Core idea

Functionalist expansions with green wedges

Why it matters

Classic CIAM-inspired comprehensive plan

Description

Cornelis van Eesteren's 1935 General Extension Plan (AUP) for Amsterdam was a landmark of functionalist planning: growth projected with data and zoned into separated functions, with repetitive open housing blocks set in green space, organized around a regional structure of parks and waterways.

Significance

The AUP is a benchmark of rational, functionalist, evidence-based planning — CIAM principles applied with unusual subtlety. It guided Amsterdam's growth for decades and influenced postwar planning across Europe.

What became of it

Largely realised over decades: adopted 1935, given force of law by Royal Decree in 1939, it guided Amsterdam's functionalist western and southern expansions (e.g. Westelijke Tuinsteden, Amsterdamse Bos) into the post-war era.

Critique

The repetitive strip-block garden suburbs have been criticised as monotonous and socially isolating, prompting later renewal of the western garden cities.
