When I was turning my shed into a man cave, I installed a mezzanine floor as the ceiling apex is about 3.5 metres.
However, it's always been a mission to get up there. So this is my latest DIY creation:
I built a short ladder that's hinged against the mezzanine floor and held up with a hook on the right side.
My ladder in its down position. I made it so it's just long enough to swing down and connect with my work bench:
View from the top of the ladder onto the mezzanine floor:
I made the ladder sides out of a rimu door frame I scored. I'm lucky to live quite near to a business which makes aluminum windows and doors. They chuck out a hell of a lot of old wooden doors and windows that are free for the taking. I've gotten all sorts of old fashioned window catches, hinges, etc.
