BMX Habitat

This is not bmx and it's probably already been Defgripped eons ago, but it does involve transitions and if you just shift your focus to the word "Design" in my title tag, we're even safely on topic...

It's a house in Athens that is designed to be fully skateable. It's by some architects called Archivirus and if you were to upsize it all x3 in some warehouse space or just apply the same principal inside the hellish shell of an Australian McMansion you might even be able to ride a bike in there.
