I'm pretty excited about my new room i'm building

I am fortunate enough to be getting kicked out of my dedicated audio space 12’x16’x9’ to make space for the kids to have separate rooms .I am remodeling a stand alone building on my property.The dimensions are 16’x24’x9’ with 10"thick cement floor.I am open to either treating and painting the floor or a floating pergo style floor ( no carpet ) with floor rugs .the walls are drywalled 2x6 construction insulated with redwood board and batten exterior, above the ceiling is insulation with open attic area(which I could add more insulation). As a few of you know I am fully off grid and generate my own power thru solar and gen backup into large battery banks then inverted to my house etc.The only furniture per say will be three reclining chairs etc .I will transfer a lot of my treatment panels and add more as needed. Also I will be trying to set up a humidity and temp control for this room when not in it, I was thinking 60deg 60% humidity .thoughts?
Any tips or thoughts are appreciated .
Thank Ray

I still will have my home theatre setup which is pretty nice in the house also so i’m stoked .
I have a room (below grade) on a slab here in Portland, OR. It had an engineered cork floor, installed at the suggestion of the contractor. It was really gorgeous and softer and warmer underfoot than wood or Pergo.

Water vapor passes through any concrete slab. Over time, water vapor condensed below the floor, saturated the underlayment, and caused problems that proved costly to fix.

Unless you are in a dry area and your outbuilding has a perimeter drain and excellent moisture barrier, I’d be very careful about any flooring that won’t let the water vapor through. There are products made to raise flooring off the slab, and I guess they are used in commercial construction, but I am uncomfortable having moisture accumulate at all. However, they would let you use Pergo or something like that.

We had the slab ground down, a densifier applied, and eventually settled on an all-synthetic pad and carpet for the room. There has been no further moisture problem. Any water vapor is taken up by dehumidifiers (set to 45%).

I am not an engineer, and I can’t provide real construction advice -- this post is meant just to alert you to issues you should discuss with a specialist in on-grade flooring. In my experience, a general contractor and the floor manufacturer were NOT reliable sources of advice.

I don’t want to forget: Enjoy your space! It’s wonderful to have one that large!
I'm seriously considering treating the floors and do some type of paint on them and just using large throw rugs
