Here's an interesting idea for those looking to have multiple levels in a smaller space: a "monk" staircase. The steps alternate from left to right to allow the stairs to be a much steeper grade, making them function more like a ladder and saving a lot of space. I'm not sure how much I like this idea for a home with kids, but it would work well in a loft-style home for young urban hipsters. The monk staircase in this photo is found in a dome-style home in Ann Arbor, Mich. Note the rounded ceiling in the photo. Very cool.
