How Does the Size of the Container Affect the Overall Building Cost?
When it comes to container homes, offices, or any kind of structure built using shipping containers, one question seems to bubble to the surface more than others: how does the size of the container affect the overall building cost? Whether you’re a seasoned builder or just starting out with your first container project, understanding this relationship can save you time and money. So, let’s unpack this topic in a way that feels relatable and practical.
The Basics of Container Sizes
First off, let’s dive into the different sizes of containers. Shipping containers typically come in two standard sizes: 20-foot and 40-foot. The 20-foot container provides about 160 square feet of space, while the 40-foot container contains roughly 320 square feet. Seems straightforward, right? But here’s where the fun starts.
I remember when I was considering building a home office from a container. I was initially drawn to the 20-footer because of its lower price tag. But then, after sketching out my ideal workspace, I realized I’d be a cramped ball of frustration staring at the walls. If you’re aiming for comfort and functionality, it’s vital to think about how much space you actually need versus what might look appealing on the surface.
The Cost Impact of Size
Initial Costs
The size of the container directly impacts the initial purchase cost. A 20-foot container might set you back around $2,000 to $3,000, while a 40-foot container can range from $3,500 to $5,500, depending on factors like condition, location, and availability.
However, don’t let that initial price fool you. Buying a larger container often leads to reduced costs per square foot if you plan to use all available space efficiently. So, if you need a larger workspace or family area, investing in a 40-foot container may prove more economical in the long run.
Shipping and Delivery Costs
You must also take shipping and delivery costs into account. Shipping companies usually charge based on the container size and weight, so opting for a bigger container might bump up those costs. Imagine budgeting for your container project like budgeting for a vacation where you might have to account for luggage fees (the larger container) that could pinch your pocket a little more.
Modification Costs
Once you’ve locked down the size, the next consideration is the modification costs. Bigger containers require additional modifications and sometimes more complex design solutions. For instance, my friend decided to go with a dual 40-foot container setup to create an elongated living space. While it looked fantastic, the modifications such as adding windows, doors, plumbing, and electrical systems were much more complex and costly than anticipated.
Think of modification costs as the cherry on top of your container project. The more room you’ve got, the more cherries you may need, which translates to a higher overall cost.
Practical Scenarios
Let’s paint a picture. Suppose you’re a budding entrepreneur wanting to set up a caf\\u00e9. With a 20-foot container, you can fit in a small kitchen and a couple of tables, but you’d be limiting yourself on seating capacity, thus reducing potential customer income. Conversely, a 40-foot container could allow for a small kitchen, several tables, and even a cozy reading nook, making it a more inviting place and giving you better revenue potential.
Or, say you’re a family planning to live in a container home. A single 20-foot container might work for a minimalist lifestyle, but you run the risk of it quickly feeling cramped. If you’re a family of four like mine, the living space can become a point of friction. My husband and I opted for a combo of two 40-foot containers, allowing us to create separate living and recreational spaces that suited our family’s needs.
Hidden Costs
Ah, the hidden costs. With larger containers, sometimes there are unforeseen expenses that arise during the project. Zoning laws, adding insulation for energy efficiency, or even the need for more substantial foundations could all hit your wallet unexpectedly. Many first-time builders overlook these aspects but they can quickly add up.
When I built my container office, I overlooked climate considerations. I assumed one layer of insulation would suffice in my area, but when winter rolled around, I was in for a surprise. After numerous space heaters (and high electric bills), I knew I should have invested in better insulation from the start.
Conclusion: Size Matters

In conclusion, how does the size of the container affect the overall building cost? In short, it matters a great deal! From initial purchase costs and delivery fees to modification expenses and hidden costs, each element ties directly back to the size you choose. So, before you make a decision, take the time to reflect on your needs. Whether you’re building a cozy home, a vibrant caf\\u00e9, or a simple office, carefully consider how much space you realistically require and the potential cost implications. After all, building with containers should be an exciting adventure, not a financial burden. Happy building!
