When setting up a temporary site office, security and comfort are paramount. Our 20ft x 8ft Steel Anti-Vandal Office Cabin is designed to withstand harsh weather and high-risk site environments while providing a warm, modern, and productive workspace.
Ideal for construction sites, industrial yards, farm offices, seasonal commercial hubs, and event management bases, this 20-foot steel cabin provides 150 sq ft of secure floor space without requiring permanent foundation work.
High-Grade Steel Construction: All-welded steel frame and corrugated side panels offer high resistance against forced entry, vandalism, and extreme UK weather.

Integrated Security Shutters: Windows are protected by internal-locking steel shutters that fold flush and secure from within the cabin overnight.
Fully Insulated Envelope: High-density thermal insulation lined with wipe-clean wallboards reduces heating costs during winter operations and keeps the cabin cool during summer months.
Commercial Vinyl Flooring: Heavy-duty, seamless anti-slip vinyl floor covering designed for high foot traffic, mud, and easy daily maintenance.
Plug-and-Play Power: Equipped with a standard 32A external commando socket for fast connection to site mains or a temporary diesel generator.

In most cases, 20ft steel anti-vandal office cabins are classed as temporary structures and do not require planning permission, particularly when used on active construction sites or industrial land. However, if the cabin will remain in place long-term (typically over 28 days on non-construction land), check with your local planning authority.
The office cabin comes pre-wired with an external 32A single-phase commando socket. You can connect it directly to an onsite mains supply, distribution box, or diesel generator using a standard commando lead.
