What Is the 19' Office Unit?

The 19' Office Unit is Flatbox USA's largest portable steel office, with a fully enclosed, finished workspace built for teams that need real room to work without the cost or permanence of traditional construction. Our office unit measures at 19' × 7.5' featuring 50mm insulated panels, a smooth, finished interior wall surface, and two operable aluminum windows with interior locks. It's designed to provide a comfortable, functional workspace for ongoing daily use. It ships flat-pack, with a marine-grade subfloor with a black rubberized coating, a secure locking system, and forklift pockets for easy relocation as your project needs change.

Is the 19' Office Unit Right for Your Business?

The 19' Office Unit fits businesses and teams that need a private, finished workspace on-site rather than a customer-facing structure:

Security stations and command centers requiring an enclosed, lockable space
Property managers and facilities teams needing on-site administrative space
Multi-person teams that need room for several workstations at once
Businesses needing a finished, move-in-ready interior rather than a build-out shell
