Hello,
We are sorry to see that you are not satisfied with your shed. Assembly time depends on a variety of factors, including roof design, tools available, DIY skill and the pace at which you work. Guidelines for each shed assembly are approximate AFTER completion of the base, and assume two or more people working on the assembly. Generally, you should plan on at least one day working with someone who can assist you; again, after constructing the base. Once fully assembled and anchored most customer do get 15 years+ out of their sheds. Thank you for taking the time to share your thoughts and we hope you are enjoying your assembled shed!
