Constructed through Butler’s authorized Butler Builder® Network
An accessory building may be smaller or secondary to a primary facility, but it still needs to provide dependable protection and useful space for years to come. Butler’s integrated building systems combine structural framing, roofing, wall systems, and insulation into a coordinated solution engineered around the project’s requirements.
Butler’s pre-engineered approach also allows accessory buildings to be configured for different purposes rather than forcing owners into a one-size-fits-all structure. Widths, heights, spans, finishes, and other building elements can be tailored to the intended application.
With Butler’s authorized Builder Network involved in the project, owners also benefit from regional construction expertise combined with Butler’s engineering and building-system knowledge.
Flexible Space for Multiple Uses
Accessory buildings can serve as storage facilities, workshops, equipment areas, maintenance spaces, agricultural support buildings, or additional operational space. Butler systems can be configured around the specific function of the building rather than relying on a fixed standard layout.
Durable Steel Construction
Butler steel building systems are engineered for long-term performance. The coordinated structural, roof, and wall systems provide a durable enclosure designed to protect equipment, materials, vehicles, and other stored assets.
Efficient Construction
Butler’s PEMB components are fabricated off-site with factory-precise cuts and pre-punched connections. This can simplify field assembly and help create a more predictable construction process. Butler states that PEMB construction can provide installation timelines up to 50% faster than conventional construction in applicable projects.
Low-Maintenance Performance
Metal building systems can provide a durable exterior that requires routine inspection and basic upkeep rather than extensive maintenance. Butler specifically designs its PEMB systems for lasting performance with minimal maintenance.
Ready for Future Needs
An accessory building can be designed with changing needs in mind. Butler systems can accommodate future expansion when incorporated into the original engineering and design, allowing owners to plan for additional space as requirements grow.
Can a Butler accessory building be customized for different uses?
Yes. Butler pre-engineered metal buildings can be designed around the intended use, with customizable spans, heights, finishes, roof and wall systems, and accessories. The final configuration can be developed around the building’s functional and site-specific requirements.
Designed Around Your Needs
Accessory buildings don’t all serve the same purpose, so the structure should be configured around how the space will actually be used. Butler offers flexibility in building dimensions, spans, heights, roof configurations, exterior finishes, wall systems, and accessories.
Depending on the project, options can include different Butler roof and wall systems, insulation, doors, windows, gutters, downspouts, ventilators, skylights, and other components. These elements can be coordinated as part of the overall building system rather than treated as disconnected additions.
For projects where appearance is important, Butler also provides multiple exterior wall and finish options, allowing an accessory structure to complement an existing facility or surrounding architecture.

Talk to a real person. Call our Pro Desk Expert Line or request a callback.
What makes a Butler building different from other metal buildings?
Butler has been engineering steel buildings for over 125 years, and AM Star is an authorized Butler distributor, not a reseller of generic components. Every building you get through us uses genuine Butler engineered parts, backed by Butler’s manufacturing standards.
Can I customize the size and layout of my building?
Yes. Butler buildings are engineered to your exact specifications, size, use, and site requirements, whether that’s a small workshop or a large industrial facility. Our team works with you from initial design through structural engineering to make sure it fits your project.
How much does a Butler building cost?
Pricing depends on size, building type, durability grade, and site conditions, so there’s no single number that fits every project. Request a quote and we’ll get you accurate pricing fast, tailored to your specific building.
How long does the process take, from quote to finished building?
Timelines vary by project scope and current fabrication schedules. Once you request a quote, we’ll give you a realistic timeframe based on your specific building and location.
Do you handle engineering and permitting?
Yes. Every Butler building is engineered to meet local codes and structural requirements, with stamped drawings provided for permitting, backed by Butler’s manufacturing standards.
What's the difference between a Butler building and a barndominium?
A barndominium is one type of building you can build using Butler’s steel building system, combining residential living space with a metal building structure. It uses the same engineered components and durability standards as our other building types.
What if I'm not building new, I just need parts or repairs?
We also supply genuine Butler parts and components for repairs, replacements, or expansions, no need to order a full building. Browse our parts catalog or contact us directly.
