Is there a house swimming?

During my stay in the Netherlands I watched some specific features.

I could look in the sitting rooms because there are often no curtains or I watched people eating a herring rolled in onions without bread.

One day a house overtook me while I was walking along a canal, nevertheless; when I stopped surprised, I recognised the boat pushing the swimming house.

Sometimes I saw old vessels which sailed on canals in former times without tacking.

I saw big sandy buildings in the city centre, just as gigantic plastics.

Often film teams were on the move.
