Hi, I need to re do the shed sort of lucky as its only got one wooden side the others being either my home, next doors home or my garage. I would like to make the 6ft high and 7ft long wall part strong. will be making the door with my dad as he brilliant at that sort of thing and that will out last me! will be made with the materials used for wall. I was looking as OSB with new supports like 2x4 every ft along. Other ideas are 1x5 all up the front and again 2x4 supports or use shiplap again 2x4 supports keeping the uprights in place and only taking one out as the time would that be ok? Thank you for your help
