20ft Pre-Assembled Container Home — Matte Black, Off-Grid Ready, Move-In Ready (New)

Description

The 20ft Pre-Assembled Container Home from Atlas Container Supply is a heavy-duty, wind- and watertight steel unit engineered for secure, long-lasting performance.

This 20ft pre-assembled container home is a new, fully built residential unit delivered ready for placement — no on-site construction or assembly is required beyond positioning on a prepared base and connecting utilities. Built on a heavy-duty alloy steel frame with a corrugated metal body and fully waterproof corrugated roof, the unit is finished in matte black and sized at approximately 19.3ft × 7.2ft — a narrower profile than a standard ISO shipping container, making it suitable for tighter residential lots, backyard ADU placements, and remote sites with limited access width.

The interior comes pre-installed with doors and windows, built-in flooring, a fully installed roof system, and a kitchen area with cabinets and sink. The kitchen is appliance-ready — cabinetry and sink are fitted, but cooking and refrigeration appliances are buyer-supplied. Large windows provide natural light throughout the interior, and high-performance insulation with integrated ventilation is built into the wall and roof construction for year-round thermal comfort in both hot and cold climates.

The unit is designed for off-grid and grid-tie compatibility, with optional integration of solar panels and wind turbines available at time of order for buyers seeking energy independence. Confirm electrical and plumbing installation specifications with Atlas Container Supply before ordering — neither is explicitly confirmed as included in the base build and must be verified prior to purchase.

Note on US regulations: Container homes and ADUs (Accessory Dwelling Units) are subject to local zoning ordinances, building permit requirements, setback rules, and utility connection standards that vary significantly by state and county. Placement on land does not automatically constitute lawful residential use — confirm 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.
