Built to Your Specifications
Ark Container Rentals turns standard steel containers into custom-built shipping containers. They work for storage, offices, workshops, and one-off projects. We start with new or used shipping containers for sale or rent, then cut, weld, wire, and finish each unit to your plan. You pick the size, the doors, the climate setup, and the finish. We build it at our Kearny yard and deliver it ready to use.
Shipping Container Modifications We Offer
Ark customizes shipping containers with doors, windows, climate control, power, and security. Most builds start as bare steel and get fitted to your spec. Common options include the following.
- Roll-up doors: high-quality doors from 4 to 10 feet wide for easy walk-in or forklift access.
- Personnel doors: a 3-foot steel door with a lever handle and deadbolt for a second entry.
- Double-door and interior partition walls: split one container into separate locked sections.
- Windows: 3-foot by 3-foot units with security bars on the outside.
- Skylights and clear panels for natural daylight.
- Lighting: interior and exterior LED fixtures so the far end of a 40-foot container stays usable.
- Insulation: spray foam or fiberglass to hold temperature.
- HVAC: window units or through-wall systems for heat and cooling.
- Vents: turbine and louver vents that cut moisture without power.
- Refrigeration: reefer units for cold or chilled storage.
- Electrical packages: panels, outlets, and switches wired to code.

Container Sizes You Can Customize
Ark customizes 10, 20, 40, and 45-foot shipping containers in standard and high-cube heights. Every unit is 8 feet wide on the outside. High-cube containers add a foot of height for taller builds.
- 10-foot containers: about 75 square feet of floor and 560 cubic feet inside. Good for tight urban sites and small offices.
- 20-foot containers: about 150 square feet and 1,170 cubic feet inside. Our most requested size for jobsite storage and offices. See our 20-foot shipping containers.
- 40-foot containers: about 300 square feet and 2,390 cubic feet inside. Built for large storage and multi-room layouts. See our 40-foot rental containers.
- 40-foot high-cube: the same footprint with about 2,700 cubic feet and 8 feet 10 inches of interior height for ductwork and tall gear.
- 45-foot high-cube: about 3,040 cubic feet for the most space on a single footprint.
We can also cut units down to custom lengths like 15 or 30 feet, or join units for wider builds. Choose new, one-trip containers for a like-new finish, or cargo-worthy used units for a lower price. Both are wind and watertight. You can rent a custom container or buy one outright.

Superior Container Features
Ark builds on shipping containers because the steel is made to last. Every custom unit gives you the following.
Weatherproof Design
Containers are built to survive ocean transport. We seal each cutout to keep rain, snow, and heat out, so your contents stay dry.
Cor-Ten Steel Security
Containers use Cor-Ten weathering steel, a steel that resists rust and break-ins. Add lockboxes and steel doors for more protection.
Customizable Interiors
Tailor the inside with shelving, lighting, climate control, and partitions to fit the job.
Eco-Conscious Options
Ask about lower-impact upgrades like low-VOC paint and sustainable flooring on your build.

Custom Shipping Container FAQs
What Size Custom Container Do I Need?
Most office and storage builds start with a 20 or 40-foot container. A 20-foot unit fits about 150 square feet. A 40-foot unit doubles that to about 300 square feet. High-cube units add height for HVAC and tall equipment.
Can You Build Custom Container Lengths?
Yes. We can cut containers down to sizes like 15 or 30 feet, or join units for wider builds. Custom lengths limit road transport, so they fit fixed sites best.
Do Modifications Keep the Container Weatherproof?
Yes. We seal every door, window, and vent cutout. A modified container stays wind and watertight, the same as a standard unit.
Do I Need a Permit for a Container?
It depends on your town and how long the container stays. Many municipalities across New Jersey and New York require a zoning or placement permit for long-term or occupied units. Check with your local zoning office before delivery, since rules vary by site.
Should I Rent or Buy a Custom Container?
Rent for short projects and seasonal needs. Buy for permanent offices, workshops, or long-term storage. Ark offers both rental and purchase on custom units.
How Long Does a Custom Build Take?
Lead time depends on the build and container supply. Simple add-ons like doors or vents move fast. Full office or HVAC builds take longer. Call for a current timeline.
How Much Does a Custom Container Cost?
Price depends on the container size, condition, and the options you choose. Doors, windows, insulation, HVAC, and electrical each add cost. Request a quote for an exact price.
