I made it from used hardwood railway sleepers and used scaffold boards. we use it for entertainment and you can sleep in it if you want to.
I decided to make this shed from some old reclaimed railway sleepers that a came across. I ended up having to spend quite a lot of money to build it but felt it was worth it. I made the entire cabin all on my own and used my abseiling equipment to lift the heavy sleepers into place when it got quite high.
