I visited this house only two months ago in Kaszuby. In fact, I posted one of my pics in the photos section of this forum but it didn't receive much attention
URLThe upside down house wasn't built purely as a tourist attraction. It's actually a clever piece of marketing for a company called Danmar who specialise in the construction of timber frame houses. They've created a "showhouse village" showing different examples of the type of houses they can build.
The "village" has become a tourist attraction it it's own right and is a nice way to spend a couple of hours. They have guides who show you round the place for a small fee. The "village" also contains a timber hall that houses the longest single natural plank of wood in the world (apparently it's in the Guiness Book of World Records). It tends to be used nowadays for large parties and dinners.
As for the upside down house it's a very weird experience. While you're waiting to go inside it's great fun watching people staggering around inside. Once inside you understand why as the place makes you feel like you are drunk. Just walking to the back of the house takes a great deal of concentration and completely messes with your balance !!!
Going upstairs is even more fun !
Well worth a visit !!
