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.

We have been working with Panel Built for about 5 years now through ISDA. Time and time again, we have great experiences with the staff and products from sales to installation...The key factors that set Panel Built apart for us are their high-quality products, responsiveness, and top-tier customer service.

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.
