What are these pipes in garage for?

Hi all,

I recently visited a house which I am thinking about purchasing and renovating it. It has a huge garage with these weird pipes.

Before I ask the markler/gutachter, I was curious to know what these pipes are for and could they be moved outside the garage. I don’t have a car at this time and I can easily park the car outside on the road in the future. So I was thinking maybe I can convert this garage into a Wohnzimmer/Gym.
