Hi everyone, I'm brand new to the forum and building in general. I recently moved into a new rented accommodation and we have this pretty cool roughly 14'x12' workshop at the back of the garden. It's pretty run down and very gross inside at the minute but I'd like to try and save it or rebuild if it is passed the point of saving. It does have electricity running into it in the form of a very dodgy over head cable from our carport. I'd rather not spend too much money on it though as it's just rented accommodation hence why I'd rather save than rebuild. Can anyone tell me from these pictures if I can save or not and the best way to go about saving? Sorry they aren't great photos. If it is a rebuild job, what are we thinking cost wise?
