Buildings that make up most of Austin's skyline are modest in height and somewhat spread out. The latter characteristic is partly due to a restriction that preserves the view of the Texas State Capitol building from various locations around Austin (known as the Capitol View Corridor). However, many new highrise towers have been constructed and the downtown area is looking more modern and dense. The city's tallest building, The Austonian, was topped out on September 17, 2009. Austin is currently undergoing a skyscraper boom, which includes recent construction on the now complete 360 Condominiums at 563 feet (172 m), Spring (condominiums), the Austonian at 683 feet (208 m), and several others that are mainly for residential use. By 2015, the Frost Bank Tower could be the only skyscraper built before 2005 to remain in the ten tallest buildings in the city.
