New Shop/Studio Layout

I am building a new 12ft X 24ft space as my shop. I carve wax, cast,
make molds, etc. I have no employees, and don’t ever want to, but
maybe would like to take in 2-3 students at a time for 5 day classes.
I think I have a pretty good idea for a layout, but I would like to
hear from some of you folks that have been doing this as a career for
some time. (I consider myself a student/amateur). How would you pros
set up a shop given the mentioned parameters? Thx,
