container office

A container office is an office made from a shipping or storage container. A builder cuts in windows and doors and adds insulation, finished walls, flooring, electrical and lighting. It sits directly on the ground and can be moved with a forklift or a truck.

Why it matters

NPSA says a mobile office container is perhaps the simplest and quickest mobile office option, since it can be placed directly on the ground. Other options, such as trailers and modular buildings, give more size choices. Container offices suit job sites, sales lots, events and small business use. A common mistake is to forget heating and cooling, which matter in a steel box. Another is to skip the permit check, since some cities treat a container office as a structure. Ask the provider for insulation, power and window details, and for what the city requires.

mobile office

A mobile office is an office space that is built and finished off site, then delivered ready to use. It can be a converted storage container, a trailer or a modular building. Standard units typically come with insulation, finished walls, flooring, electrical wiring, lighting, a personnel door and a window.

ground level office

A ground-level office is a mobile office that sits directly on the ground, usually a converted storage container, so that visitors can enter from the grade with no tall steps. It is quick to place on a job site or lot and does not need a raised foundation.

container modification

A container modification is a change made to a standard shipping container. It covers a single door cut-in up to a full fit-out. Common changes include doors, windows, vents, insulation, electrical work, HVAC, lining, partitions and plumbing. Sellers often group these changes into packages.

container insulation

Container insulation is material added to the walls, roof and floor of a shipping container to slow heat flow and reduce condensation. The choice of system affects comfort and cost. It is often paired with lining and HVAC. Types and thickness vary by seller.

container HVAC

Container HVAC is a heating, cooling and ventilation system fitted to a shipping container. It is used when people work in the box or when contents need a steadier temperature. It usually goes with insulation and electrical work. Systems and sizes vary by seller and use.

window cut-out

A window cut-out is an opening cut into a container wall for a window. The cut is framed and reinforced, and a window is fitted. Fixed, sliding and awning windows are common choices, often with security bars or shutters. It is a common add-on for offices and shops.
