Is a foundation necessary for containers? If yes, how?

Hello everyone,

A office container is to be set up on an agricultural farmyard. The container is 6 meters long, 2.5m wide and 2.8m high. see photos of the container and of the setup location

The question now is whether a foundation is needed for it? Are there maybe people with experience here? Do you need a proper concrete foundation for it? Or are a few stacks of paving slabs sufficient?

I am grateful for any help! :)

How much does the container weigh? Normally, the manufacturer provides specifications for installation. However, I wouldn't make rocket science out of it and would just place the unit, like many others, on a few concrete slabs unless it is supposed to be raised by 50cm.

It is important that the substrate is suitable. So no sloping gravel that you then want to level out with a stack of five paving slabs. Otherwise, I would simply use a gravel surface, grit, paving slabs, as long as the manufacturer does not specify otherwise.

lived in a container on the construction site for a few months. The question is for how long and what is supposed to take place there. Living or storage or disco?

So the container is to be used as an office. So 1-2 desks and a few shelves with folders will go inside. It is supposed to stand for several (many) years. Maybe you could do, for example, 4 support points per side. So 8 in total and thereby distribute the weight over more points. Then there will certainly be fewer problems with sinking, right? A normal sea container of this size is specified with about 2 tons empty weight. If you add another ton of office equipment and distribute the 3 tons over 8 points, you have 375 kg per support point.

Normal sidewalk slabs 30 x 30 are sufficient (depending on the ground). However, I had 14 or 16 support points. At all corners, front and back, one each in the middle, and on the long sides 4 or 5 each (I don't really remember exactly). On natural ground, I had 2 to 3 slabs stacked on top of each other (our property is slightly sloping). Only removed turf and some soil according to the height and leveled the slabs. It held perfectly. The container stood there for about 1 year. It has now been standing on my son's property in the same way for 2 years.
