When you have a "clean slate" to work with on a brand new from scratch shop, I'm very much in favor of making things "look nice" just because that can create a cheerful and welcoming feeling to the space beyond the joy from the activity itself. IE, if I was starting from scratch, my floor would be a lot nicer than the "bare" concrete with scattered anti-fatigue matts like I have now. At a minimum, it would be painted; ideally, it would be wood. Whatever you choose to do, at least it will be easy to accomplish in blank space!
