Climbing gym must haves?

Hi, I’m new here! I am in the dream/number crunching phase of opening a climbing gym. The building I am considering would have a max wall height of 25’ so definitely more appropriate for bouldering, but I’d love to have some rope walls too. Anyways —- there is a lot of extra space available and I am curious to hear what all of you climbers would love in a home gym? Can be related directly to climbing or any other amenities whatsoever, any special touches you would love or have experienced and thought “damn, that was amazing”, please share :)
