My suggestion would be to move - buy a new house - with a bigger footprint. That way, your attic space would be much larger. Used to live in Milwaukee on 55th Street. Had a wonderful bungalow with 5 bedrooms, 3 upstairs. When boys moved out, I had the whole floor except for the master to play in. Even had a walk-in closet in the hallway! Really miss the city - so much to do! Good luck on getting your space to work for you.
