This stunningly expensive apartment shows how reasonably priced properties in Singapore are. Welcome to London's Knightsbridge neighbourhood, where this 77sq ft former storage room (or roughly 1/15 of my 3 room flat) goes on sale for the equivalent of over S$510000! Yes, this mousehole which is narrow enough to have a person stretch his arms to his sides and touch the walls was sold for over half a million bucks.

Why so expensive? Because the apartment (or space, or hole) is within walking distance of Harrods and Hyde Park. So the psf price of S$6700 of this space without electricity is good value compared to recent sales in the area which hit $9000 psf. That's 10 times the price of a luxurious district 10,11 condominium in Singapore! And yes, London is home to the most expensive properties in the world.
