Such a curious work of architecture. I went to visit in the summer of 1999, but didn’t actually go inside one of the houses until 2011 on a return visit to Rotterdam.
I think part of the issue is that the house available for tour is not very well maintained, nor is it very well decorated on the inside. The exterior is kept in fairly good condition though.
The spatial experience created outside of the cubes themselves is very unique- probably one of the most futuristic community areas I’ve ever seen. Worth the visit for sure, but be prepared for some sci-fi figurines in a cabinet in an odd corner of the show house.
