Finish construction documents for your shipping container home and submit to building authority for permitting. Submit construction documents to factory for pricing and engineering of container modules. Clarifications to building authority and factory as required . Get required permits from building authority. Submittal of construction documents to general and sub contractors. Execute purchase order of container modules from factory. II. The Build Site Work Begin grading work including any required excavation for foundation, utilities, storm water management, and septic. Bring required utilities to site. Install septic system and any storm water management system if required. Foundation The foundation shown below is a typical slab on grade application for a 1000sf (three 40′ containers) shipping container home design. There is a 24′ x 40′ perimeter foundation wall made from precast concrete panels, but could easily be cmu block or poured concrete. The perimeter was excavated and trench filled with gravel (for drainage). The precast panels were dropped in via a crane and tied together. The panels included insulation and exterior water proofing membranes added at the factory. Utilities (water, electircal, and gas supply lines) are run to the base of the foundation and then to there respective locations in plan. Foundation walls were then back-filled, soil compacted, gravel added, rebar laid out, and then slab poured. The Shipping Container House Foundations link in the Reference section has information on other foundation options and design. Container Modifications Shipping containers have monocoque bodies. The corrugation panels (roof, sides, and back), floor, purlins, front doors, frame, and rails form an integrated structural skin. They are strong and made to carry floor loads far in excess of what is required for typical home construction. But, when you modify them, cutting holes or penetrating members, they are weakened. Regardless of what level of modification your shipping container home design calls for, it is recommended to review with a structural engineer or architect. As we said above, when cutting a shipping container or removing any of the paneling, it’s structural integrity is compromised. As an extreme example, consider the removal of all a container’s corrugated paneling along the length of one side (see the images below). Without reinforcement, the container deforms and then fails structurally. As a general rule, whenever you remove portions of the panelized corrugation, steel framing will be required to frame out the opening. In addition, column and roof support will be necessary depending on the size of the opening(s) and roof/wind loads. Steel cutting, framing, and welding is a large part of shipping container home design and construction. Typically, steel construction is not used much in single family or smaller home design because of expense. Cost of steel vs. wood/light guage framing is substantial and the labor cost for steel vs.carpentry is also higher. To combat this, it is best to have as much of the welding and reinforcing done off-site before setting the containers on site and starting the interior fit-out. Most (if not all) container re-sellers have the facilities to make these modifications. If you don’t have experience in metal work, or are not hiring a general contractor, you should plan on doing most of the container modification work off-site prior to delivery. More information on Cor-Ten steel (the weathering steel shipping containers are made from) is available at the CorTen – Shipping Container Weathering Steel link in the RSCP Reference section. The Shipping Container Structural Components and Terminology link has more detailed information on the structural components of a shipping container. The Shipping Container Plan and Section Details link has more information on container to container connection details and framing on opening in the corrugation. Set and Secure Containers to Foundation and Each Other When the shipping containers arrive on site, they are crane-lifted one by one onto the foundation, hooked into place, and welded down to marry them completely to the foundation. These heavy-gauge steel containers are so strong—each is designed to carry 57,000 pounds—that they need only be fastened at the corners to hold fast, much as they would be on a ship. In the example above, the shipping container bottom corner blocks are welded to steel plates imbedded in the concrete slab to secure the house to the foundation. All corner blocks are welded to each other to secure the containers to themselves in the image below. Install windows, exterior doors, flashing, and any sky lights. Windows are set into openings that were measured and cut prior to delivery of the shipping containers or roughed out on site. All openings for windows and doors should be framed with a steel section. Hollow rectangle sections work the best, but an L section will work as well. Images below show openings for sliding door systems in the end and sidewall panels of a container. The Shipping Container Plan and Section Details link has construction details for window/door framing, flashing, thermal breaks, and glazing. Install interior framing, insulation, heating and cooling systems, plumbing, electrical, and rough out all fixtures. Supertherm insulative coating, is sprayed on both sides of the remaining container walls. 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. A ½- inch plywood floor over the existing ¾- inch plywood sub-floor is installed. Metal hat channels for wiring are run along the walls and vertical support beams are secured. Metal studs and drywall are used for interior partition walls. Once insulated, the existing container walls are faced in drywall for finishing. Install fixtures. Finish grading and landscaping. III. Inspection and Sign-off Staged inspections through the build with contractor and building official – foundation, plumbing and electrical, architectural, and fire. Put together final check/punch list for contractor Review punch list with contractor Final inspection with building official for certificate of occupancy How to Build a Shipping Container House: Conceive It.

Dani Dear Tom, I am planning a 20×10 container farm house and your thread really has extensive information and appreciate your effort. Now my worry is all about the tropical weather conditions in my country, Malaysia where day temperatures are high and it rains almost every week….my plan obviously includes giving the container a half meter high roof to protect from rain and tropical sun…..but do you think i would need to invest in insulating the container inside out? I have no done projects around here to visit and see how it feels in a container home and from my readings insulating in a later stage start living is a big pain as you need to redo the electrical and sanitary jobs…please advise. thanks Dani Malaysia Reply

Tom, I’m taking your advice and beginning with a plan. How I insulate will affect the overall design….form follows function I guess. I really love the look of the raw container. Something like the container of Hope by Garcia. If I use spray foam insulation on the inside, will the roof hold up to the elements or do you recommend building a secondary roof on top of the container to both add some slope and to add longevity to the container?

Wade 4. Sunny New Zealand Beach Home Number 4 is not a shipping container, it’s custom made. mari gorgeous. troy miller Interested in knowing more. ADavis I just read a site that talks about how much prep goes into a container home. Sand blasting for lead paint and replacing the flooring. The floors are chemically treated for rodents when used for shipping. Also the cost to cut openings, etc. Isn’t cheap. Abbett Survid All absolutely stunning but however my favorite is #10 because it has such a high ceiling not like any other conventional shipping container homes. Tony Adams have you tried google.com?
