My present shop was finished while we were enjoying the nationals in Detroit (2007). It is very nice, BUT I use the heck out of it, so it is very hard to clean. Dust, and overspray from cleaning and painting parts has taken over surfaces, and oil etc has taken over the work areas. I use a lot of cardboard on my bench areas (over 30 ft working surfaces), but floors are hard to clean because I had an aggressive surface put down to help avoid slips and falls.
  I have a separate room for parts washer, sandblast cabinet, and other cleaning stuff, a decent bathroom, with laundry sink for parts washing/rinsing. The shop is mostly used for my personal projects.
  Upstairs is my "library/computer hamshack" very messed up with many ongoing projects and a Ham club repeater. I have many (but not enough) antennas on the outside in back.
  Half of the building is insulated and heated, with the front part (up and down) considered "cold storage". 3 vehicles stay out there, along with surplus cabinets for chemicals, oil , paints, etc and shelves for parts semi organized. The shop holds 2 vehicles, but it is more comfortable with one.
  I think there have been other pictures posted on the CNYCC website of the building. It is 30 X 44 steel pole barn type construction, with decent insulation on the back half, and an 80K BTU hanging propane furnace for heat. It is not that bad to keep it very comfortable. I spend most of my life out here playing Corvairs and ham radio.
  It is well equipped with tools for what I need to do. It has full wiring with 100amp service, internet, security, phone, cable TV, over 200 ft of copper air supply in the walls, 100 gallon reserve air tank, ceiling fans up and down, etc. My air compressor is back in the house garage on it's own power sub circuit, and is fed underground in copper inside black plastic, beside water fed with pextubing inside black plastic @ 30 inches underground (local codes) along with another 2 inch plastic for other wires. I spent extra time allowing for extra needs for power and grounding for the upstairs ham radio equipment. I have a wall of bookshelves for ham radio magazines, and corvair research materials. The rest are in a room down cellar in the house.
  It was built on a budget fed mainly by the selling of our boat, which we gave up because of changes in our health and moving into a one floor home. It could have been built even cheaper if I had done more shopping for contractors, but I have known this builder a long time, and work well with him. The shop is not detailed, but VERY functional.

Current vehicles:
63 rampside since @ 1985
61 Lakewwod  unfinished
64 Monza  factory A/C  unfinished
61 ??? Crampside  VERY unfinished  (another looong story)

parts cleaning room has tumbler , ultrasonic cleaner , various nasty cleaners and solvents , old ( I bought it new in 1974 ) TIP sandblast cabinet , and finally a new real parts washer.I added a nice plywood top to it coated with water based varnish , which so far , holds up to about any chemical I put to it.

There is a bathroom downstairs , with a laundry sink used for parts rinse.(in the far corner)

A lot of the cabinets and counters are garage sale finds or varnished cheap grade plywood

There is always a lot of dust / dirt from parts cleaning with high speed wire wheels and sand blasting. Also I do a lot of painting of sheet metal etc with semi gloss black. Results are good clean parts and a dirty shop that is very hard to clean.

the alley between the shop and garage fits a car trailer , which works well for parting out vehicles. I sometimes park cars out there in good weather for work.

The upstairs has a recliner to rest in , when reading. Also has small refridge and microwave. I spend time up there on ham radio.

It is a busy spot both with Corvairs and Ham radio.
