Omer Ureta, a professional urban designer, has created this extensive and spectacular interactive map of building age in the city of Los Angeles. This map will be of interest to anyone familiar with the most populated city on the west coast as well as anyone with an interest in the history of U.S. architecture. On this map, each building is color-coded to denote the decade in which it was built. Visitors can explore the map - which includes all of Los Angeles County - by zooming in on neighborhoods of interest. Users can then hover their cursors over a specific location to view the building's address and date of construction. In addition, visitors can manipulate a color-coded timeline on this website to view building construction by decade or click on a colored clock to watch an animation of building construction over time.
