Wendy house - dismantled (Coney Hall BR4)

I have a Wendy house for kids which I have just taken apart so it can be collected. The roof could do with replacing as it is a bit rotted. Needs a bit of TLC but still perfectly usable. The first photo is from a while back. The current roof has no felt on it. There is spilt paint on the flooring inside, but could be cleaned up and improved
