Call it speculative architecture. Nakheel Tower in Dubai would be 1400 meters tall, much taller than the Burj Dubai, which at 828 meters is currently the world's tallest building. Will it ever be built?
Architecture firm Woods Bagot designed the Nakheel to stand out of the landscape, but blend into local culture. According to Inhabitat:
To achieve a height of over 1,400 meters, the tower features an Islamic building typology that divides the Tower into four cores, with slots in the middle up near the top. These slots allow wind to pass through the building, reducing the wind load and allowing for uniformly-sized floor plates to be used the whole way up. The vertical city will be a LEED certified eco-tower and include black water treatment, storm water harvesting, reuse of fire test water, solar panels, wind turbines, and high-voltage power distribution.
If this building were planned for anywhere else in the world, I'd call it science fiction. In Dubai? It just might happen.
