Montana’s Premier Post Frame Construction Company

KB Building & Supply has been the trusted choice for post frame construction in the Gallatin Valley for over two decades. Specializing in serving the business, agricultural, and residential markets, we pride ourselves on being a locally owned and operated business. Our commitment to quality, affordability, and superior customer service sets us apart from larger national firms. At KB, we are more than just builders; we are your neighbors, deeply rooted in the community, and we take pride in delivering exceptional buildings that stand the test of time.

The KB Difference: Quality, Integrity, and Affordability

At KB, our approach to construction is unique. We employ in-house developed techniques that maximize structural integrity while offering the design flexibility you need to bring your vision to life. This allows us to deliver buildings that are typically 25-50% more cost-effective than traditional stick or steel-frame structures, without sacrificing quality. Additionally, our streamlined construction process saves significant time, so you can start using your building sooner than expected.

A Local Legacy of Excellence

Founded by Keith Bright, whose family has deep roots in the Gallatin Valley, KB Building & Supply is more than just a construction company—it is a pillar of the community. Located in the Four Corners area near Bozeman, our operation includes both prefab and retail services, in addition to on-site construction. Over the past 20 years, KB has grown to employ around 20 local residents, creating jobs and fostering strong community connections.

As a company that values its local heritage, we are proud to support the Gallatin Valley community, not just through our exceptional buildings but also through active participation in community events and charitable initiatives. When you choose KB, you’re choosing a business that invests in its people and its town.
