In essence, while shipping container homes can offer a more affordable alternative, the final decision should be based on individual preferences, budget, and long-term goals.

To help you get a better idea of if a container home is right for you, let’s take a look at the cost of container homes; both DIY and ready-made properties. 

DIY shipping container homes

If you’re trying to reduce costs, then a DIY shipping container house is the way to go. Without having to pay for labor, delivery, and installation, you can save quite a bit.

Instead, you’ll do it on your own. On average, it’ll cost about $130 to $175 per square foot. So, depending on the size of the home, it can run you anywhere from $20,000 to $80,000.

As you can tell, this is much more affordable than buying a traditional house. 

Although you’ll save on expenses, building a shipping container home is no walk in the park. You’ll need quite a few skills and quite a bit of time to get it done.

Plus, you may have to invest in tools and other equipment if you’re not well-equipped from the start.

Prefab shipping container homes

If building a container home yourself isn’t your cup of tea, prefab (short for “prefabricated”) shipping container homes are a popular choice for many reasons:

  1. Quick Setup: Since they’re already made in factories, these homes can be set up faster than homes built from scratch.
  2. Cost-Effective: While not as cost-effective as DIY, they often cost less than traditional homes because they use repurposed shipping containers and are made in bulk in factories.
  3. Customizable: Even though they start as standard boxes, these homes can be customized in many ways to fit what you want.
  4. Space-Saving: Builders know how to utilize space effectively, taking advantage of every inch, even when there isn’t a lot of space.
  5. Portable: If you ever need to move, you can take your container home with you!
  6. Modern Design: Builders offer a variety of container homes with unique and modern designs.

In short, prefab shipping container homes are fast to set up, strong, and can be made just the way you want them. They’re a smart choice for many people!

Typically, a home built by a container home builder will cost anywhere from $40,000 to $200,000. That’s because the price per square foot is around $250 to $300

With that out of the way, Steel Blox can set off to acquire the necessary permits. It’ll use these to construct the home.

Moving on, ALS also provides luxury storage container homes to clients. These houses are sleek, durable, and, of course, incredibly stylish. 

You’ll have a lot of control over the interior and exterior of the dwelling. Although this comes at an additional cost.
