Mistakes in Designing a 40 x 8 feet Container Shop

Here are some common mistakes you should avoid when building a unique container design for selling:
Choosing the Wrong Container Size
The biggest mistake people make when building a container and needing a container design is purchasing a container of the wrong size. In fact, this is the most common mistake made by some container shop owners.
Most people build their shops using standard 8.6’ containers. This usually happens because many are unaware of the existence of high-cube containers, which have an additional 1’ of height. This high cube setting is very common for containers in size 40 x 8.
A standard container is 8.6’ tall, while a high cube container is 9.6’ tall. The added height of a high cube container is perfect for those who want a container shop with higher ceilings.
If you use a general-purpose container and insulate the ceiling, your remaining interior ceiling height will be only about 7’. With a high cube container, you can install insulation and still have a ceiling height of about 8’.
High cube containers are more expensive, but they are quite popular. In other words, when you consider the benefits of using a high cube container, the slightly higher price isn’t a problem.
Other people are surprised to learn that containers come in lengths beyond just 20’ and 40’, including 10’ and 45’. There are even some containers that are a few inches wider than the typical units, including 53’ and pallet-wide containers.
Choosing the Wrong Container Condition
Another important mistake people make is not considering the condition of the container they’re purchasing. Buying a used container is a great first step in starting a container shop modification project with a unique design. You also need to be prepared to make repairs if the container is less than perfect.
You’ll likely repaint your container. However, if you find a used container that’s been used extensively, you’ll also need to remove any dents or rust. Containers naturally rust and corrode due to age and the harsh conditions at sea and in ports, requiring more repairs.
Don’t buy a container without first inspecting and checking its condition, for example, on e-commerce sites or online. It’s crucial to check the base material of your container shop to maximize its performance.
Even if you already have a clear idea of the container shop design, unscrupulous service providers can easily crop out flaws from the image or make it difficult to recognize with lower-quality images. However, if you absolutely cannot see the container in person, at least obtain plenty of high-quality pictures and videos if you can’t physically be there. Ensure all corner joints are visible, and that the bottom and top of the container are visible and in ideal condition.
Using the Wrong Type of Insulation
Another mistake you should avoid is not considering the type of insulation suitable for your local climate. For example, in areas with frequent rainfall, you need to ensure the insulation layer provides maximum protection. The best option is to use spray foam insulation.
In very warm and dry climates, your insulation will help keep your container shop cool. This depends on many factors, such as the local climate, your budget, the age of the container, and the style of store you desire.
Most people agree that spray foam insulation is the best insulation to use in many situations. However, it’s not the best choice for every situation. There are many other types of insulation, such as insulation panels, blanket insulation, and even environmentally friendly insulation like recycled newspaper.
Choosing the right type of insulation is crucial. If you use the wrong type of insulation, or worse, don’t have any insulation at all, you’ll face many problems.
Cutting Too Much Steel from Your Container Shop
Another common mistake is cutting too much steel from your container shop. A key feature of a container shop’s design is its strength. In fact, you can stack several containers on top of each other when fully loaded!
Shipping containers are the perfect building material for quick and affordable construction. Unfortunately, some people modify and over-design shipping containers, cutting away large sections of the steel walls.
By doing this, you reduce the strength and structural integrity of the container. Doing so also incurs additional costs, as you’ll need to reinforce the container with steel beams. You’ll also need to weld the steel beams in place, further increasing your budget and time.
Choosing the Wrong Container Shop Builder
The final mistake is choosing the wrong container shop builder to build their shipping container shop. Many people prefer to build their own shipping container shops with overly elaborate designs. Those without the time or DIY experience often hire a contractor to construct the building.
When choosing a contractor, make sure they have experience building with shipping containers, or, at the very least, understand shipping container buildings and are passionate about constructing them.
The last thing you want is a builder who doesn’t understand shipping containers. This will waste time, money, and certainly won’t produce exceptional quality. Furthermore, make sure you choose a contractor who can follow the construction process throughout the project. You don’t want to use multiple contractors during construction, if possible.
