In Vienna, Austria, architects are planning to build the world's first wooden skyscraper. At 24 stories, it will be the world's tallest wooden building, and house a hotel, apartments, offices and a restaurant. About 75% of the tower is expected to be made from wood and architects say it's construction will save about 28 hundred tons of CO2 emissions when compared with similar concrete structures. It makes sense: wood has been a sustainable building material for hundreds, if not thousands, of years. While it is unlikely that we'll start to see wooden skyscrapers popping up all over the globe, the fact that this design is turning heads in the world of architecture, shows once again, that embracing current cultural trends in a creative new ways is a great way to attract attention. Expect to see many more architects embracing the green trend and doing something radical with it.
