Practical, Secure, and Built to Withstand the Elements
We design and construct detached garages and sheds to fit your space, purpose, and budget. Each build starts with a reinforced foundation and pressure-treated framing designed for long-term stability. You can choose from vinyl, composite, or metal siding, along with insulated walls and custom roofing. Whether you need storage for tools, vehicles, or seasonal equipment, our builds combine strength with visual appeal.
We don’t build cookie-cutter sheds. Every project is fully customized—from layout and dimensions to doors, windows, and finishes. Our garages and sheds are built to match your home’s style and stand up to years of heavy use.

Every detached garage and shed we build is designed to handle the region’s unique challenges. We install moisture barriers, structural bracing, and properly pitched roofs for snow runoff. Our crews ensure all framing, doors, and seals perform flawlessly in both sub-zero winters and humid summers. The result: a dependable, weatherproof structure that lasts for decades.

Every garage and shed we build meets or exceeds North Dakota building codes. We use heavy-duty trusses, anchored footings, and durable roofing to handle snow accumulation and wind exposure. Our wall framing and siding are sealed for moisture resistance, preventing rot or rust. From Bismarck to Grand Forks, homeowners trust us for reliable outdoor structures that perform through every season.
Your new garage or shed can be much more than a storage area. We design multipurpose spaces for workshops, hobby rooms, and backyard studios. Add insulation, electrical wiring, and interior finishes to create a comfortable, year-round environment. Whether you’re parking a classic car or storing lawn tools, our builds increase both convenience and property value.

Our garages and sheds are designed to be low-maintenance, requiring only basic seasonal checks.
