My greenhouse is a lean-to with a solid back built completely from selected pine 2x4s. The back is 16' high and the slanted part is 24'. ("standard" sized lumber). I believe the 24 footers are #1 grade. I have done nothing to it since the original construction. The only part that really needs some attention is the outside of the back which is covered with 4x8' exterior paneling.

The foundation is cinder block. The 2x4 footers fastened directly to the tops of the blocks. I've attached a picture showing the shell during a film recovering a few years ago.

The vertical wall for the first level of triangles will provide more usable interior space. The top of it will, however, be subjected to a considerable radial (outward) force transferred from the upper levels. (You just have to take this into consideration.) A tensioned steel wire connecting all the tops of the vertical level and anchored into the door frame could work. Of course the door frame would have to be strengthened or reinforced with a type of gusset. Just a thought.
