If you have fallen a little short of the $50 million price tag for a Poseidon 180, fret not, the Jelly-fish 45 Habitat will set you back only a mere $2.5 million. Bargain! Designed by Giancarlo Zema, the "floating dwelling" comprises five separate levels all connected by a snazzy spiral staircase.
The floors are split into cheesy zone-titled areas including study, night, day, guest and viewing quarters. Though, if you purchase the floating mansion, you may abide by whichever nomenclature you wish. The viewpoint stretches 3m below the surface and looks jellyfish-like fantastic. The colossal seat-in-the-sea stands 10m high and 15m wide. Now, if I manage to roll out one hundred posts in 24 hours, Blam promises me a tour of his Jelly-fish 45 Habitat—game on!
