The top 4 things
1. What size shed am I allowed to have without Council approval? Check your local Councils planning scheme, under their outbuildings section.
2. You have the perfect location? What is the access like, a site visit maybe necessary.
3. We build sheds to buy as is, or we can be commissioned to build a shed. Do you have a design in mind?
4. What will the shed be used for? Knowing the sheds purpose will help guide us.
