A playful solution to the housing crisis  (transcript)
Summary
This talk is about how you can build your house. It's difficult to build it because it's expensive and many people don't know how to build better. Probably, you will try only one time in your life. You can't fail, however, you haven't experienced it and can't practice. Thus the speaker created a game. It's quite realistic and that you can build your own house in the game. It means that you can know many things before building your own house.
Whether the house is built from nontoxic components or not, and from light gauge steel frame construction or not. 1) How can you decrease construction costs by 20 percent? and environmental waste by 15 percent? 2) Of course, you can choose your chair and color for walls in the game. 3) By helping 3D printer, you can experience building a more high-quality house. 4)
It'll be wonderful that every person can build your own house the way you want, you design reasonably and quickly. This is a playful solution to the housing crisis.

I thought that the problems are that in Japan, building houses are expensive and I don't like playing games, though, there is another problem in Japan.
In fact, there is more than enough houses in Japan, but companies build to get more benefits. However, it doesn't become an affordable price because the government also wants to get benefits.
The common people are struggling.
