How Many Square Feet Define a Tiny House? The Complete Guide

When exploring the world of tiny houses, one key question emerges: how many square feet define a tiny house? Typically ranging from 100 to 400 square feet, these compact dwellings blend clever design with intentional living, offering freedom from conventional space constraints.
