In Central FL, I'm looking at butting a bigger shop in. I've done quote a bit of pricing and am looking at about 25k for a 20x30. That's slab poured, steel building delivered and set up, and buying everything I need for insulation, HVAC, and electrical on the inside, but planning on putting all that in myself. That price does include a garage door and opener, but there's a lot of electrical supplies. I want a 50A sub panel, and a bunch of power drops. HVAC was just a basic split unit, pretty cheap and also installed myself.
