10 Things To Consider When Designing A Shipping Container Home

Shipping container homes have gained popularity in recent years, emerging as a sustainable, cost-effective, and novel way to create personal living spaces. The repurposing of steel containers into livable homes signifies a recycling triumph, transforming a symbol of global trade into a modular unit for innovative architecture. However, designing and building a shipping container home is not without its challenges. This article provides ten key considerations for those who are venturing into the realm of shipping container home design.

1. Building Regulations and Permits

Every architectural project begins with an understanding of local building regulations and the acquisition of necessary permits. Shipping container homes are no exception. Some municipalities and jurisdictions have explicit zoning regulations about container homes, while others might view them as unconventional, leading to restrictions or even prohibitions. It is therefore vital to consult local authorities, understand what is permissible, and secure the needed paperwork to avoid any legal complications later on.

2. Shipping Container Selection

Choosing the right shipping container forms the bedrock of your home design project.There is a variety of shipping container dimensions; the most common being 20-foot and 40-foot lengths, with a standard width of 8 feet and a height of either 8.6 feet (standard) or 9.6 feet (high cube). The latter offers more vertical space, which could be desirable for certain designs.

In terms of condition, “one-trip” containers are generally recommended as they have been used only once and hence have minimal wear and tear. However, even within this category, containers can have dings, dents, or surface rust, so it is crucial to inspect your containers carefully before making a purchase.

3. Insulation

The steel structure of shipping containers is a strong conductor of heat, which can create an uncomfortably hot or cold living space depending on the climate. Hence, insulation is a crucial aspect of the design process. The choice of insulation material can depend on various factors, including your local climate, budget, and personal preference. Common options include spray foam insulation, panel insulation, and eco-friendly choices like wool or cellulose.

4. Preserving Structural Integrity

Shipping containers are designed to carry heavy loads, but the weight is distributed on the corner posts. When containers are modified by cutting openings for doors or windows, or removing walls to join units, their structural integrity can be compromised. Working with an experienced engineer or architect can help ensure your home design maintains the container’s structural safety. The professional can guide you on how much steel can be cut away, where additional reinforcements are needed, and more.

5. Laying the Foundation

The foundation supports your shipping container home, preventing it from sinking, tilting, or moving with the natural movement of the earth. The type of foundation used can depend on several factors, including the type of soil, the weight of your structure, local building regulations, and budget. Common choices include slab foundations, pier foundations, and strip foundations. Your architect or builder can guide you on the best choice for your specific situation.

6. Efficient Space Planning

With a standard width of just 8 feet, shipping container homes require smart space planning. Think about how you live and what spaces you need. Open plan designs work well, as do features like multi-purpose furniture, loft beds, or outdoor living spaces. Window and door placements are also crucial for creating sightlines and maintaining a sense of openness.

7. Plumbing and Electrical Systems

Installing plumbing and electrical systems in a shipping container home can be more complex than in a conventional home. Most often, these systems need to be installed before you add insulation and interior walls. The placement of fixtures and appliances should be decided early in the design phase to accommodate plumbing and electrical lines. Employing an experienced professional can help avoid costly mistakes or code violations.

8. Ventilation

An efficient ventilation system is vital in a shipping container home for air quality and to control humidity levels. This can be achieved with a well-designed HVAC system, but also consider using strategically placed windows or vents to promote cross-ventilation. You might also consider ceiling fans, dehumidifiers, or energy recovery ventilators depending on your local climate and the specific needs of your home.

9. Moisture Control and Corrosion Prevention

Steel, the material of shipping containers, is susceptible to rust and corrosion, making moisture control an essential part of your home design. This involves choosing the right type of paint and rust treatment for the exterior and ensuring your home is properly sealed. Additionally, the design of your home should prevent water from pooling around your structure.

10. Sustainable Design

Finally, the very concept of a shipping container home lends itself to sustainability, but there are many additional eco-friendly features you can consider. Solar panels can provide renewable energy, rainwater harvesting systems can supply water for gardening or flushing toilets, and green roofs can provide additional insulation and create habitats for local wildlife. Additionally, choosing energy-efficient appliances and fixtures, using reclaimed materials, and designing your home to take advantage of natural light and heat can all help reduce your carbon footprint and lead to long-term cost savings.

In conclusion, designing a shipping container home requires a blend of creativity, practicality, and a deep understanding of building principles. While the process can be challenging, the reward is a unique, sustainable, and cost-effective home that reflects your personal tastes and values. As always, working with professionals experienced in shipping container home design will ensure a safe, comfortable, and compliant home.
