Sick of living on boring old dry land? Then our friends at Time Out Dubai have found the home for you: a submarine apartment. A 'Floating Seahorse' - of which there are 42 available, price on application - features an underwater master bedroom and bathroom, open-plan living space on sea level, and a top deck. (The developer, helpfully, describes it as 'essentially a boat'.) Just imagine you in this, bobbing around in the Thames just by Rotherhithe! Up yours, canalboats, we've got a submarine! Admittedly, you probably won't spot any exotic fish, but if the visibility's good you might see a discarded Oyster Card! Or a stray severed human limb! Okay so it will be a little gross and impractical, but we reckon loads of Londoners would still be on board.
If that doesn't float your boat, take a look at Melbourne's chocolate brewhouse.
