I plan on building our spare room into a catroom. It'll be open to the rest of the house most of the time, but may be useful if we need to catch cats or keep them contained for short periods of time. We try to keep our whole house cat-friendly, though, so there's no additional need to shut them in if we aren't home, and being that we have 4 (large) cats with specific needs, no amount of vertical space in one room will keep them comfortable.
I think you know your cats best and if they aren't exhibiting symptoms of unrest, and they are playful, healthy animals, there's nothing wrong with how you manage your cat room.
