Nah, no designs on blue prints on it. I had actually come onto this site and seen a style similar to what I had built and just winged it. Anything is possible! Just make sure you re-enforce support for the roof and get your studs every 16" on center. Have fun with it! I went with OSB on walls and ceiling because my hubby told me to make sure my walls are solid with 3/4" plywood. Well, if anyone has checked out the price of that stuff lately, it isn't cheap. It was actually cheaper to buy OSB and a thinner exterior plywood to obtain the 3/4" thickness than it was to buy one 3/4" exterior plywood. So, obviously I went that route. LOL. It was a blast building it and figuring things out on my own. I'm a girl that likes to work with her hands though and when I get it in my head to do something, I do it.
