I’m assuming BRF means barndominium. In Oklahoma, a common ballpark is about $120–$200 per square foot for a typical build, with some sources also citing lower kit-only ranges around $32–$68 per square foot before full turnkey costs are added.

Quick Scoop

  • Kit or shell pricing: often around $32–$68 per square foot in Oklahoma.
  • Turnkey build pricing: often around $120–$200 per square foot depending on design, materials, and finish level.
  • Smaller DIY-heavy projects: some estimates for a 40x60 barndominium in Oklahoma run $140k–$250k.

What affects the price

The biggest drivers are:

  • Size of the building.
  • Whether you buy a kit only or go fully turnkey.
  • Interior finish level, since kitchens, bathrooms, HVAC, and flooring can change the budget a lot.
  • Labor availability and local code requirements in Oklahoma.

Practical example

A 2,000 sq ft barndominium in the turnkey range could land roughly between $240,000 and $400,000 using the $120–$200 per square foot estimate.

If you are only pricing a kit or shell, the upfront number can look much lower, but the finished total usually rises once labor and interiors are included.

In short

If you mean a barndominium, the safest working estimate for Oklahoma is $120–$200 per square foot finished , with kit-only options cheaper and fully custom projects sometimes higher.
