Fifth and Columbia Tower is a 660ft (201m) tall skyscraper approved for construction in Seattle, Washington. It will be completed in 2014 and have 43 floors. It was designed by Zimmer Gunsul Frasca and is being developed by Daniels Development Company. When the building is completed it will be the fifth tallest building in Seattle, and the tallest building completed since 1990. To achieve LEED Gold standards it will have a system to capture rainwater for reuse, a 35-foot-tall (11 m) "living wall" where plants grown in Columbia Street facade, and a rooftop solar energy equipment.
