Love this little greenhouse! Don't let the size fool you - a footprint of 6x4 - because you also have a lot of vertical space to grow.  Assembly took 2'full days & 2'people.  We did have a few redo moments - but mostly because we got ahead of the directions. Although you will assemble by pictures only - 52 pages, they are clear and fairly simple to follow.  I would recommend having a solid level surface to build on, and making sure you are plumb &'level as you build to give the most sturdy foundation.  I can't wait to finish the decking & insulate the floor so I can get my plants started!
