This tedtalk mentions about architecture kind of being a way to bring communties or families together by architecture. By this, everyone can get what they want, a place to be comfortable and suits their needs. This is important in a way to maintain societies neutral, since there are no "must do" when it comes to individuality. Let's think of houses as a self-expression or identity. People want to express and embrace themselves, that's why art was made for, to express visually what's within. I think societies could engage more if architecture was more suitable for each one of us. Some countries do implement this type of self-architecture. Believe it or not, in Latin America people design most of things by their own and have their spaces that match with them so they feel more comfortable.
