A business park or office park is an area of land in which many office buildings are grouped together. The first office park opened in Mountain Brook, Alabama, in the early 1950s to avoid racial tension in city centers.
These are popular in many suburban locations, where development is cheaper because of the lower land costs and the lower building costs for building wider, not necessarily higher. Some businesses prefer the larger floorplates as more efficient, reducing time lost moving between floors. They are also often located near motorways or main roads.
