I have one slightly smaller one (180sqft) and while I still have yet to live in it full time (it's a WIP) it already feels claustrophobic sometimes. Every inch counts, but it's also important to have open-ness outside the tiny home too.

What I really wanted was the ability to experiment with so many things I would not be allowed to do in a traditional home, without worrying about blowing a bunch of money or hurting a $200k+ home I don't own/have a mortgage on. There's a lot I inherited from the previous owner, but it'll have custom automation and control software for the climate (dehumifier, heat exchanger, monitoring of power usage, etc), my dream programming space (converting the previous owner's "balcony" into a sort of indoor/outdoor deck with a massive transparent rollup door), and integrating more screens into my life (controlled by me, not loaded with any proprietary stuff that will inevitably hurt me).

But it's also just me and my cat. I've told partners already that I don't think I could live in this with anything more than that.
