Victorian mansion for sale with spaceship attic

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).
