I think of them as cars. As your life changes you go from 2 doors, 4 doors, sliding doors (yes minivans) and then back to 2-doors or no car when you are older. Micro-apartments or tiny homes are great if you are young and single. Once you get married or start a family it would get pretty crowded and hard to keep neat and organized. My 2 year old can tear up 3 rooms in 5 minutes flat. It’s also nice retreating to your bedroom to call it a day away from all the other stuff.
It’s a lifestyle decision where you have to weigh in traffic, cost, family size, etc. Great for single people, challenging if you plan on having a family. The transforming apartment seems a bit gimmicky targeting a very specific demographic but I guess it serves a very specific purpose.
