Featured Project: 25' x 22' Elevated In-Plant Modular Office for Food Manufacturing Plant

A Pennsylvania food manufacturing facility needed 550 sq ft of new office and conference space but couldn’t sacrifice a single inch of production or storage floor area. Panel Built delivered a fully elevated modular office system on a structural steel mezzanine, featuring two private offices, a conference room, four observation windows for floor oversight, IBC-compliant stairs, and a safety-yellow emergency egress ladder—all installed with zero disruption to ongoing operations. This vertical expansion instantly created a quiet, climate-controlled command center while keeping every square foot of the plant floor 100% productive.

Featured Project: 41' x 47' Elevated Modular Office & Gym Enclosure for Honda of South Carolina

Honda of South Carolina needed to transform a noisy, open mezzanine above their recycling area into a quiet, climate-controlled employee gym and office space—without disrupting a single shift in their 650,000 sq ft ATV manufacturing plant. Panel Built delivered a massive 41’ x 47’ x 12’ in-plant modular office system—1,900 sq ft total—installed directly on the existing mezzanine with dual HVAC zones, 3” vinyl-gypsum walls, a 20 PSF load-bearing roof, and binder-post construction for zero downtime. The turnkey solution gave 900+ associates a cool, private workout oasis and proved modular offices can conquer elevated, high-traffic industrial spaces with surgical speed and precision.
