Au contraire, you see, I can live quite nicely in a 1,000-square-foot apartment, but I need about 1,500 square feet of garage space for my hobby support, places to put my tools where they're usable, storing lawn equipment, recreational equipment, etc.
Now, if you add my partner, we could add another 1,500 square feet to the living space, you know, because of "stuff," and then we'd need to double the garage size for her art studio and project space.
And that doesn't include the space we use for a berry garden, fruit trees, and vegetables.
