After reviewing sheds extensively on the internet, I settled on a Lifetime 6001 with a 30" extension kit w/window. The shed has 2- double doors with 3 windows, one with an operable pane. I read several reviews on the installation along with videos from the manufacturer and decided to install the shed by my self. Contrary to some of the reviews, the instructions were spot on and very explanatory. It took me a total of 15 hours to complete. The shed looks great and I am impressed with the engineering and quality of the product. This shed definitely gets my recommendation.
