In the 1960s and 1970s, high-rise buildings consisted mainly of suburban gallery flats. High-rise buildings are now part of the cityscape and have a lot of architectural attention. In a residential function in the center of a city, these are more often luxury apartments. Officially, the building falls within high-rise if an elevator and extra escape routes must be built. That is from five floors. The different forms of high-rise can be: a free-standing tower, high apartment buildings connected, high apartment buildings with galleries. The residential towers are getting higher and the rules for construction are being adjusted, such as rules regarding fire extinguishing systems. Since 2008 there are residential towers with 30 floors. They reach up to 150m in height. If you want to find all available aerial photos about high-rise, look in zoeken beeldbank.
