What a modified container is
A modified or custom container is a steel container altered by fabrication. That can mean added doors and windows, insulation, electrical wiring, HVAC, plumbing, or interior finishes. The result is a building you can set on a site, not just a storage box.
What's in this category
- Site offices in 20ft and 40ft sizes, some with air conditioning, glass doors, a bathroom, or a solar power setup for off-grid sites
- Container homes, from compact 20ft units with a water tank up to 1-bedroom, duplex, and 3-bedroom modular builds with decks
- A 20ft insulated container greenhouse
- Larger custom builds such as a 20ft x 16ft modified building and a 24ft x 10ft site office or showroom
- A 40ft one-trip container with an added man door, a simple first step up from plain storage
Condition
Modified units in this category are listed as new, refurbished (professionally repaired, repainted, and serviced to working condition), or used. One unit is sold as seen. Read the condition and the specification on each product page, since fit-out varies from unit to unit.
Before you buy
Check your local zoning and building rules before ordering a container home or office. Many areas treat a habitable container as a building and need permits, a foundation, and inspected utility connections. Also confirm how the unit will reach your site, because larger and multi-story builds need more access than a single container.
If you only need secure storage, a standard dry container costs far less. Request a quote on any build and we'll confirm the specification, price, and delivery.
