Turn old tennis court into garden

Hello everyone. I wanted to give a progress report anyway. We looked at the house and saw many beautiful things but also some that leave big questions open. For example, probably rising damp in the facade, the house is not connected to the sewer system due to its secluded location, drinking water from its own source (who checks the water quality?), etc. I’m not going to list everything now. Regarding the tennis court: It is really in poor condition and in my opinion should be removed and a neat garden created. Outside of the court, there is mainly a slope, so not very usable. In my view, the court is asphalt and not concrete, as I originally suspected. (See photo). The effort for demolition and the costs should therefore be somewhat lower, right?

I don't know if I can or am allowed to operate such a device at all.

I don't know what profession you practice, but I could imagine that you will enjoy it. Even I, as a 55-kilogram woman at 1.70 m tall, like working with a demolition hammer ... and if you can do that while sitting on a small excavator equipped with a chisel, that's certainly just great. :)

@ Pinkiponk: That immediately gives me courage and anticipation.

I'll attach a few pictures of the facade. Does that look like moisture to you? Or just old and worn out?
