Quick Answer
A 20-40 foot shipping container works best for full-time living, offering ample space for a comfortable interior while minimizing costs. This size range also reduces the need for excessive cutting and modifications.
Choosing the Right Shipping Container Size
When selecting a shipping container for full-time living, consider the balance between space, cost, and simplicity. A 20-40 foot container provides a sweet spot between these factors. For a single person or couple, a 20-foot container can be an ideal choice, offering about 400 square feet of living space. For larger families or those who desire more amenities, a 40-foot container can accommodate up to 800 square feet.
Insulation and Climate Control
Regardless of the chosen size, proper insulation is crucial for maintaining a comfortable temperature inside the container. Use a minimum of 2-3 inches of spray foam insulation on the container’s exterior and 1-2 inches on the walls, floor, and ceiling. Ensure the insulation is fire-resistant and suitable for the local climate. Additionally, consider installing a high-efficiency heating and cooling system, such as a mini-split or a heat pump, to maintain a consistent temperature.
Cutting Openings and Foundation Preparation
When cutting openings for windows, doors, and other features, carefully plan the layout to minimize wasted space and ensure structural integrity. Use a metal cutting saw or a plasma cutter to make precise cuts. For the foundation, consider a concrete slab or a gravel-based pier-and-beam system to support the weight of the container. Ensure the foundation is level and securely anchored to the ground to prevent shifting or settling.
