7' tall ceilings x 32' long x 12.5' wide
It's a fully in-ground basement with ground-level half windows scattered around the exterior cinderblock walls. WHen you walk downstairs, you walk into the finished portion which is the band room / theater / listening room. In the back corner of this room is a laundry room. Walking straight through the door into the theater room you can walk into the unfinished area which the oil tank, furnace, air handler, and fuse box. The theater room is not fully sealable at this point.
Front, right side, and back walls are white painted cinderblock. Left wall is thin drywall (back side is open studs). The block in the rear is leaking slightly and needs to be fixed from the outside. i have three ceiling-height half windows.
Poured concrete with drains underneath high traffic carpet. Not much foam. Large, high pile area rug covering listening area floor.
Plasterboard with textured white finish. There's some unnecessary HVAC ducting that juts into your head clearance—with only 7' ceilings (rancher built in 1950) all that ducting is going to be removed and I'm going to redo the ceiling so it's flat throughout. The basement stays a comfortable temperature anyway in the summer so the vents down there are useless.
