Great topic.
We are a developer here in Malaysia and we've looked at many options for housing. Ultimately price and value is going to dictate if people are interested. Most people here price things by square feet / square metres. And generally larger houses / apartments are better value by square feet / square metres. When you reduce the lot area, your price per feet generally goes up so its kinda difficult unless you 'lower the quality' somewhere. But if you can provide people with innovations then its possible to make it work. There are some 'ridiculous' prices on houses (some which I just don't think is even possible), 2 bedroom terrace house (joint to the next lot) goes for US$30k where they must have compromised on the quality.
As for the video in the OP, I would personally find it hard to live like that, as I'm more of a minimalist kind of person, in my 45 sqm apartment back in Australia, I had the following items - fridge, washing machine, bed, couch and tv (plus my consoles).
Also I think it depends on what stage people are at in their lives, I was fine as a single person living in a shoebox, but now with kids, I'd like more space for them to run around in. An apartment isn't what I'd want for them, though I know in Asia that is the norm.
As someone who's used a 'wet bathroom' for 3 years now, can I just say how much I dislike this concept coming from a 'dry bathroom'.
1. If you wear socks its terrible. Most people wear socks with shoes. If you take your socks off, you have to dry your feet after. If you go barefeet and wet afterwards, your feet get dirty really quickly from picking up dirt and dust around the house. I also have to avoid stepping in other people's wet footprints around the house. Wet footprints are a hazard (especially with children) with hard flooring.
2. Its terrible for guests, unless you provide them with sandals. Guest sandals are awful.
3. More grime around toilet due to showering.
4. Toilet gets in the way when showering due to small space.
5. Wet floors with bad drainage are not pleasant.
And we also have squat toilets here which are wet too, a hose is provided to wash the entire area down. Maybe I just don't like wet areas. I don't even want to provide a picture cause it sucks so bad.
People here I guess prefer larger bedrooms over a larger bathroom to maximise living space. I guess people don't want to sit on the can playing Nintendo games.
EDIT: Obviously in that photo, it looks well drained, but not all wet bathrooms are like that.
