Storage Container House Cons

In recent years, storage container houses have become a popular alternative to traditional homes. Known for their affordability, sustainability, and unique design possibilities, these homes have garnered significant attention from people looking for unconventional housing options. However, like any construction method, container homes come with their own set of challenges and drawbacks.

In this article, we will explore the cons of storage container houses, discussing the potential downsides that homeowners and builders should be aware of before deciding to embark on a container home project. Understanding these challenges will help you make an informed decision and weigh the pros and cons when considering storage container houses as a viable living option.

1. Structural and Insulation Issues

One of the biggest challenges with storage container houses is the inherent structure of shipping containers. While containers are designed to be extremely durable and weather-resistant, they are not initially designed to be livable spaces. This means that substantial modifications are often necessary to make them suitable for residential use.

1.1 Thermal Insulation

Shipping containers are made from steel, which can absorb and release heat quickly. This creates a significant issue for thermal comfort within the home. Without proper insulation, a storage container house can become uncomfortably hot in the summer and cold in the winter. The steel structure conducts heat and cold easily, meaning without insulation, the interior will likely experience extreme temperature fluctuations.

To solve this issue, homeowners must invest in high-quality insulation systems to regulate the temperature inside the container. Options such as spray foam insulation, rigid foam boards, or cotton-based insulation can help mitigate the temperature extremes, but these systems can add to the overall cost and complexity of the build.

1.2 Condensation Problems

Steel containers are prone to condensation due to the contrast in temperature between the exterior and interior of the container. Condensation can lead to moisture buildup, which can cause rust, mold growth, and wood rot if not adequately addressed. This is especially problematic in humid climates or areas with frequent temperature fluctuations.

To mitigate condensation issues, it is essential to ensure proper ventilation and moisture barriers are in place during the construction process. However, these additional measures can increase the cost and time needed for construction, making the build process more challenging.

2. Limited Space and Design Flexibility

While storage container houses are often marketed as a modular, customizable solution, the design limitations of a shipping container can pose challenges for homeowners looking for spacious or highly customized living areas.

2.1 Limited Size and Layout

The size of a standard shipping container is 8 feet wide by 20 feet or 40 feet long, which may not be ideal for those who require more spacious living areas. While containers can be stacked, combined, or modified to create larger homes, this process comes with limitations that must be carefully considered.

For example, combining multiple containers into one home requires careful planning to maintain structural integrity and provide adequate living space. The more containers you add, the more complex and costly the project becomes. Additionally, the interior space of a container is often quite narrow and may not be suitable for families or people who need large, open living spaces.

2.2 Limited Vertical Height

Storage containers have a standard height of 8 feet 6 inches, which can feel cramped, especially if you’re designing a home with high ceilings or large rooms. While some containers have high-cube versions (with a height of 9 feet 6 inches), the overall height still might not provide the open and airy feeling that some people expect in a traditional home.

In order to make the most of the available space, many container home designs incorporate lofts or multi-story configurations. While this maximizes the use of vertical space, it can also result in less convenient layouts, as stairs or ladders are required for access to upper levels.

3. Zoning and Legal Issues

Another significant downside to storage container houses is the zoning and building codes that may affect their construction, especially in urban areas. Local regulations can impose strict rules on the types of structures allowed, which can make it difficult for homeowners to build a container home on their desired property.

3.1 Zoning Restrictions

Zoning laws are often established to regulate the types of buildings that can be constructed in certain areas. These laws dictate the design, materials, and size of the structures that are permissible. In many areas, shipping containers may not be considered an acceptable building material for residential use. This is because they were initially designed for cargo transportation, not for long-term habitation.

Some regions may allow the use of storage containers for commercial purposes or accessory structures, such as storage units or temporary offices, but using them as primary residences may not be permitted. As a result, homeowners seeking to build container houses may face delays or may be required to go through a lengthy approval process.

3.2 Building Codes and Permits

Even if zoning laws allow for container homes, building codes may impose additional restrictions. These codes are in place to ensure the safety and stability of buildings, but they may not always be compatible with container homes.

For example, some jurisdictions require homes to meet specific standards for foundation, structural integrity, and safety. Modifying a shipping container to meet these standards can be challenging, and it may require significant investments in reinforcement, insulation, and plumbing or electrical systems. In addition, the approval process for building permits may take time, adding another layer of complexity to the project.

4. Rust and Corrosion

While storage containers are made of steel and are designed to withstand harsh conditions during shipping, they are still prone to rust and corrosion over time. Steel is susceptible to damage from water exposure, and without proper maintenance, a container home can experience significant deterioration.

In areas with high humidity or near bodies of water, the risk of rust formation increases, which can compromise the structural integrity of the container. Furthermore, corrosion can damage the exterior of the container, affecting both the appearance and functionality of the home.

To prevent rust, it’s essential to apply protective coatings or anti-corrosion treatments to the steel. These protective measures, however, come with additional costs, and regular maintenance may be required to keep the containers in good condition.

5. Upfront Costs and Modifications

Although storage container houses are often promoted as an affordable alternative to traditional homes, the upfront costs associated with building a container home can be higher than expected.

5.1 Container Purchase Cost

While used shipping containers can be relatively inexpensive (typically costing between $1,500 and $3,000 each), the cost of purchasing multiple containers for a larger home can add up quickly. Additionally, the condition of the containers may affect their price, as older or damaged containers may require more extensive repairs or reinforcement before they are suitable for use as a living space.

5.2 Construction Modifications

Containers are not designed for habitation, so significant modifications are usually required to make them livable. This includes cutting windows and doors, reinforcing the structure, adding insulation, and installing plumbing, electrical, and HVAC systems. All of these modifications can add substantial costs to the project.

For example, while a basic container may cost around $2,000, the total cost to convert it into a livable space could easily exceed $10,000 when considering labor, materials, insulation, utilities, and interior finishes. The overall cost of building a container home may end up being higher than anticipated, especially when considering additional features like landscaping, furniture, and exterior cladding.

6. Maintenance Challenges

Storage container homes require regular maintenance to keep them in good condition. This is due to several factors, including the vulnerability of steel to rust, the need for insulation upgrades, and the risk of condensation buildup. Over time, these issues can lead to additional costs and labor.

Some of the ongoing maintenance tasks for container homes include:

• Rust and corrosion prevention: Regular inspection and treatment of rust-prone areas.
• Insulation upgrades: Over time, insulation may need to be replaced or upgraded to maintain energy efficiency.
• Sealing and weatherproofing: Containers must be properly sealed to prevent water ingress and damage to the structure.
• Ventilation: Proper ventilation systems must be maintained to prevent moisture buildup and mold growth.

While traditional homes require maintenance, container homes often demand more attention due to their unique structure and the challenges associated with living in a steel container.

7. Conclusion

Storage container houses offer a creative and affordable housing alternative, but they are not without their drawbacks. From thermal and insulation issues to limited space and design flexibility, zoning restrictions, and the ongoing maintenance of the steel structure, these homes come with significant challenges.

While container homes can be an excellent option for those seeking sustainable, minimalist, or affordable living, it’s important to weigh these potential cons against the advantages they offer. By carefully considering the limitations and potential problems of container homes, you can make an informed decision about whether this type of housing is right for you.

Ultimately, with proper planning, modifications, and attention to maintenance, a storage container house can become a unique and functional home. However, it’s essential to be aware of the challenges to ensure that the project goes smoothly and results in a long-lasting, comfortable living space.
