My shed makes great use of its small 6x4 ft size by being able to be opened out to produce a pizza oven/prep area but also a small bar. All with built in speakers, optics and a destinctive design.
I was limited on budget and space hence the size of the shed, the shed was bought from b and q and then converted by myself and a friend over the space of a couple of weeks. To save on money the vast majority of materials used were old pallets. The big advantage of the shed is it's ability to be packed away when not in use and not take up very much space at all. I have not got a video on YouTube but would really recommend seeing some picture of the shed as it's very difficult to do it justice in words.
