Fantastic size !! :) Congrats!
Solid flooring, much easier cleanup :)
Like the idea of the wheels on the moveable tables, I like an Ironing Board moveable, so can be regular height or shortened for swivel and quick press. Consider sound dampening board for a wall can be covered and used like corkboard, much more reasonable $ too.
Graph out what you have, sizes of machines tables, space between, windows, doors, cabinets, and storage area. So hopefully will only have to position things once. Fill er up and get busy:) Enjoy !!
