I have a unique garage/shop setup especially for a house in the Bay Area. It's always been difficult to explain, I've always said that you need to just come over and see it to understand. I'll do my best to explain the layout and put up a bunch of pictures on here. My wife and I moved into this house towards the end of 2023, so I'm still reworking and adding things.
The house is on a hill so the garage and the shop/basement is below the living area. The garage is a small 2 car 16'W / 22.5' L / 8'H. Next to the garage through the double doors is the shop that is 8.5'W at the narrowest, then widens out to 13' and is 38'L. The shop is pretty cool, the old man that lived here before me built a L shape work bench with a ton of drawers and overhead cabinets. There are a lot of cool little things that man did, like different exhaust fans that vented outside, pulley systems to lift whatever he may have built, custom storage shelves, and a hidden "safe". When I moved in, I did a lot of clean up, the shop seemed to be neglected for many years. From what I heard from the neighbors is that the old man was in his 90s and couldn't make it down the stairs to the garage/shop for a long time. Me being an electrician, I rewired everything, added new receptacles all over, rebuilt the exhaust fans, and put in new low profile LED lights. The shop even has a half bath which is a nice touch.
The second area that comes off the shop, drops down even lower. We use it as a home gym and extra storage space. It has 16' ceilings. You access that space from a built in ladder in the shop, which I think the old man built, or the door to the back yard.
That's a basic run down, check out the pictures to get a better idea, but like I said you really have to see it in person to understand it. Some of the photos are rotated and idk how to fix it so just turn ya head haha.
