I bought this shed and put it together by myself in the first week of March 2021.  The building directions were pretty good although there were a lot of parts and hardware and I had to be very careful in order to build the kit correctly.  It took me about 4-5 hours over two days to build it.  One additional helper would have been nice to have but was not necessary.  I built it on an existing concrete slab and I can move the empty shed by myself if necessary.  If you are building this by yourself, you MUST build it when the wind is not blowing to much because the walls and roof are easily dislodged by wind unless you have a helper.  Other than these comments, it seems to be a very nice shed and should last many years.
