After the room got built (and for some reason I don't have any pictures of just the bare room), it sat for several months. In November, I had three tons of drywall delivered through the windows on the second floor. Two guys took the sheets off the crane, and carried them through the guest room, through the bath room, through the pub, and stood them on the perimeter walls in the room. Definitely worth the price of delivery!
You can also see a mini split in the last photo. That was quite a challenge. As I mentioned in a previous post, there was an air handler in the attic above the gym, that heated/cooled the gym and one of the garages. But terminating the ducts into the garage is a code violation. The theater was going to go right where the old unit was, so it obviously had to go. But I needed HVAC in the garage, because I use it as a wood shop, and I don't want rust on everything. Plus I prefer to do that hobby in some semblance of comfort.
I had a four-head mini split installed. Ductless, it can be used in the garage. So I put a head in the gym, one large one in the garage/shop, one in the theater, and a fourth one in the pub. The pub is at the end of the run, so it tends to get less of the central air than other rooms. So the new mini split head works as a booster of sorts. Was less than $1000 difference to add the fourth head, so I went ahead and had it piped in with the rest of them.
And that is where the room has stayed until the last week or so. A bare storage room with a mini split HVAC and a single light bulb.
