After seeing so many impressive garages here, I'm curious what upgrade made the biggest day-to-day difference for you. Lighting? Insulation? Air lines? Better storage? Looking back, what was worth every penny?
Going along with your questions, then expanding:
1. Lighting was planned from the start. What was to be installed was not determined until the hospital where I was working was upgrading lights. I got 16 double-tube fluorescent troffers that I recessed into the ceiling. Recently re-wired for LED tubes.
2. Electrical planning included receptacles in quads, around the room (24x30) and powered by at least six circuits on the lower level. 240v receptacles are included inside and out (so my son can plug in his RV).
3. Insulation was also planned from the start. Only have 2x4 studs, so limited to R-13. I have attic trusses, so upstairs is also insulated, giving a bit more moderation for the lower level.
4. Air lines also planned from the start. Compressor lives in the closet under the stairs, 1/2" copper line comes out near the ceiling, then splits to front and rear runs. Two drops on each leg, each drop has its own drip leg.
5. HVAC was planned from the start, but did not happen until 10 years after construction. Pre-ran wiring to where I thought the outside unit would be. Things changed a bit, had to extend the wiring across the back of the shop to the new location. The 24k mini replaces a 50k K-1 torpedo in winter and a bunch of fans in the summer. THAT was worth waiting for.
6. Bathroom was also planned from the start. Just a toilet and sink, but that's enough. A small on-demand water heater hangs on the wall over the toilet, it serves the bathroom sink and the shop sink that is on the other side of the wall.
Other improvements along the way include a bike lift that is capable of handling my wife's CanAm Spyder. Most of the storage consists of shelving that was salvaged from the hospital just before it was pushed into the dumpster, so it was all free. Might not be exactly what was planned, but the price made it worthwhile.
