Container home cost per square foot: how to calculate it honestly

Cost per square foot is the number everyone asks for, and it is easy to make it look better than it is. The answer depends on what you include in the total and which area you divide by.

Count everything, not just the box

A fair total includes the container, delivery, foundation, utilities, permits, insulation, finishes, and any site work such as a driveway or drainage. Leaving out any of these makes the per square foot figure too low.

Pick the right area

Use the usable interior floor area, not the footprint of the boxes. Walls take space, and a container has thick walls with insulation inside them. Be consistent when you compare two options.

Compare like with like

A container home with a simple finish is not the same as a custom stick-built house with a stone exterior. Compare two houses with the same level of finish, the same climate and the same number of bathrooms.

A quick method

1. Write down every cost line, including the unglamorous ones.
2. Add a contingency of about ten percent for surprises.
3. Divide by the usable interior area.
4. Repeat the same steps for each option you consider.

The container home cost calculator gives a total by section, which makes the division easy. For the basic sizes and what they mean in practice, read shipping container dimensions.
