Back in 2008 i worked at a Leibnitz institute in germany. First as a Wissenschafter and then as a Koordinator.

In the first case I shard a closed door office with one other person. Each of us had a large desk, bookcase and great space.

In the second case I had my own office with my own desk and even a table with two chairs for receiving people.

I was pretty low in the institute food chain. Only the PhD students were lower, and they shared 2 or at most 3 person closed door offices .

Its perfectly doable.

Thats because those buildings have a different public budget than personnel in germany
