LOVE this! Use a 15 dollar walmart bookshelf in closet for extra shoe or toy storage in your kids rooms. Get plastic totes from the dollar store and fill them with small toys like race cars, blocks, or crayons! Organization for cheap.
DIY: "The best loft-ladder type that I've built was using two 2x8 stringers & premade 5/4x14 bullnosed stair treads you can get at Lowe's/HomeDepot. I then used Kreg pocket-screws to fasten it all together. I'd say I have about $65 in material & 1.5 hrs labor."
