Well folks you have been asking about my shed. I just took it a few minutes ago and it WAS cold! Sorry its so dirty, it had rained and then snowed and froze everything over! If there is anything different I would do this shed, I would need a BIGGER shed like my other one the eight by ten ft shed. I was looking for the eight by eight Yardmaster but they no longer carry them anymore. My next door neighbor has one and one of these days if I can find one, I would love to have it! Cleaning this shed is wonderful and dries in a matter of a few hours. Horse rubber mat on the bottom with wood foundation and patio blocks under that foundation. Used a basement screen window for the window and homemade 2 x 2 wood and hardware wire for screen door. Dog door for the coop. The door is removed during the day for fresh air and close back up at night. If you have any questions, please feel free to ask!
