When you have been playing a little with the idea of how your new shipping container garage should look, it is now you must apply for a building permit. During the 14-18 years that containers are typically located on the oceans, various things have also been wasted in those that can cause indoor climate problems if the used containers are converted into housing.
The problems with harmful substances can of course be avoided by either sand blasting the used containers or by buying new ones, where you can specify how they should be painted and which floors you want in. One of the things we learned from our first office building to what we are doing now is that it is worthwhile to buy new containers. Although you might think so, containers are not just the same bricks. For a modern building where you have to have a very close facade, it can be a big challenge.
The extra time you have to spend on the construction site to fix the bumps can easily turn out to cost more than you should have paid for new containers. You can easily make an opening in a container or strip a whole wall away if you want to put more together. But if you start stacking them or need a lot of weight on top, then you need to use a lot of steel for reinforcements, because much of the force smokes when you start removing something.
