Question Advice for adding new farm building?

I’d really like to add a hot-tub to my farm. Happy to do all the work – I have a coding background, though not with games. I just don’t know where to get started.

My idea: new farm building that can be bought from Robin. Same size as the coop probably (or maybe 2x pond), with mechanics similar to the spa near the rail tracks: small changing area, hot pool which replenishes energy. Maybe the music changes when in the hot-tub (more relaxing theme). Some string lights which turn on at night.

What reference material should I be looking at to start? Advice would be greatly appreciated!
