Multiple-use gone mad

I'm all for the multiple use of buildings, you know what I mean, shops on the bottom, then a floor of offices, then some apartments above for example, but this is ridiculous.

My office is on the ground floor, there is a flat on the first floor and a drum teacher on the second floor. They are practicing as I speak. When they first started banging away I thought perhaps it was a joke, but no.

The only worse thing would be violin for beginners.
