My husband helped me to put it together, maybe about an hour or so. We did take the advice to put a concrete block on each corner on the inside and we also tied it in the back to our fence. We got some pavers to put around the entire perimeter for added stability. It has worked great so far! We have had a very windy March and it is staying in place! It is 43 degrees outside today and very windy, but a cozy almost 80 degrees in the greenhouse! At night we have had below freezing, so I have a little space heater for those few nights that it was so cold! I have spaghetti squash, zucchini, lettuce and snow peas growing. I actually put some netting in the greenhouse for the snow peas, because it is too early to plant the outside.
