These rooms comes with a lot of insulation. They are assembled ahead of time at a factory, and don't seem to lend themselves to carpentry. There's no place to attach anything to.

We bought the room because there is no access for a vehicle to our back yard. The crew carried the room up 14 stairs in boxes, bless their hearts. It' a a very nice room, considering the conditions under which they had to work.

I hadn't thought about the effect of the rat-a-tat tats bouncing around the inside surfaces of the room, but that's got to be a factor. Again, I think putting a solid door in and avoiding the room during a bad rain is the way to go.

We love dining and birdwatching out there.
