20ft High Cube Custom Shipping Container Conversion — Anthracite Grey, French Doors & Roller Shutter (New)

Description

The 20ft High Cube Custom Shipping Container Conversion from Atlas Container Supply is a rugged, wind- and watertight steel unit engineered for secure, long-lasting performance.

This 20ft high cube custom shipping container conversion is a new, built-to-order modular building on a high cube 20ft COR-TEN anti-corrosive steel container base — 9ft 6in external height versus the standard 8ft 6in — providing a full additional foot of internal headroom throughout the converted space. The high cube base is the preferred choice for residential use, hospitality units, creative studios, and any application where the extra vertical clearance improves comfort, allows taller interior fit-out elements such as mezzanine shelving or full-height kitchen units, or simply creates a more spacious feel within the same floor footprint.

The pictured example is finished in Anthracite Gray externally and white internally with chrome container handles, and features the same glazing and access configuration as our standard height version — a manual roller shutter door (2,000 × 1,000mm) with bullet locks, double-glazed anthracite gray French doors (2,000 × 2,200mm), a large fixed double-glazed window panel (2,100 × 2,200mm), and a high-line opening ventilation window (1,800 × 400mm). In the high cube configuration, the additional 1ft of wall height above the French door header gives the facade a more imposing profile — particularly effective for hospitality, retail, and residential installations where visual impact matters.

The base build includes an insulated floating floor system as standard. Wall and ceiling insulation, electrical installation, climate control, plumbing, interior finishes, and branding or cladding upgrades are all available as additional packages. The high cube configuration is also better suited to retrofit insulation packages, as the additional ceiling height accommodates insulation and lining depth without reducing internal headroom below a comfortable working or living height. Specify your requirements at time of order for an itemised quotation. For guidance on container conversion planning and building regulations in the USA, refer to the International Code Council building standards reference.

20ft High Cube Container Conversion — Dimensions

Internal dimensions are pre-lining estimates. Finished clearances will be reduced by insulation and wall lining packages — the additional height of the high cube base makes it the recommended choice when a full insulation and lining package is specified. Confirm finished dimensions with Atlas Container Supply at time of order.

Construction & Durability

Every panel on this 20ft office unit is factory-fresh one-trip steel, formed into corrugations that carry load across the wall rather than through it. That is why a container this size can be stacked several high fully laden and still open cleanly on a level pad. The high-cube profile adds a foot of interior headroom over a standard-height unit, which matters for racking, tall pallets, and any fit-out with a ceiling.

Delivery & Site Preparation

Your 20ft office unit arrives on a tilt-bed and is placed directly on your prepared pad. Allow about 75ft of clear, straight approach so the bed can tilt and slide the unit off. Overhead clearance is the detail people forget: branches and low lines will stop a tilt delivery cold, so check the approach as well as the pad.

Why Buy From Atlas Container Supply

Buying new means you see no wear at all: no dents, no patch welds, no previous cargo. That grading is the whole point: it tells you what you are paying for. Cross-shop Container Home Office, or start with the buyers guide if this is your first container.
