OK, I not der, so I gotta go wid information available on charts like such
Average Weather in Gunter, Texas, United States, Year Round - Weather Spark

I see you don't get cold or really hot,
Dis site says you got pretty average 20° difference between day and night
Gunter, TX Weather - Forecast & Monthly Averages

Put both together and you got good potential fer natural cooling.
Both say you got lot of rainfall for cooling if you use cistern to store water.

Concrete slab gonna act as pretty big thermal battery stay around 60°.
Floor probably also gonna be BIG problem hauling humidity into room from ground cause not properly isolated from ground. Epoxy on top only minimal value UNLESS carried onto wall to isolate floor. Gotta connect floor seal to foam seal.
You already past halfway point of building giant liferaft still.

Insulation on bottom of deck not gonna be much help due to minimal differential above & below. Drywall big PITA and eats deck capacity.

You not say what woman does in her shop. She wants sail loft you got 1 set of problems, she builds deck furniture and dog coffins complete different set. Much better you build to need den rebuild to get up to need.

Dehumidify inside meat locker fool's errand by power company friend. Better to work with Mother Nature den fight de old battleax.

Oh, no, they are noisy!

Finishing the space to her wishes won't make a lick of sense practically speaking. (Generic Comment)

Cost be dammned, Employ an air forced HVAC system and heat recovery as you would any modern home.

Nice Looking Room. No doubt about that.

EDIT: Thinking about this for a bit. No doubt in my mind that if this "space" is to be as comfortable as a home environment, that some kind of insulated sub-floor system will also be required. I have worked in enough on-slab cozy offices in my time, seeing the secretaries with the electric heaters under their desks. Not to mention. That at some AGE, no temperature will be right for more than five minutes, lol

There is a lot of truth in that last sentence

I beginnin to worry bout some of you boys and lack of woman and energy management skills.

I was runnin dat job take minimum of 3 years and (removed) got bunch of new tools and saved data. Woman be on guilt trip fer workin my fingers to de bone and change over to new hobby she can accomplish in closet in house and I got bunch of extra shop time wid recliner area in clean end. Got soda chiller and microwave in der too.

Man goes at dis wrong woman gonna have him thinkin he can pick up turd by de clean end and drivin him to try.

Man who comes up wid foot heating pad wid DRO like welding machine gonna make more den Mike Lindell. DRO gotta sense square inch of pad where miniheater is using maybe 10 watts.. No reason to heat clodhopper when woman can be convinced by display her feet is warm & toasty. Good computer kid like dat Muhamed kin probably make it readout on her device wid flasher saying OVER TEMP wait for auto reset. Womens conditioned to accept readouts. Even better if phone tells her.

Got buddy swears thermostat not worth it in house occupied by woman. She come in poke it up, pees, takes coat off, pulls crap out of freezer, turns on TV and kicks back wid tea. By bottom tea cup she hot, but no way she put thermostat back right. Opens window to let heat out. Might as well just put light switch on wall and spend money on fuel.

Smart man knows how to interface wid female brain in safe way for man. Gotta be thunk ahead and have least 2 plans ready. (removed) not harem master cause he fight wid women.

With the price of insulation it has gone up 30% or more in the last year. Look for a place that cuts insulation for air conditioning systems. Hear me out there was a place in okc ok that a few years ago you could get all of the insulation you could load it was the cutouts. I got enough to insulate a 1700 sf house for gas money to go get it. You need as much as you can squeeze into it unless you want a big energy bill
