How can someone live in so little space?

Do this exercise when considering a tiny home: Determine where you spend the most time in your current residence. Measure the exact space that time occupies. For most people, it’s a bathroom with shower/tub, bed, sofa with table and chair, kitchen table, kitchen appliance area, and maybe a porch. These spaces are easily accommodated in a 400 sqft tiny house. You can then adjust space requirement up or down based on your personal preference, and whether you intend to live in the space full time or keep it as a home base for outdoor activities
