Inside the world’s most expensive apartments

While housing prices in Canada may be getting less affordable, they still pale in comparison with those in cities such as New York, Tokyo and London.

Take the world's most expensive apartments: One Hyde Park in London, England.

The least expensive apartment sells for slightly more than $10 million while the priciest goes for about $220 million. The average cost per square foot? Roughly $9,500.

The four buildings with their 86 apartments were officially opened to the public last week. According to the developers, the Candy brothers, 60 per cent of the apartments have already been sold.

However, the Daily Mail reported only two of the sales have actually been completed, both to investors in the project, while deposits have been made on a further 26.

Whoever ends up living there will do so in the height of luxury. The buildings feature a private cinema, 21-metre swimming pool, golf simulator, wine cellar, panic rooms and even a tunnel to the exclusive Mandarin Oriental hotel nearby.

The builders used 15 different types of stone in the construction, including nearly $80 million worth of a special "sparkly" concrete.

The buildings were designed by Richard Rogers of architecture firm Rogers Stirk Harbour + Partners. Rogers is best known for designing the controversial Pompidou Centre in Paris, The Lloyd's building in London and the much-maligned Millenium Dome, also in London.

Rogers' inside-out style, featuring heating ducts and elevators prominently displayed, is set to come to Canada.
