There's a similar issue with mills. Many water mills and some windmills 
are now private homes. I've tended to put these watermills in as 
building=mill because they are such distinctive buildings, and it 
explains why a stream goes through it!

Some of you may be familiar with this building on the Suffolk coast:

(doesn't seem to have been put on OSM yet). It's the other way round - a 
water tower disguised to look like a house!
man_made=water_tower, building=house_like ???!
