Try to build a 24' x 36' x 9' clearspan shop. If there's one thing I know, always build the next size bigger than you think you need. Do your best to make it happen, you can thank me in a few years. I went from working in the dirt out of a yard shed to a 20' x 20' uninsulated garage with one 20amp circuit. Better than the dirt. Then I built a 24' x 36' pole building with 9' clearspan and and 16' x 9' roll up door on the gable end. We insulated and installed a wood stove for heat. We also installed a 200amp service with outlets every 4' down both walls and across the back with no more than 4 outlets on each circuit. We even wired it so the first light switch turned on three 4' dual tube fixtures down each side and the stereo.
Plus we got a 15" x 3 1/2" x 24' beam for free to support an 8' loft with 2'x6' floor joists, 3/4" T&G subflooring and no posts across the rear gable end of the building. I had a few thousand pounds of parts stored up there.
It was hog heaven until my wife found our current house with a 30' x 48' stick framed shop with 12' 6" ceilings and electric forced air heat. Well at least the furnace was there, there was no plenum or distribution ducts. The power wire came out of a hole in the side of the furnace with no cable clamp and disappeared under the cover panel of the 200amp service panel that we replaced because it was partially melted down from someone growing weed in there and overloading circuits.
Barnacle Bill and I built the rest of the heating system from the plenum up after we built utility and storage rooms at the back of the bay with the 8' roll up door. Now I'm really in Hog Heaven. I have the thermostat set at 69°F all winter long.
I'm guessing that you don't want to move again since you just got a great property. I know that you are like me with several projects going at once plus some work on other people's stuff. Will you be putting 2 roll up doors on the long side or a 16' door on the gable end? With the 16' door on the gable end you can add lean to roofs down both sides for project and equipment storage and a inside loft at the back for storage with a work space under it.
I've learned all this after setting up 3 shops with the help of my buddy. We use old kitchen cabinets and solid core doors for bench tops. I'm currently converting the two rows of five 8' dual tube flouresant fixtures to direct wire LED's. We have one row of five fixtures done so far and the change is huge. Lighting is really important to doing good work.
