Why Choose Our Barndominium Services
A barndominium offers the perfect balance between open living, functionality, and modern design, built on proven post-frame construction methods. Whether you need additional workspace, storage, or a complete home solution, we create spaces designed around the way you live.

Individualized Attention
Just as every customer is unique, so is every project. We treat each client and their project individually, always keeping their priorities in mind. For some that might include curb appeal, while others might prioritize a particular view or the design of a room. Listening is an essential part of how we work.

Ongoing Communication
No one likes to be kept in the dark when their money is on the line. We’ll keep you informed through every step of the process, answer your questions and make sure you and our team share a common understanding of the next steps for any project. Our subcontractors are part of the team — a group of trusted professionals we work with on an ongoing basis.

Accountability and Professionalism
What we start, we finish. Zepp Construction guarantees that we will stick with your project until the last detail is complete. Our attention to detail covers not only every aspect of the job site, including leaving it clean during and after construction, but also the paperwork involved on the business side.

Transparency
We won't pretend every project goes exactly to plan. What we will guarantee is honest pricing before we start, a straight explanation if anything changes along the way, and a team that treats you like a partner, not a bystander, when it does. It's not irresponsible to say we don't know something exactly yet. It's irresponsible to pretend we do.

Frequently Asked Questions
What is a barndominium?
A barndominium is a custom building that combines a barn-style structure with comfortable residential living spaces.
Are barndominiums customizable?
Yes. Floor plans, finishes, garages, workshops, and layouts can all be customized.
How long does it take to build a barndominium?
Project timelines vary depending on size, design, and features. We’ll give you a realistic schedule during your consultation.
Can I include a garage or workshop?
Yes, many barndominiums include large garages, storage areas, or workspaces.
How much does a barndominium cost?
Cost depends on size, finish level, and site conditions. We provide a detailed, written quote after understanding your goals and property, not a generic per-square-foot number that doesn’t account for your actual site.
Are barndominiums energy efficient?
With proper insulation and materials, barndominiums can provide excellent energy efficiency.
What's the difference between a barndominium and a pole barn?
A pole barn is typically built for storage, equipment, or livestock, not for living in day to day. A barndominium uses the same post-frame construction but is finished out as a livable home, with insulation, plumbing, electrical, and interior finishes built in.
Do barndominiums need different permits than a traditional home?
In some counties, yes, barndominiums can fall under different building code categories than a conventional stick-built home. We handle the permitting process as part of the build, so you don’t have to sort that out yourself.
What areas do you build in?
Grays Harbor, Thurston, Mason, Lewis, and Pacific counties, including Elma, Aberdeen, Hoquiam, Montesano, Olympia, Tumwater, Centralia, Chehalis, and every town between.
Is Zepp Construction licensed, bonded, and insured?
Yes. Zepp Construction is a licensed, bonded, and insured Washington State general contractor.
