We build fully framed garages and sheds — not just prefab kits. Whether you need a workshop, a place to park, or secure storage, we design and build the right structure for your property. Each build is code-compliant, weather-resistant, and customized for function, style, and long-term use.
From basic tool sheds to insulated garages with windows, we build structures that match how you live and work. Need electric, insulation, or loft storage? We’ll plan for it. Want siding that matches your home? Done. Your structure will look great, perform well, and hold up over time.
Framed sheds and garages with real roof systems
Options for insulation, lighting, and interior finishes
Built to Washington code with proper footings

Our sheds and garages start with proper footings and framed floors (or slabs) that last. We frame full walls with house-quality materials, add roof ventilation, and install real doors, windows, and trim. You’ll get clean lines, solid framing, and enough headroom to store, work, or park comfortably.

We don’t sell one-size-fits-all kits. Instead, we measure your space, listen to your goals, and create a plan that fits the layout and local setbacks. Whether you need a simple 10x12 shed or a fully wired two-car garage, we’ll build it right — and handle every detail.
No more cramped prefab sheds or leaky roofs. Our custom buildings store lawn gear, motorcycles, power tools, or your winter tires — whatever you need protected. We’ll make sure doors fit right, shelves are easy to install, and the space works from day one.

Framed Like a House: We build using pressure-treated sill plates, full studs, and roof trusses.
Designed for Wet Seasons: Roof slopes, overhangs, vents, and sealed walls resist rain and moisture.
Ready for Electric and Lights: We frame and prep for outlets, lighting, heaters, or even panel installs.
Clean Exterior Finish: Match your house’s siding, shingles, and trim — or go with a new look.
No Kits, No Shortcuts: Every building is framed, leveled, and built by professionals — on-site.
