Do you have children? Or a dog? It is usually a good idea to have one extra room per each member of the family. This way if you want to be alone for a while you can. Or if you want to listen to the music that others don't appreciate you can (headphones can be tiresome to wear).

Sharing a room with a brother is not that bad. You just learn to share the spaces. If I wanted to be alone, I usually took a walk.

plenty of cultures don't generally have room to be alone at home. Not saying I don't like the idea. Just pointing out that depending on where someone grows up the idea that they might have alone time at home might seem strange.

Could you name me some of those cultures? What interests me is given the choice would they want to have extra space or not? IMHO good indicator of it is how their rich live.

Baseless. Start it with "I like..." and then it's true.

Maybe it is baseless but I wanted to give a little perspective, to show that it's not always about your wishes. If you live with someone you have to accommodate for their needs as well.
