Hi there! I like your vision! Those will be really fun elements in the room. That wall looks like an old office/desk area? I think it needs an overhaul. Like take it all out and plan for something totally new that will meet your needs. Something with plenty of closed storage space. Or get rid of everything on that wall and just use an extra long storage cabinet to use under he tv.

the first step is to sort through what you have in that room so you can determine how much additional storage space you need. Right now, your existing shelves don’t have enough room, and installing the amount of cabinets you would need would turn your room more into a storage space than a TV room.
