Read the responsibility
What the reviewed pages establish.
Shell-only role stated
The barndominium page says FBi constructs the exterior shell and that interior finishes require a general contractor.
No local office published
The reviewed service-area pages give only an Indiana address for the St. Louis-area counties.
Warranty terms not published
The warranty page describes a claim-submission process but no durations or covered components.
Where the evidence stops
The reviewed pages describe a shell contract, not a completed home. Interior finishing, mechanical trades and site grading should be assumed to sit with the owner or a separate general contractor unless a written proposal says otherwise. The barndominium page quotes a finished-home cost range of $125 to $250 per square foot, which describes a whole finished home rather than FBi's own shell price. Foundation and concrete responsibility are not itemized on the reviewed pages.
Our reading of the advertised offering
When to investigate this option.
Best considered by owners who plan to hire their own general contractor, or self-manage interior work, after a post-frame shell is erected. It is a comparison point against other shell-only post-frame suppliers serving eastern Missouri and Metro East Illinois. Owners should confirm crew travel, scheduling and warranty handling from a builder without a published St. Louis-area office.
Start by confirming your exact parcel, the proposed delivery model and current availability. Ask for the contract’s included work and exclusions before treating the website description as the scope of a bid. These are editorial research questions, not a recommendation to hire this company.

Deeper source review / 2026-10-11
Thirteen responsibility checks.
Twelve are construction responsibilities; the thirteenth, geographic fit, records where the company says it works and is reported separately from the twelve.
Company statementFBi Buildings explicitly limits its barndominium role to the exterior shell, with interior finishing assigned to a general contractor and grading to the owner or a general contractor. Its service-area page names every Missouri county in the St. Louis metro and the main Metro East Illinois counties, but no local office or named St. Louis-area home project was found. The building-process page discusses permits, site timing and a project manager without assigning permit, engineering or foundation responsibility. The warranty page is a claim form without terms. Published pole barn home projects are in Indiana, Illinois, Michigan and Iowa, none in the St. Louis metro.
“Advertised” means the reviewed source names the service or responsibility. A field can name only part of a system: for example HVAC without plumbing or electrical. It does not mean the item is complete or included in every proposal. “Not established” is a research limit, not a finding that the company cannot do the work.
- Structural systemAdvertised
The company builds post-frame (pole barn) structures and describes the barndominium as a pole barn home.
- Design and engineeringVaries / options
FBi says it helps design the exterior and connects owners with architects for interior layout; engineered drawings are not described.

Mechanical, electrical and plumbing responsibility is not assigned, though interior work is directed to a general contractor.
- Interior finishesExpressly excluded
The barndominium page states that interior finishes require a general contractor or owner self-performance.

The barndominium page mentions possible septic and other trade permits without assigning utility connection work.
- Completion and handoffNot established
No completion walkthrough or handoff step was found; the process page mentions a designated project manager for start dates.
