Company is excellent when it cam% just pictures that make it extremely difficult to build; does the part go on top, in, under, etc... It can be very difficult from just a picture. In several cases we ran into this issue and had to disassemble and backtrack.  Now that it's built (still missing one part I need to order), it looks good.  The roof window does not tighten tight and, even mounted to 2x8's, while the house may not blow away in a storm, the side and roof panels will NOT last. Today, we finished the greenhouse and had 10-15 mph winds and the sides shoock back and forth bad.  Have decided to get a tarp and cinder blocks to cover and hold over during anything more than 20-25 mph. We'll see over the next few months how it is in the "growing plants" area.  Thank you.
