Mmmm,

I'm a huge fan of eco-brutalist architecture, so something with a lot of exposed raw concrete and steel, but also lots of moss and vines and ferns and stuff.

Enough room for a nice dedicated workshop and office space, and to have a bunch of friends over for hacking on things, but also small enough to be cozy when there is not many people there.

Ideally somewhere that stays decently chilly all year round, I'm not a big fan of the heat :v
