Building a Custom Barndominium: What to Expect

Over the last few years, barndominiums have gone from a niche concept to one of the most exciting ways to build a new home—especially here in the Inland Northwest. As more Spokane-area families look for spacious, flexible, and cost-effective custom homes, barndos have become the perfect blend of modern living and rural charm.

But what does it really take to build one? At Stimson Contracting, we’ve guided dozens of clients through the custom barndominium process, from first sketches to final finishes. In this post, I’ll share exactly what to expect so you can plan your dream barndo with confidence—and avoid surprises along the way.

1. What Makes a Barndominium “Custom”?

A true custom barndo isn’t a one-size-fits-all kit. It’s designed for your lifestyle. We help clients decide:

✅ How much living space vs. shop space you need
✅ Whether you want vaulted ceilings, lofts, or open layouts
✅ What finishes, exterior siding, and roofing match your style
✅ Where to place doors, windows, and garage bays

Your vision drives the plan.

2. Finding the Right Land

Your land sets the stage for your whole project. We help you consider:

• Zoning and building codes in Spokane County

• Site access for construction

• Soil quality and drainage

• Utility availability (power, well, septic, internet)

The right property makes everything easier—and protects your investment.

3. Design and Floor Plan Planning

This is where the fun starts. We work with you to:

• Draft floor plans that fit your lifestyle

• Balance open-concept living with private spaces

• Add must-haves like attached garages, mudrooms, or covered porches

• Plan for future expansion if needed

The goal is a layout that’s beautiful, functional, and future-proof.

4. Engineering and Permitting

Custom barndos must meet the same building codes as traditional homes. We handle:

• Structural engineering

• Snow load and wind load requirements for Spokane’s climate

• Building permits and local approvals

• Any special energy code requirements

This keeps your project legal, safe, and fully up to code.

5. Site Prep and Foundation

Before the posts go in the ground, we prep the site:

• Clear trees and debris

• Level and grade the land

• Install drainage solutions

• Pour concrete pads or slabs

A solid site and strong foundation ensure your barndo stands the test of time.

6. Framing and Structure

Next comes the post-frame or steel-frame shell. This phase moves fast—many clients are amazed at how quickly the main structure goes up.

• Posts and trusses are set

• Roof and siding panels are installed

• Windows and large door openings are framed

It’s the moment when your barndo starts looking real!

7. Insulation, Windows, and Roofing

To make your barndo comfortable year-round, we focus on:

• High-performance insulation (spray foam or batt)

• Energy-efficient windows and doors

• Durable metal roofing and trim

These choices help control energy bills and keep your living space cozy through Spokane’s seasons.

8. Interior Build-Out

Inside, your custom barndominium really takes shape:

• Interior walls are framed and drywalled

• Plumbing, electrical, and HVAC go in

• Kitchens, bathrooms, and flooring are installed

• Paint, cabinetry, and trim complete the look

This stage transforms your barn shell into a true custom home.

9. Timeline and Budget Expectations

One of the biggest advantages of a barndo is that it can often be built faster than a stick-built home. But realistic expectations help:

✅ Timeline: 6–12 months is typical for a custom barndominium, depending on size, finishes, and site conditions.
✅ Budget: Generally more affordable per square foot than traditional construction—especially when you combine living space with garages or shops.

We provide detailed estimates so you know what to expect up front—no surprises.

10. Conclusion: Start to Finish, You’re in Control

A custom barndominium gives you the freedom to design your dream home without compromise—and the satisfaction of seeing it come to life exactly the way you envisioned.
