At one of my home routes I can see this tower on the top of a hill. It is a old water tower, reconstructed with three flats at top now. All are 100 qm with a southside balcony.
Must be cool to live there.
Round my way the thing to do to water towers is to turn them into faux castles.
I suppose that's the big difference between Britain and Germany; we're still living in the past...
