Building a home from shipping containers is an increasingly popular form of sustainable and affordable housing. Container houses offer many benefits including low cost, ease of construction, and durability. Two of their main appeals are their solid, enduring construction and long lifespan.

Shipping containers themselves are a durable material. They are built from corrugated steel that is 4-12mm thick and designed to withstand months or years of transport by ship, truck and rail. The steel exterior provides strength and weather resistance, protecting containers from UV rays, rain, snow and wind.

Common benefits of the solid, durable nature of container houses include:

Strength – The steel walls and reinforced corners of shipping containers make them very strong structures. They can withstand weights of up to 70,000 lbs and extreme outdoor conditions during transport. This same strength translates when they are used as building modules.

Longevity – Due to their durable design and construction, shipping containers are meant to be reused many times over. When outfitted as houses, container modules can last decades with proper maintenance. With regular upkeep, container homes may outlive conventionally built structures.

Weather Resistance – The steel exterior of containers protects internal spaces from sun, rain, wind and seasonal temperature changes. Even without additional siding or roofing, container structures remain weatherproof and hardwearing.

Reduced Maintenance – The solid, impenetrable design of container modules means less regular maintenance. Corrosion-resistant steel exteriors do not require repainting as often as wood siding. While still necessary, general upkeep tends to be minimal.

Despite their durable nature, additional steps are typically taken when converting containers into houses to improve comfort, functionality and aesthetics. Common modifications include:

Insulation – The steel walls of containers are insulated on the interior to increase energy efficiency, reduce noise transmission and provide temperature control. Various insulation types can be installed between wall studs.

Adding windows and doors – Larger windows, doors and sometimes skylights are installed to improve natural light, views and ease of access.

Interior finishes – Shipping container interiors are covered with materials like drywall or wood panelling for a smoother appearance and easier surface for attaching fixtures.

Plumbing and wiring – Basic systems for water, sewer and electricity need to be connected for a functioning home.

HVAC systems – Heating, ventilation and air conditioning are often necessary depending on the climate and intended use of the container house.

With careful planning and proper customizations, container homes can leverage the solid, enduring construction of shipping containers to create low-maintenance, long-lasting and sustainable living spaces. Their durable design coupled with relatively easy construction contributes to a housing solution that is built to stand the test of time. As more people recognize the benefits of container house longevity, this construction method has potential to reshape what is possible for creating affordable yet lasting homes.
