Framing long shed wall on small area

[naf305]

So I'm building a lean-to shed (see link in signature) and I'm now planning the wall framing part of the project.

My question is how to frame the long walls parallel to the garage. Those are 20ft long and will be 8-9ft tall.

I only have a 20ft x 5ft level floor to work on. Right now I can't plan on using the shed floor at a flat work area to frame the wall and raise it up.

How would go about doing this? Built-it in place (if so some details on how-to would be much appreciated)? Create a temporary flat surface using plywood sheets to have a 20ft x 10ft area to frame the wall on then raise it up?

Here is a pic of the area I'm working with:

Break up your wall into 3 panels.
Frame one at a time, carry them out and learn on the wall.
When you have all three invite some friends over to place them.
The extra studs will be money well spent.

Interesting idea. I can picture that working. Should I frame with a single top plate, raise the 3 panel and then put in a crown plate that will overlap each panel and join them together at the top (on top of all the nails sistering the panels together)?

I would build 2 sections of 10'. If working by yourself, stand the first one and nail it down and also have a temp brace either going to the back of the garage or floor. Then stand and nail the second section together and to the floor. Again brace that section and join them with the second top plate and where they meet.

Yes.
Frame with a single top 2x4 and tie them together when installed.
If you only skin the lower half while down you can then tie them together with the upper half sheeting.
It may be easier to build them on top of each other to avoid have to manhandle them out one at a time by yourself.
