Construction projects

At a couple houses not far from us there are major renovation projects going on.  Next to each one is a set up that may not be unique to Denmark, but it is not something I have seen before.

The lower lever is used for storage of materials and the upper level is an office for the workers or contractor.

I know what you are wondering, and no, I don't know where the port-a-potty is, even though that is what dominates sites in L.A.
