Every shed or garage we build starts with a clear purpose. Need a place to park? A dedicated workshop? A secure place for your tools and equipment? We design structures to match your needs and make sure they’re framed, anchored, and weather-protected properly. That means building to code, managing permits, and ensuring the final product feels like a permanent, integrated part of your property.
Framed to Last. Designed for Use.
What’s Included in Our Garage & Shed Builds
Unlike prefab kits, we build from the ground up — with poured concrete footings or slabs, real framing, and proper roof systems. We offer custom door sizes, windows, siding to match your home, and full electrical or lighting packages. Whether you’re storing garden tools, running a small business, or parking your truck, we’ll build a structure that performs and adds value.
Fully Framed Walls, Roofs & Doors
Options for Windows, Power & Storage
Site-Built, Not Drop-Shipped Kits

We don’t sell cookie-cutter storage boxes. We design each build based on how you’ll actually use it. That might mean a single-car garage with power, a workshop with windows, or a basic shed to store tools and keep clutter out of the house. You tell us what matters — we handle the design, permits, materials, and build. It’s your space, done your way.

Built for Oregon’s Weather — and Your Needs
From the ground up, our sheds and garages are designed to resist Oregon’s damp climate. We use pressure-treated framing, moisture barriers, roof vents, and drainage planning to prevent leaks, rot, or mold. Siding and roofing options range from traditional shingles to metal panels, and all structures are built for long-term use, even during harsh winters or wet springs.
Unlike prefab sheds, our builds are permanent additions that require proper planning and construction. We pour real footings or slabs, build full-frame walls, and install doors, windows, and roofing that match your home. These are true structures — built to last, not just sit in the yard. Whether you need a permitted garage or just want long-term durability, we deliver the real thing.

Don't worry, we can help!
From lawnmowers to motorcycles to full workshop setups, a well-built shed or detached garage gives you freedom and flexibility. We build structures that look good, perform well, and increase your property’s functionality. Whether you want it simple or feature-packed, we make it happen with no cutting corners.
Backyard Storage Without Clutter
Fully Framed & Anchored Construction
Designed for Vehicles, Tools, or Work
Too many sheds and detached garages are built like afterthoughts — flimsy kits, poor weatherproofing, or awkward sizing. We do things differently. Every structure we build is designed to handle real use: heavy storage, workshop power tools, winter weather, or everyday parking. We’ll help you plan the right footprint, elevation, access, and details so you get a truly usable space, not just a box that fills a gap.
