Residential Container Modifications

If you can dream it, our container fabrication experts can build it.

From tack rooms to garages, we can convert shipping containers into anything you need. We’ll build your custom container to your specifications, so you can get the extra space you need for your home. The corrugated steel of containers is very different than typical home building. It requires special tools, jigs and expertise to get it done right.

Whatever your need, we’ve got the experience and resources to make it happen.
Here’s why you should choose us to construct a customized container for your home:

Provide Your Design & Specifications

Ensure that your design includes all specifications you need and everything else you want. It’s easier to start with as many features you want and narrow down the list as you go through the process, than it is to add to the list later.

Residential Containers to Modify

The possibilities are endless. We can modify containers into any size and custom build anything you need. You get the choice between cargo-worthy or one trip (new) containers for your custom container project. Cargo-worthy containers are wind-resistant, water-tight and typically spent 10 years carrying cargo. One trip containers have only made one cargo trip in their lifetime and are the newest possible option, as ISO shipping containers are not made in the US.

You will need to provide a basic design, so we have an idea of what you want. We can draft the rest of your design based on any changes you request; however, we don’t correspond with zoning and/or permitting departments. 

We ask that you pay 50% of the total cost of your container modification before we start construction on it. The final 50% is due before we ship it to you.

Modified containers come with an industry standard one year warranty.

We may buy back a custom container, depending on the type of modifications, the condition of the container, our current inventory and market conditions. 

We have engineers on staff who can provide basic drawings in the process of building your custom container; however, we don't provide engineered or CAD drawings. 

We use ISO standard containers in varying condition for modifications. Choose from wind and watertight (WWT) or one-trip containers, based on your needs and budget.
