Architects Specht Harpman converted a 425sqft Manhattan micro-apartment into an amazing, multi-tiered living space by building up into the apartment's 25' (!) ceilings. It's got a bit of that shipbuilder's vibe, with cabinets built into everything, including the staircases. I love the tiny swatch of grass, too. I live in a very small place, and looking at this makes me want to explore how to cram more into our little place -- we get about 650 sqft of livable space out of an 18' square/22' tall place that's laid out in two storeys. Using this kind of technique, it seems like we should be able to get a much more livable and spacious place.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
