Answer 2

For something that size, you generally frame each
wall flat and then elevate and join them.
Are you asking about roof trusses here?
For a storage shed, 2 x 4 studs will serve for the
walls, but you'll need something heavier for the
roof depending on slope & span, (Snowload etc.
varies with location.)
