Building a Building in a Tutere

We actually have a test shaft in a tutere which is 300 meters. And but it goes below the ground. In finland, everything is quite flat here. But we're testing out different user inte paces, or different icons and parts of user inter paces. So it's not always the there, like real functioning set up. But then as well, we have this kind of pilots sigts, where we go when observed to understand better certain kind of a building segment.
