20ft Custom Container Office & Tiny Home — Triple-Glazed, Full Utilities, Eco Build (New)

Description

The 20ft Custom Container Office & Tiny Home from Atlas Container Supply is a premium, wind- and watertight steel unit engineered for secure, long-lasting performance.

This 20ft custom container office and tiny home is a new, fully equipped modular unit providing 14 sqm (approximately 150 sq ft) of internal floor space in a compact 6m × 2.4m footprint. Unlike standard ISO container conversions, this unit is purpose-built to a custom height of 2.9m (9ft 6in) and incorporates full electrical installation and a complete plumbing system as standard — both confirmed as included in the base build, making it one of the most comprehensively fitted units in our range. It is suited to remote office setups, backyard guest houses, ADU installations, and minimalist residential use where a self-contained, move-in ready unit is required.

Access is via sliding side entry doors positioned along the long face of the unit rather than at the end — a layout that suits sites where end access is restricted and allows the interior to be arranged without a clear end-wall entry path. Triple-glazed windows and doors are fitted throughout, providing a higher standard of thermal insulation and noise reduction than standard double-glazing — particularly relevant for year-round residential or office use in climates with significant temperature variation. The triple-glazed specification contributes to the unit’s energy efficiency alongside optimised wall and roof insulation.

The full electrical installation includes wiring to standard codes, outlets, lighting, and a breaker system. The complete plumbing system includes water inlets and drainage fully integrated, ready for kitchen, bathroom, or sink connections on site. Mains water supply and waste drainage must be connected on site by a licensed plumber. Mains electrical connection must be arranged by a licensed electrician. Interior finishes, layouts, and add-ons are customisable at time of order — confirm your specification with Atlas Container Supply before placing your order.

Note on US regulations: This unit is subject to local zoning, ADU ordinances, building permit requirements, and utility connection standards that vary by state and county. Confirm all permit and compliance requirements with your local authority before ordering. For reference, see the US Department of Housing and Urban Development manufactured housing guidance.

Construction & Durability

The 20ft office unit is built from factory-fresh one-trip steel — corrugated Corten panels that weather to a stable oxide layer instead of rusting through. Corner castings are forged and welded to the rails, so it can be lifted, stacked, and relocated without the frame racking out of square.

Delivery & Site Preparation

We ship the 20ft office unit across the Lower 48 on a tilt-bed at no charge to you. Allow about 75ft of clear, straight approach so the bed can tilt and slide the unit off. Have the drop zone marked and clear on the day — the driver sets it once, and moving it afterwards means another truck.

Why Buy From Atlas Container Supply

Buying new means you see no wear at all: no dents, no patch welds, no previous cargo. We inspect, then we list — no surprises on delivery day, and 30 days to return it if it is not right. More options in Container Home Office and the full container shop.
