Concrete then fills the cells and 1/2″-thick steel plates are embedded into the concrete at the corners to secure the incoming ISBUs. This was before we had even installed the windows.” Attaching the Home to Its FoundationĪ shipping container house sits on a traditional concrete block foundation. A 40′ x 32′ stem wall foundation is set and reinforced with steel rebar.

“We had an open house one day when it was 85 or 90 degrees out and the air was at least 10 to 20 degrees cooler inside. “It really worked,” says Shannon Locklair, project superintendent for the North Charleston house. Supertherm is a high-performance, four-part ceramic coating that carries an R value of R-19 and adheres to the steel surface of the shipping containers. TAW uses Supertherm insulative coating, which is sprayed on both sides of the remaining container walls to prepare the house to save on energy that is used to heat and cool the house. Openings are cut into the outer walls for doors and windows. The vertical steel support beams are left in place for load-bearing purposes, with five along each remaining side of a container. In a home where four containers are to sit side by side, all but the outermost side panels are removed so that, once connected, the ISBUs create an open 40′ x 32′ interior space.

Once there, the house blueprints are reviewed and each unit is custom-fit for construction.

TAW starts by shipping the containers to their Tampa factory for modifications. When opting to build with ISBUs, the building blocks are readymade and ready to transport. They used four 40′ x 8′ x 8′ ISBUs laid side-by-side to create a three-bedroom home, measuring 1,280 square feet, without a hint of its original corrugated-steel exterior of the container. In North Charleston, SC, Tampa Armature Works (TAW) and local contractors quickly and easily constructed a container house, blending it perfectly into the surrounding neighborhood. They can be used to build an average-sized home with almost no wood. These intermodal steel building units (ISBUs) are manufactured in a factory-controlled environment so they are standardized and reliable. Shipping container homes, also called storage container homes, offer a fast, green, and sustainable approach to building.
