You need enclosed space you can place where the work is — secure storage on a site, a quiet container office, or a prefab kiosk that faces customers — without waiting on a conventional build.
Hinton Buildings helps you match that problem to a FlatBox flat-pack metal portable container building, then get it delivered, with optional installation available at additional cost. Browse the lineup at flatbox.hintonbuildings.com.
Key takeaways
- FlatBox units ship flat-pack and assemble into enclosed portable buildings.
- Common categories: storage, office, and kiosk-style customer-facing units.
- Nationwide drop-ship through Hinton’s FlatBox hub — not limited to NC lot delivery.
- Start with the job (secure tools, quiet desk, retail face) then pick the category.
Who wrote this guide
This guide is maintained by the Hinton Buildings team in Eastern North Carolina — an authorized Old Hickory dealer helping customers choose wooden buildings, tubular metal buildings, Carolina Play Sets, FlatBox flat-pack containers, and portable decks from lots in Princeton, Dunn, and La Grange. We position on quality and the right fit, not the cheapest quote.
Why a flat pack container beats “we will figure it out later”
Jobsites, events, remote lots, and backyard overflow all share one problem: you need walls, a door, and a lock — soon. Flat-pack container buildings are designed for that urgency without pretending to be a permanent stick-built project.
Storage, office, and kiosk — pick by job
| Category | Best when you need… | Think about |
|---|---|---|
| Storage | Secure enclosed volume for tools/materials | Access path, door width, site leveling |
| Office | Quiet, climate-ready workspace for people | Windows, power plan, desk layout |
| Kiosk | Customer-facing compact footprint | Traffic flow, openings, brand presence |
National note
FlatBox is a nationwide product path via Hinton. NC lot walkthroughs are great for wood and tubular metal; FlatBox is ordered through the FlatBox hub for drop-ship.
Start with the job, then the flat pack container.

What we are not claiming here
This article does not state office steel gauge, R-values, wind/snow ratings, warranties, certifications, lead times, or interior dimensions. If you need those for a project file, ask Hinton and we will pull the current manufacturer packet for your model.
Storage door options (manufacturer-stated)
Storage units are offered with side door or end door placement (manufacturer-stated). Pick the option that matches how you approach the pad with tools, pallets, or vehicles.
Assembly time (manufacturer estimate, not a Hinton promise)
The manufacturer estimates on-site assembly at roughly 2–5 hours, depending on model and crew. That is a manufacturer estimate — not a Hinton guarantee for every site, weather day, or crew. Installation is not included in the FlatBox price; optional installation is available at additional cost, so ask us for a quote.

What to ask before you buy
Use this checklist so the FlatBox decision stays transparent — quality and fit first, no mystery claims:
- Wind and anchoring: How will this unit be anchored for my site exposure? What does the manufacturer recommend for my pad type? (We do not invent wind ratings in this article.)
- Permits: Does my city/county treat this footprint as temporary or permanent? What packet do they want? Hinton does not claim permit exemption.
- Site prep: Is the surface level and drained for the footprint? Is delivery access clear for flat-pack panels?
- Category fit: Storage vs office vs kiosk — which job is primary (secure volume, quiet work, or customer-facing service)?
- Doors and openings: For storage, side vs end door? For kiosk, does the service-window size match how you serve customers?
- Office options: Do I need the manufacturer-listed electrical kit, AC, or diamond-plate floor for this use?
- Crew and schedule: Who is on-site for the manufacturer’s estimated assembly window, and how do weather delays get handled?
