Primary Product Line
Coast Studios
Four architect-designed backyard studio models — The Coast, The Saltbox, The Modern, and The Craftsman. Fully customizable, delivered and installed in 4–7 weeks, and under 200 sq ft so no permit is required in most Western Washington jurisdictions.
Built using our panelized construction system — fabricated in a climate-controlled facility, then assembled on your property in days. Every Coast Studio includes permit drawings, engineering, foundation, and a 12-month warranty.

Full Scope
General Construction Services
Beyond Coast Studios and Tiny Homes, JBS Built offers the full range of prefab construction services — residential, commercial, and everything in between.
Prefab Residential Homes
Custom houses, home additions, and specialty residential structures — designed in-house, fabricated in a climate-controlled facility, and installed on your site. From modern cottages to full custom homes.
Commercial Prefab
Prefabricated commercial structures built to spec. Mid-rise prefab, display trailers, and commercial offices — all engineered and fabricated with the same in-house quality control as our residential work.
Garages & Outbuildings
Custom prefabricated garages, garden sheds, carports, play sheds, and loafing sheds. Built to match your property's aesthetic and engineered to last in the Pacific Northwest climate.
Design & Engineering
In-house design team using 2D and 3D CAD software. We produce permit-ready drawings, engineering documents, virtual walkthroughs, and home plans — all before a single panel is cut.
Delivery & Installation
Our own fleet of delivery vehicles for local jobs. Nationwide shipping via commercial carrier for larger projects. In-house install crews and a network of approved contractors for any site condition.
The JBS Advantage
Why Prefab? Why JBS?
Prefabricated construction isn't a shortcut — it's a smarter way to build. When panels are cut and assembled in a controlled environment, every dimension is precise, every joint is dry, and every component arrives on-site ready to install.
JBS Built has been refining this process since 2002. We've built for the companies we now compete against, and we know exactly where traditional prefab falls short. Our in-house design, fabrication, and installation team eliminates the gaps.
1/3
The Time
Panelized construction installs in days, not months — because the work happens in a controlled facility before it ever reaches your property.
20+
Years Experience
Erik Johnston has been building prefab structures in the Pacific Northwest since 2002. He's built for the companies he now competes against.
100%
In-House
Design, fabrication, delivery, and installation — all under one roof. No subcontractors managing subcontractors. One team, one standard.
12-Mo
Warranty
Every structure we build is backed by a 12-month workmanship warranty. We stand behind the work because we did the work.
