This is my structure. I imagined it as a large office block for some kind of broadcasting company. It has a large eating/ sitting area on top- Broadcasters are notorious break milkers! The challenge with this was working out the scale, I had to redraw the stairs a few times as I realised to climb them you would have to be pretty much the same size as the building. I left the windows purposefully large- perfect for looking out by the watermachine thinking about network figures.
