Barndominium vs. Modular Home
How a custom post-frame barndominium compares to a factory-built modular home.
Quick verdict
A barndominium is a site-built post-frame home with a fully custom, open floor plan and the option to combine living space with a shop or garage under one roof. A modular home is built in factory sections and assembled on site, which can be faster and more predictable but offers less structural flexibility. Choose a barndominium for customization and shop-plus-home flexibility; choose modular for a faster, more standardized turnkey home.
Side-by-Side Comparison
| Factor | Barndominium (Post-Frame) | Modular Home |
|---|---|---|
| Construction | Site-built post-frame | Factory-built sections, site-assembled |
| Customization | High — fully custom floor plan | Moderate — selected from plan sets and options |
| Shop / garage integration | Yes — finished living and shop under one roof | Limited; usually a separate structure |
| Build timeline | Predictable; interior finishing drives the schedule | Often a faster shell once modules arrive |
| Clear-span interior | Yes — wide open floor plans | Constrained by module dimensions |
| Site flexibility | Strong on rural and sloped sites | Needs crane access and a transport route |
| Best for | Custom home plus shop on rural acreage | Standardized turnkey home, speed |
When to Choose Each
Choose a barndominium when you want a fully custom home, an open floor plan, and the ability to combine living space with a shop, garage, or equipment storage under one roof. It is an excellent fit for rural acreage and for owners who want to put their budget exactly where they want it.
Choose a modular home when speed and a standardized, turnkey result matter most and your site has good crane access and a clear transport route. Sherman Buildings builds custom post-frame homes and offers modular options — so we can help you compare both honestly for your property.
Barndominium vs. Modular Home FAQ
What is the difference between a barndominium and a modular home?
A barndominium is a site-built post-frame home — framed with engineered columns and clear-span trusses — that can combine finished living space with a shop or garage under one roof. A modular home is built in sections at a factory and assembled on your site. The biggest practical differences are customization and shop integration: a barndominium is built to your exact plan on site, while a modular home is selected from factory plan sets.
Is a barndominium cheaper than a modular home?
It depends heavily on size, finish level, and how much of the building is shop versus living space, so there is no single answer. Post-frame construction is material- and labor-efficient, and a barndominium lets you put your budget exactly where you want it. We will give you a realistic comparison for your specific project during a design consultation.
Can a barndominium include a shop or garage?
Yes — that is one of its biggest advantages. Because post-frame framing creates wide, column-free interiors, a barndominium can combine a heated shop, a large garage, or equipment storage with finished living space under a single unified roofline. Modular homes generally cannot integrate a large shop the same way.
Can both a barndominium and a modular home be financed?
Yes, when built on a permanent foundation and permitted as a single-family residence. Sherman partners with Acorn Finance and HFS Financial, both of which have lending products suited to post-frame homes. Lender requirements differ slightly from a standard conventional mortgage, and our team will walk you through them.
Which is more customizable?
A barndominium. Every Sherman barndominium starts with a custom floor plan built in our 3D designer, and the post-frame method removes interior load-bearing walls so you can place rooms wherever you want. Modular homes offer options within fixed plan sets, which is more standardized but less flexible.
