In the late 80s, by dad built a loft staircase by utilising a built-in wardrobe in the box bredroom. Just cut a hole in the ceiling and made some stairs. Pretty unique - never seen anything like it since. It looked like normal wardrobe, but contained this magic mini staircase! Obviously would be totally against modern best practice and building regulations etc.
Ah, The 80s! When we still had freedom, and self reliant people could use their ingenuity and achieve things without having to have a bit of paper approved by jobsworths. Young people are now frightened of their own shadows.
