Buildings on water?(PIC included)

I have a friend in my town who has managed to put all his casinos on water tiles with no horrible pavement or grass underneath it. It is literally sitting on water. Does anyone have any idea how this is done?

It’s been possible in limited instances to place certain buildings on Squidport tiles and then subsequently remove the tiles. One used to be able to do this, for instance, with the Impossible Tower. Not sure whether this same strategy can be extended to other buildings.
