Mile-high Tokyo tower could dwarf world's tallest building

Tokyo’s skyline could reach to a mile high if futuristic plans for its Sky Mile Tower in the city’s bay get the go-ahead from regulators.

The proposed building of the 5,577 foot-high edifice is designed to reach twice the height of the Burj Khalifa in Dubai, currently the world’s tallest building at 2,716.5 feet or half a mile.  The tower complex would dwarf Tokyo’s current skyline and become a mini-city adapted to fight climate change. The hexagonal design of the tower –  best for wind-resistance – has half a dozen building legs interconnected to a form a tapered structure. The Daily Telegraph reports that at intervals of every 320 metres, there are multi-level sky decks together with public facilities such as restaurants, hotels, shops, gyms and libraries.

The development could be home to 55,000 residents with lifts running between the five residential zones. The complex has been designed to be eco-friendly as it would transfer waste heat from one side of the edifice to the other, thus ensuring energy efficiency. Water also would be centrally collected and stored with distribution using gravity to eliminate normal pumping costs.

Surrounded by an archipelago of islands, the Sky Mile Tower would be a high-density eco area as it becomes central to the ‘next Tokyo.’ If approved, the project would take close to three decades to complete and would look down on the 3,280 Jeddah Tower in Saudi Arabia which is due to be finished in four years time.

Architects at Kohn Pedersen Fox and structural engineering firm Leslie E. Robertson Associates, both in New York, are key players in the proposed construction in Japan. Conceived as an effort by the Asian city to protect itself from the problem of rising tides, the new complex would include a series of specially shaped islands that would act as a barrier to flooding. The development also includes plans for farms with the potential to harvest algae that could be turned into fuel.
