does anyone know.....

i am building a simple 2 story home...i see when placing one on the top floor....the "inerds" of the hot tub come through into the first floor....

i was wondering if the "inerds" have to left unblocked or what for repair purposes....

i am just going to put a wall around it....but i needed to know if i
need to leave enough space or not....

You can build a wall around it.

thank you
