Could you, would you, live in a tiny house?
Most of them are just too small for me, but I like this one a lot.

I'd attach the second one and use it as a bedroom. I'd want it to be the same size as her main one. Cool idea though, since she's a musician, to have it as a gigantic amp, with space inside to write and practice.
I'd also want a big comfy outside space. Similar to hers, but with comfortable outside couches, and covered.
