Sweet.
I want one that doubles as a rehearsal studio, I knew of one of those in San Francisco.
Not counting the stairwell or foyer, the room itself is about 10’ by 13’ and 7 feet high.
It’s not for the claustrophobic.
It has 2 poles in the center for support, and a few triangular gussets emanating from the walls to strengthen the ceiling.
By today’s standards the poles and gussets are very, very anemic.
Judging by the hammock hooks welded into the walls, it looks like it was meant for a family of 3.
