Very sturdy and nice shed. Lot of parts and steps to follow.  Took me and friend 4 or 5 hours to put together.  We are experienced in putting stuff together and have all the tools.  You need to follow the instructions to a tee.  Most importantly base has to be perfectly square installed to the exact dimensions provided or you will run into issues later with the door not being level etc.  After you put the pegs and or some of the screws, you cant take them off to fix your mistake, so make sure you follow instructions very carefully. 

The manufacturer is very helpful with installation help or shipping missing parts if you have any.
