The first thing I thought when I saw this "now you see it, now you don't" kitchen in Germany is how nice it'd be to have the ability to hide a messy post-dinner kitchen with the press of a button, especially if you live in a studio apartment. I don't think that was their primary design consideration, but still. See more photos below:

The Hidden Kitchen by Warendorf measures five metres long and opens, garage door-style, to reveal a "working space with storage areas, shelving, extractor fan and integrated lighting." You can't really see the kitchen, so it's hard to know if it'd be practical to cook in. My guess is they didn't have a serious cook in mind when they designed this, but it still caught our attention!
