Panel Built was founded in 1995 by brothers Pat and Mike Kiernan, and began with the construction of pre-manufactured buildings. Today, Panel Built offers a complete line of custom modular offices, mezzanines, security booths, pre-assembled exterior buildings, and cleanrooms. All our multiple product lines are produced on-site, in four state-of-the-art manufacturing facilities. We offer “A Better Way to Create Space” for all of your building projects.


To Solve our Customers' Space Needs with Excellence and Great Customer Service.

Panel Built modular offices and mezzanines are relocatable, adjustable, and expandable. We offer many options to buy or lease, as well as assistance with financing.

Matchless strength and durability is the “core” of our building quality. Our light-weight, highly portable panels meet all military specifications and exceed most national building codes and OSHA requirements.

Every PBI Building and Mezzanine owner is provided an exclusive warranty of our workmanship. We stand behind our products!

Our dedicated sales team provides confidential free quotes and CAD drawings to help get your project underway. Our team is available to answer any questions about a quotation, an order, freight options, or project changes. Customer service works in unison with our shipping and installation departments to ensure on-time delivery and set up, with the least amount of disruption to your business.

Panel Built manufactures standard and custom modular buildings including One-, Two-, and Three-Story In-Plant Offices, Multi-Purpose Mezzanine Systems, Security/Guard Stations, Interior, and Exterior Equipment Enclosures, Wall Partitions, Clean Rooms, Exterior Offices, Stair Systems, and Special-Use Buildings.

For superior quality, dependable service, and innovative solutions, Panel Built is your best choice. We invite you to experience the Panel Built difference.


We needed modular facilities quickly, as our customer, Robins Air Force Base, had specific timelines we had to meet. One call to Panel Built solved my company’s need for a quality supplier and the government’s request for timeliness on this project. Panel Built performed beyond all expectations.

– DW Harper, Project Superintendent

The decision to go with Panel Built resulted in a flexible (floor plan) office addition and reduced the loss of floor space to almost nothing; while allowing an expansion that we needed.

– David Bakare CEO, Executive Coach Builders

We were very comfortable with Panel Built. There was nothing standard about this building, and we needed it quickly. They met our schedule and made sure we were satisfied.

– Stephen “Doc” Sellers

Panel Built was able to design a mezzanine structure to fit our needed dimensions. The installation crew was very professional and self-sufficient. I would highly recommend Panel Built for anyone’s office needs.

– Travis Batton, Mechanical Engineer, NEMAK
