waltersalas,
We are in the early stages of having a new home built in the Biltmore Lake community, near Asheville. I suspect the new home won't be ready until the end of 2020, maybe into 2021. And yes, I am having a "bonus room" above the garage, 13'6" x 18'11".
I did find the Carolina Audio Society and will investigate that club when we are down in Asheville.
