More Space. More Storage. More Home Value.

Detached Garages and Sheds

Framed, Roofed, and Fully Functional

Custom Builds That Do More

Than Store

We build detached garages and sheds from the ground up—starting with proper foundations and ending with fully framed, finished, and weather-sealed structures. Whether you need a storage shed, workshop, or full two-car garage, we make sure it’s built to code and built to last.

Not Just Prefab Drop-Offs

Real Structures With Real Framing and Roofing

We don’t deliver kits. We build permanent, high-function garages and sheds with footings, floor systems, and real roofing. From basic backyard storage to insulated workshops with power and lighting—we design what fits your space and needs.

  • Poured slab or framed flooring available

  • Match siding, roof, and trim to your home

  • Add electrical, windows, insulation, and more

Storage That Matches Your Property

Designed to Look Like It Belongs

A good garage or shed should look like part of your home—not an afterthought. We match your roof pitch, siding, trim, and color so it blends naturally with your property. Whether it’s a cedar shed or a two-car garage with shingles, everything is designed for visual flow.

Materials and Layouts That Last

Built for Missouri Weather and Use

We use weather-rated sheathing, composite trim, treated framing, and ice-rated roofing for long-term protection. Doors, vents, and rooflines are all placed for drainage, ventilation, and usability. These builds are made to perform through every Missouri season.

Not Just Storage—Use It How You Want

Add Space for Work or Recreation

We’ve built backyard offices, hobby shops, garden sheds, man caves, and full garages with lofts. Whether you need more storage or a usable workspace, we’ll frame and finish your structure so it’s ready for whatever you have planned.

Why Choose a Custom

Garage or Shed?

  • Sized for Real Use: We build to fit your truck, tools, mower, workshop, or storage needs.

  • Fully Code-Compliant: Every build is permitted, engineered, and inspected to meet Missouri codes.

  • Matches Your Property: We align siding, trim, and roofing so it blends with your house.

  • Options for Power and Comfort: Add lighting, outlets, insulation, and even HVAC-ready framing.

  • Stronger Than Prefab Kits: Our sheds and garages are stick-built for strength—not dropped off on a trailer.

Don't worry, we can help!

Every Feature Is Optional—And Fully Custom

We don’t push one-size-fits-all kits. You choose the size, layout, roof pitch, windows, siding, and doors. Want to use it as a studio or heated shop? We’ll build it so it’s easy to finish or convert down the road.

  • Add porch covers, overhangs, or barn doors

  • Match your home’s siding or go with cedar or metal

  • Prep for electrical or HVAC installs during framing

More Than Just Storage

Detached Builds That Add Real Property Value

A well-built garage or shed adds more than function—it adds equity. These aren't backyard boxes; they’re permanent structures built with the same quality as a home addition. They raise value, increase curb appeal, and improve daily life.

Sizing, Codes, and Build Options

Questions About Detached Sheds and Garages

Detached builds come with different regulations and more options. Whether you're looking for simple storage or a fully powered workspace, these FAQs cover what most Missouri homeowners want to know.

Do I need a permit for a detached garage or shed?

Yes. We handle all permits, drawings, and code compliance for every structure we build.

Can you match the shed or garage to my house?

Absolutely. We match pitch, roofing, siding, and even trim details to your home.

What’s the best foundation type?

Most garages use a poured slab. Sheds can use concrete or framed floors depending on size and use.

Can I add power or future insulation?

Yes. We can pre-frame and wire for lighting, outlets, and HVAC—ready to finish now or later.
