Hey Hoss
Youys works out to 9x13metres in my language.
Mine is 7x18m which is 23x60 in your language.
It is so long beacuse the last 2 bays (7x6metres) is my office.
Yep the 2 doors are for my truck, boat and camper trailer, and the tractor fits in the side door.
Minimum shed width is 6m = 20' but mine is 7m wide to allow just that little bit of space either side of the vehicles etc. Yours at 9m wide would be good. Allows for work benches and lots of storage along the sides.
I have 4 vehicle bays but only use 3, so the workbench and tractor and implements etc. use the 4th bay.
With trailers, space also isn't so critical as you aren't opening the doors etc. all the time.
My side door faces the house and is on the eastern side, so in the hot afternoons I can drag stuff out there and tinker. Also have a power point on the outside.
Now if only I could get more time to play in the shed instead of working in it.
Have fun with your plans - Keep us posted with pics etc.
Cheers
