I am building a small home studio and I try to not including anything that could distract me from doing my work and everything that supports me. This could be:

too much stuff, f.e. materials, canvases, furniture (distraction)

too less light (distraction)

inspiration, f.e. interesting objects like skulls, vases, sculptures (support)

well organized storage (support)

no or less noise, f.e. from the street or machines (distraction)
