If you had a 40 foot square space room to create your own personal home gym?

What would be your bare essentials to have? What equipment would you absolutely want in there?

My personal home gym is ever changing as time goes by and it makes me think what others want/have. Those crossfit rigs look like a damn good idea

I think for me I would want a vaulted ceiling so I can strap on my Olympic rings and fit a climbing rope into the rafter. have stall bars hooked up to the wall next to all of my barbells and specialty bars. With a set of rubber plates and a couple Dumbells. 6 foot long parallel bars. maybe a GHR and massage table, because I'm going to be done after whatever the f*** I do in there lol
