There are lots of £3,250,000 mansions around London's Crystal Palace, but there aren't many whose attics have been converted to spaceship control rooms. The estate-agent-ese in the posting is enough to melt your eyeballs, but I gather that this place is has 8 bedrooms, is about 7,000sqft, and is both Gothic Grade II and Victorian Grade II listed (or possibly these are interchangeable).
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.
