That's my situation, too.
I've got a huge attic (near 1k square foot) that I could put a 10x10 in, But there are so many issues with doing that. Temp. Control, running electric, and hauling water up three stories are a few of them. Having a big old (built mid-late 1800s) house is great, Until it comes to stuff like that.
Hauling water that far would not be fun lol. I love growing in the basement. The temps stay where I need them to all year long. It's one less thing to think about and to try to control. My tent is anywhere from 70-80 year round.
But growing in a space that big would be sweet though
