An interactive map shows Los Angeles buildings by construction decade
The visualisation represents buildings across the City of Los Angeles as coloured boxes, spanning construction dates from 1880 to 2026.
An interactive visualisation offers a building-by-building view of Los Angeles, representing each structure in the City of Los Angeles as an individual box.
The boxes are coloured according to the decade in which each building was constructed, creating a visual record of the city’s development from 1880 through 2026.
The project is hosted at lax-skyline.parcelscope.net and was shared via Hacker News on 7 September 2026. Its original headline described the experience as watching Los Angeles get built “one building at a time”.
The available material does not explain how buildings were identified or dated, or how the visualisation’s geographic boundaries were defined. It also does not clarify whether 2026 refers to completed buildings, projected construction or the latest year in the underlying dataset.
The visualisation presents its coverage as every building in the city, but that claim has not been independently verified. The source provides no building counts or separate analysis of development patterns.
