I have an outbuilding with about 290 sq ft. I'd like to turn it into a rehearsal studio with a little space for tools and a workbench. I'd appreciate hearing from anyone who has done this or has even a partial design for how to do it. Thinking some reasonable way to soundproof the walls, plenty of electrical, light/skylight, 1/4 bath, what else will I want? Get as creative as you like. Gracias!
