Add Flexible Space That Matches Your Home

Custom Garages and Sheds Built for How You Use Them

Whether you need extra room to store equipment, house vehicles, or build your next project, Alliance Deck Builders of Oklahoma designs and constructs fully customized detached garages and sheds. These structures aren’t one-size-fits-all—they’re built for your purpose, your lot, and your home’s style. We offer a variety of sizes, rooflines, siding options, and door styles to match your home and meet city or HOA guidelines. From workshops and tool sheds to full-size garages with electrical and insulation, we build smart, strong, and secure.

What Can You Build With a Detached Structure?

From Storage to Studios—We Build It All

Detached garages and sheds are more than just extra storage. They're ideal for home gyms, hobby workshops, guest suites, lawn equipment, or vehicle parking. We help you design a structure that solves problems and fits your property—no kits, no cookie-cutter shortcuts. With upgrades like insulation, windows, electrical, and custom doors, these buildings become true extensions of your home—whether you're parking a classic car or starting a side business.

Materials That Last Through Oklahoma’s Seasons

Framing, Roofing, and Siding That’s Built to Endure

We build every garage and shed to stand up to Oklahoma’s toughest weather. From heavy rain and strong winds to blazing sun and cold snaps, our materials are chosen for long-term durability and performance. That includes treated framing, moisture barriers, fire-rated siding, and high-wind-rated shingles or metal roofing. Need something HOA-approved? Want a barn-style shed? We’ve got the materials and expertise to make it happen—without compromising looks or lifespan.

We Maximize Your Space Without Overbuilding

Not every backyard needs a huge garage or oversized shed. That’s why we measure your site, check setbacks and access, and build structures that make sense for your space. Whether you're tight on square footage or need room for future expansion, we deliver smart layouts and clean builds. We also design for utility—placing doors where you actually need them, adding vents or windows for airflow, and offering foundation options like slabs, piers, or skids based on your soil and slope.

Residential, Rental, and Rural Builds

Structures for Homes, Landowners, and Investors

From small storage sheds in city lots to large garages on rural land, we serve homeowners, landlords, and property investors alike. We’ve built workshop-ready garages, firewood sheds, tool buildings, and backyard studios across Oklahoma. We coordinate with surveyors, manage permits, and ensure code compliance on every build—no surprises, no delays. If you need an outbuilding that adds value and function, Alliance gets it built right.
