! i love the carts under the stairs. awesome!

Wow! Who knew you could find such unique ways to hide your clutter. I am most impressed by the hidden laundry area.

#2 looks like a good place to stash the bodies

I know that if I had #1 in my kitchen, things would be flying of the shelf every time I opened the door. Love the ingenuity of these, though! #4 is great.

#4 seems not to be a straight forward slide in & out kinda thing. I bet it requires some steering -- like my portable dishwasher -- especially with the angle at the top.

I guess I'd rather save the space under the stairs for Harry Potter... ;)

Number 1 could benefit from those security rails they use for shelving on boats. It's the most entertaining of the options shown, especially since the cabinet doors on the bottom could so easily cover no more space than the open shelves, making the much deeper space a surprise.

#1 is brilliant and will solve a problem for me. Thank you.

My favorite hidden-storage trick, which I might have seen on this blog, is building drawers for shoes into the stairs by the front door. Not in the wall supporting the stairs as in #4---that under-stair space can be better employed---but in the riser space.

So great. I was planning on doing something similiar but with pegboard but these? So much better.
