Storage, Parking, or a Workspace—We Build It Your Way

Detached Garages & Sheds in Wisconsin

A Smarter Way to Add Secure Space

Custom Detached Structures for Any Property

We don’t do one-size-fits-all kits. Every garage and shed we build is planned around your yard, layout, and purpose—whether it’s a compact garden shed, a full-size two-car garage, or a heated workshop. We handle everything from pad prep and framing to roofing and finish work, using weather-rated materials that hold up in Wisconsin’s climate.

Built Strong, From the Ground Up

Framing, Roofing, and Finishes That Perform

Our structures are framed like permanent buildings—with pressure-treated base plates, snow-load-rated roofs, and weather-sealed siding and trim. We offer everything from basic utility sheds to finished-out garages with insulation, electrical, and garage doors. You choose the layout, we take care of the rest—including optional add-ons like lofts, windows, shelving, and ramps.

  • Built on slab, gravel, or pier foundations

  • Cedar, LP SmartSide, or metal siding available

  • Custom doors, windows, lofts, and electrical upgrades

Designed for Storage, Work, or Hobby Use

Make Your Garage or Shed Work for You

These aren't cookie-cutter storage boxes—we build spaces that fit your routine. Need a heated shop for woodworking? A ventilated lawn shed? A two-bay garage with storage above? We’ll tailor the size, layout, and finishes to fit your goals. Our sheds and garages are ideal for gear storage, home gyms, hobby shops, or even backyard offices—fully enclosed, secure, and built to code.

Material Choices That Last Through the Seasons

Weather-Resistant Siding, Roofing, and Framing

We use construction-grade materials suited for Wisconsin weather—cedar, LP SmartSide, metal panels, and pressure-treated lumber. Roofs are framed for snow load and finished with shingles or metal. Doors and windows are sealed, trimmed, and properly flashed. Whether you want a rustic look or clean modern lines, we build for appearance and performance, with materials that last decades.

No Kits, No Surprises

Fully Custom Designs—Installed by Pros

Everything we build is done by our team—not outsourced, not prefabbed. We take measurements, sketch your layout, and create a structure that fits perfectly in your yard and meets your goals. You get clear pricing, timely construction, and a finished product that’s strong, level, and ready to use. We also handle permitting and code requirements so you don’t have to.

Detached Garage & Shed FAQs

What Property Owners Ask Before Building

Here are answers to the most common questions clients ask when planning a detached structure with us.

Question 1: Do I need a permit for a shed or detached garage?

Most permanent structures require permits. We handle all the paperwork and ensure code compliance.

Question 2: Can you build on an existing pad?

Yes. If the pad is level and structurally sound, we can build directly on it after inspection.

Question 3: How long does it take to build a garage or shed?

Most sheds are completed in 1–3 days. Garages typically take 1–2 weeks, depending on size and finish options.

Question 4: Do you offer insulated or finished interiors?

Yes. We can add insulation, electrical, drywall, or paneling to create workspaces, hobby zones, or heated storage.
