About the 40ft high cube conex box
A high cube container is built like a standard unit but stands a foot taller, at 9′ 6″ instead of 8′ 6″. That extra headroom adds roughly 12% more interior volume without taking up any more ground space.
The added height makes it the favorite for conversions such as offices, workshops, and container homes, because there’s room for insulation, lighting, and ceiling finishes while still leaving comfortable standing room.
Why 40ft?
Twice the floor space of a 20ft unit for well under twice the price, making it the go-to choice for large inventories and conversions.
What fits
About the contents of a three- to four-bedroom home, or roughly 20 to 24 standard pallets.
Who buys a 40ft high cube conex box?
Best for: container homes, cabins and multi-room offices; workshops with tall equipment or overhead lighting; high-volume storage of light, bulky goods; and racking systems that use the full height.
Builders usually prefer new (one-trip) 40ft high cubes for living spaces because they arrive clean and straight, with fewer dents to fix. For storage only, a used unit costs less; see used conex containers. Need more length? The 45ft high cube adds another five feet.
