Amsterdam Nieuw-West is one of Amsterdam's largest city boroughs, consisting of the former city boroughs Geuzenveld-Slotermeer, Slotervaart, Osdorp and parts of Westpoort and Bos en Lommer.
The "Nieuw" (New) in Nieuw-West is due to it's location west of the former most western city borough of Amsterdam: Amsterdam-West, which was mainly built in the years directly preceding the second world war. Nieuw-West's residential areas were built in the first decades after World War II, while Amsterdam was recovering.
In Nieuw-West a new philosophy in city planning was applied at a larger scale for the first time. Nieuw-West's architecture is notable for its open and spacious style of building, with large areas of green surrounding the buildings.
This new style of building was propagated mainly by the initiatives of architects Cornelis van Eesteren en Jakoba Mulder, who were responsible for most of the early post-war city planning in these new residential areas.
Central to Nieuw-West is the Sloterplas, a large lake that was dug out for the sand needed to raise and solidify the surrounding residential neighbourhoods. The Sloterplas and surrounding areas now form a large recreational city park.
Since 2001 several post war neighbourhoods in Nieuw-West have been replaced by new housing in the context of a large renovation project.
