[Oh, I forgot, I also made two "freestanding sheds" that are technically portable but very heavy. One for the trash can and one for the freezers. I guess that means we have built 9 sheds plus the horse shed plus the shed we bought equals 11 sheds on the property. I have tried to do a very tasteful job of placement.]
We bought the cute little barn style shed when we first moved in here and all our stuff was laying in the dirt while we were getting the garage built. The garage didn't take long to build but we had to wait three or four months for the contractor to have the time in his schedule to build the garage.
I am basically in charge of getting the last several sheds done. The greenhouse, Hubby helped me get it started and he helped frame for the windows. It definitely was a two person job getting the windows in but I did all the rest of the framing and the walls, the trim work and painting. I put a ventilator turbine in the roof and a small ventilation window in the far side. I hung a wooden door and re-used our broken screen door on the east side. I am pretty proud of the greenhouse. Sturdy and very usable. The long shed, Hubby did the posts and then I was on my own. On the shade cover, I actually did most of the posts myself. Okay, there was a little boo boo on placement of one of the posts but you can't really tell unless I point it out and I don't!
I built the trash can shed and the freezer shed all by myself:) They aren't perfect but they have held up for a number of years and through several ninety MPH wind storms. Not to mention the one year where we had two feet of heavy snow. Didn't break my roofs!
