Neighbor's building has a roll-up door. I like a sliding barn door, it loses the least head room. But I don't have snow to contend with. Did you consider double sliding doors? You could have almost 12' width without extending past the sidewalls.Yeah, those guys with the tall stacks need tall doorways! That's actually the same plan size as I am contemplating. The shed will be in view from the house, but downslope some, so maybe I can get away with a 16-foot sidewall. I have to get out there with some stakes and some bamboo poles and mock it up!
On the aesthetics, I can't get crosswise with SWMBO (She Who Must Be Obeyed).
Can a doorway EVER be too high or too wide?
I was thinking of putting the big sliding doorway in the center of an endwall, but on narrow buildings (less than 40 feet wide) the pitch on the roof tends to limit an endwall's doorway height and width - you don't want the tops of the doors higher than the roof line when the doors are open! And, it just looks goofy to have the outer ends of the door track hanging out there in space.
On endwalls, we would make two doors meet on the lengthwise CL of the building. Endwall door frame-out is much simpler construction than for sidewall doors. Because on the sidewall, you're limited to a 9 foot-wide door opening and height at least a foot lower than the top of the sidewall, if you don't want to use headers and a stub pole to support the truss-end that would land in the doorway. It's just $$$. To me, 9 feet is too narrow for a sliding door, especially if you're wanting to back something around a corner on the way in. So, I'm gonna put my sliding door in the sidewall. It'll be 12 feet wide, with a clearance of 11 feet of height. That's like a minimal door height, in my mind. I'm going to have to balance the aesthetics of a very tall sidewall and a low doorway in a compromise of both...
Hey, the aesthetics RULE in the downstream marketplace!
And, MUCH more importantly, to SWMBO.
