I didn't build this, it was there when we bought the place in April.
It's a 34x28.
We've talked about building a *shop* in the future, but how far out that is, I don't know.. so I'm prepping the 3-car garage and planning to be there a while..
One single 9x9 (I think) door on one end, and a double (8x16?) door on the other, with the man-door and house on the "double door" side.
The bay closest to the house will be my wife's parking spot. Bay next to it (accessed via the double door) will probably be parking for my driver, though I'm far more flexible about parking outside for more shop space than she is.
The single door, that's 9' high.. that's the work bay.
Most of my rigs will *just* fit through a 7' door.. the 8' door leaves 'em with room, and then the 9' door should clear most anything I care to build at this point.
Bonus to the double-wide door.
When I pull my crewcab long-box in for the 4x4 conversion and/or paint, I plan on pulling it in via the double door and pointing it at the corner of the shop, at the "far" end of the work stall.
Thus I'll take up both the work-bay and my parking bay.
But with a 21' truck, it might not work too well to just pull straight in.
I think angling the truck through a single door would be a chore, but going through the double will be easy.
As the others said, make sure you have enough space between doors to do something useful. 3' or so is a good width.
One of my complaints about this shop is the wall is kinda "narrow" on the work-bay.
Less than 2' between the edge of the single door and the wall. Not enough to do much with. If I lined it with shop equipment I'd have to angle in through the work bay door just to walk down the side of my rig.
So instead that wall is slated for "rollcage tubing storage".. otherwise, it'll be clear, so I can walk down the side of my rig.
BTW, the double-door is the only one with an opener on it.. and I think I'll just leave it that way.
Get two remotes and we can both open the door w/o getting in/out of our rig..
I don't mind having to manually open and close the work bay. It's not like I plan on driving in and out of it every day.
If I'm not actively wrenching, I'll probably park one of the trail rigs in.. in which case, it'll only leave on the weekends anyhow..
