I have 2 meters.
A spin dryer [it still works, I keep it in case washing machine breaks down.]
A foot spa.
A cat box.
Bags of old shoes.
Hoover.
Creepy crawlies.
And loads of crap. [cant remember what's at the very back]
I live in a flat - ground floor conversion.
Under the stairs are:
fridge freezer
step-ladder
extending window washer/cobweb brush
boxes of photographs
2 hockey sticks/2 tennis rackets/ 2 lacrosse sticks,1 skull cap & 1 bridle (not used for years).
Lots of junk
Spiders and cobwebs.
I usually clean it out once a year but since illness this has not been done. Daughter no 1 has stuff all over the house and has been asked to clean out under the stairs this weekend to make room for it. I wish I could count on that!
The main stairs lead to the cellars so nothing, the back stairs have the hoover and cleaning equipment in them and the stairs in the boot room have fishing rods, odd bits of riding tack and general crap.
