20ft x 12ft Modular Home & Office Container – Anti-Corrosive Steel, Open Plan (New)

Description

The 20ft x 12ft Modular Home & Office from Big Bear Containers is a heavy-duty, wind- and watertight steel unit engineered for secure, long-lasting performance.

This 20ft × 12ft modular home and office container is a new, purpose-built modular structure on a reinforced steel frame with a protective anti-corrosive exterior coating — the widest single-unit modular building in our range at 12ft (3.66m) external width. The additional width over our 20ft × 10ft Insulated Container Unit provides a noticeably more spacious internal footprint, making this unit better suited to layouts requiring a defined office workspace alongside a separate living or meeting area within the same open-plan floor area, rather than a single-function room.

The unit is delivered as a weatherproof open-plan shell — structurally complete, insulated, and ready for fit-out. Unlike the 10ft-wide unit which includes pre-wired electrical and pre-plumbed water as standard, this 12ft-wide unit provides those systems on request — electrical installation, lighting, power outlets, and HVAC can be specified and priced before order for a turnkey build, or the unit can be delivered as a dry shell and connected on site by the buyer’s contractors. Confirm your required fit-out level with Big Bear Containers at time of order to receive an accurate quotation.

The reinforced steel frame provides long-term structural integrity in outdoor environments. The anti-corrosive exterior coating protects against weathering, UV degradation, and moisture ingress without the maintenance requirements of painted steel. The unit is portable by crane or forklift — with the 12ft width exceeding standard road transport lane widths in many states, confirm delivery logistics and site access requirements with Big Bear Containers before ordering. Internal dimensions are not confirmed — finished internal clearances will be reduced from the external 20ft × 12ft footprint by wall insulation and lining thickness. For guidance on modular building siting and permit requirements in the USA, refer to the US Department of Housing and Urban Development manufactured housing guidance and confirm requirements with your local authority before siting.

Ideal Uses

Construction & Durability

Structurally the 20ft office unit is factory-fresh one-trip steel with a rigid box frame: two rails, two headers, four posts, eight castings. Load paths run through the corners, so the walls stay unstressed and the doors keep their seal for the life of the unit.

Delivery & Site Preparation

Delivery is by tilt-bed truck: the bed angles up and the 20ft office unit slides off onto your ground — no crane, no second lift. Allow about 75ft of clear, straight approach so the bed can tilt and slide the unit off. Firm, level ground matters more than anything else; gravel or concrete piers under the four corners will keep the doors swinging true.
