Custom Post-Frame Buildings in Montana
Family-owned and operated since 2005, H&H Custom Buildings specializes in turnkey post-frame buildings, barndominiums, and agricultural structures. Built by a Montana family with over two decades of experience in the Helena Valley.
Post-Frame Buildings Built for Montana Property Owners
H&H Custom Buildings has been constructing post-frame buildings across the Helena Valley and surrounding Montana communities since 2005. Founded by father and son Al and Lucas Irvin, the company combines decades of building and sales experience to deliver reliable structures for property owners in East Helena, and nearby areas. Their projects include personal shops, agricultural buildings, and custom barndominiums, all built through a turnkey process that covers excavation, concrete, framing, roofing, insulation, and interior finishes.
Post-frame construction is one of the most efficient building methods for large-span structures in Montana. By using embedded structural columns instead of traditional framing, these buildings allow wider open interiors, faster construction timelines, and strong long-term durability. H&H has the capacity to deliver 50 or more post-frame buildings per year, with a dedicated crew focused on starting and finishing every project without delays.
Reviews & Testimonials
H&H is the only Contractor/Builder you will ever need. They are very skilled, fast, and do the job right the first time. They show up on time and are a pleasure to work with. The process from design, customer service, to the build is exceptional. They pay attention to every detail, like lining up screws, using good materials, etc... I highly recommend. I will only use this company in the future. Thank you H&H for making my two dream patios beautiful.
Owners are fabulous and very easy to work with. Answered all my wifes and my questions at this time.
Great family owned and operated company. Smaller crews but they really work hard. They do quality work and in a timely manner.
Frequently Asked Questions
What types of buildings does H&H Custom Buildings construct?
H&H Custom Buildings specializes in post-frame construction, including personal and commercial shops, agricultural equipment storage, multi-use buildings, equestrian facilities, and barndominiums with custom living spaces. All projects are delivered turnkey from site prep through finished interior.
Where does H&H Custom Buildings serve in Montana?
H&H is based in East Helena, Montana, and serves property owners across the Helena Valley and surrounding communities within approximately 90 minutes of Helena, including Townsend, Boulder, Anaconda, and Whitehall.
How long does a post-frame building project take?
Most post-frame buildings are completed in two to three weeks of active construction. Total timeline from contract signing to build start depends on scheduling, but H&H provides a clear schedule date at signing and rarely move crews off-site once a project has begun.
How much does a post-frame building cost in Montana?
Post-frame building costs in Montana vary based on size, foundation type, and interior finishes. Most H&H projects range from $50,000 to well over $100,000 for larger or fully finished structures. H&H provides detailed estimates based on your specific dimensions, site conditions, and finish level.
What is the difference between a barndominium and a post-frame building?
A post-frame building is a structural construction method using embedded vertical columns as the primary load-bearing system. A barndominium is a specific use case — a post-frame or hybrid structure that includes living quarters alongside utility or shop space. H&H builds both.
Does H&H handle the full project or just the shell?
H&H Custom Buildings handles turnkey delivery, including excavation coordination, concrete, structural framing, roofing, insulation, electrical, plumbing, and finished interiors. Clients can choose the level of finish that fits their project and budget.
