Lots of people live in a small home, a small room or just a small space for a reason. But no matter what reasons people may have for living in small spaces, compromises and organization is the key to make everything fit and not cramped.
Here is an example of designing and building for living small. Just as small spaces can actually be harder to keep clean than larger spaces, they can also be harder to design because they require more clever attention to picky details.
This is also an example of being clever and conscientious while saving a lot, not only in construction, but on air conditioning, electrical bills, maintenance, furnishing and taxes.
