Turning my carport a workout site

I have a carport that I am hoping to convert into a workout space… It is a metal structure with a roof and two unfinished sides.

It sits in the sand quite a distance from my house. I want to hire out all the services to make it functional. I want to pour stone to have a smooth floor. I want the walls finished and the ceiling raised, then next I am hoping to get electricity in there so I can have heating and cooling; The space won’t be too big, I feel a ductless mini split could handle everything. I would like to get a smart control unit that I can control from my cellphone. That way I could be in bed and turn on the heater or a/c. Then by the time I get to my workout space, I could have the right temperature there. It wouldn’t have to supply temperature control for long, just around an hour. I feel the cost of the ductless mini split won’t be too disappointing either. I don’t need the installation to be pretty or to have the unit hidden from prying eyes. It is just a workout facility, slap it in there, having quality heating and cooling will be a game changer too, and right now I am relying on a space heater and a box fan for temperature control. It just doesn’t get the job done, but also, my workout space is a bit narrowand short, and so having a full carport will be a huge update for me.
