the layout before deciding where to start.

Our kit profiles bring the floor plan, images and package choices together. The reviewed proposal confirms the actual materials and scope for your project.

House kits.
Not barn kits.

Our home packages are coordinated for residential construction, with OSB sheathing and trusses specified for the house plan. Framing, windows, exterior doors, siding and roofing are brought together as a reviewed dry-in material package.

Choose how much arrives prepared—from treated lumber bunks to pre-cut components, pre-framed walls or pre-insulated ThermaTech panels. Your proposal sets out what is included.

High-efficiency wall panels.

Framing and insulation, brought together. ThermaTech insulated wall panels help reduce heat transfer and simplify onsite assembly. Your plan, wall assembly, and installation determine the final energy performance.

Treated lumber for better protection.

Protection built in before the first wall goes up. RezWood studs and framing are treated to help resist mold growth, rot, and subterranean termites. Treatment protects the wood; proper storage, installation, and moisture control still matter.

Understand the materials. Understand the research.

Why does mold matter?

Moisture deserves attention from the first framing delivery through everyday life in your home. Here’s what the evidence says—and where our material choices fit.

Indoor air and health

Damp and moldy environments can cause allergy symptoms, coughing or wheezing and can worsen asthma for some people. Reactions vary; others may have no symptoms. These are general health findings, not measured benefits of our kits.

Start with moisture control

Drainage, flashing, ventilation, appropriate indoor humidity and prompt leak repairs all play a part. Protective materials do not replace those measures, and no home can be guaranteed free of mold.

Our approach

Protection begins with the materials.

RezWood framing is treated to help resist mold growth, fungal decay and subterranean termites on the treated wood. ThermaTech insulated wall panels support energy-efficient construction. Product selection, installation and ongoing moisture management remain essential.

These material properties are not a promise of improved occupant health, disease prevention or a mold-free house.

What do the ThermaTech home evaluations show?

A February 2, 2026 EnviroPro report commissioned by ThermaTech describes evaluations of three occupied homes. Two had low indoor mold-spore measurements compared with outdoor samples; a third had low reported VOC and mold-related VOC measurements. The report identifies Hayes Microbial Consulting and Enthalpy Analytical as the testing laboratories.

These were observations of specific homes—not a randomized or controlled comparison with conventional homes. The homes, wall configurations and sampling dates differed. Weather, moisture history, maintenance, ventilation and other conditions can affect measurements. One home had previously undergone drying and remediation after rain intrusion. The VOC comparison used a laboratory sample distribution, not a matched control group.

The report does not isolate the panels’ contribution, measure occupants’ health or establish a result for every future home. A low reading at one time is not a guarantee of ongoing indoor-air conditions.
