Tiny living is the norm today but very many people have different definitions of what a tiny home must look like.

The best definition of a tiny house is any house below 400 sq ft.

So, if you are trying to downsize, you better think of a home that’s 400 sq ft or 37 sq meters or even smaller.

Contrary to what many people think, it is very easy to live comfortably in a tiny house especially if you are a startup couple, a small family, a retiring couple, or just a sole person that wants to minimize the cost of living and maintaining a large house.

It’s important to note there are more people on the planet more than at any other time.
