Le Corbusier wasn’t a communist. Villa Savoye is a bourgeois paradise.
The diffused aesthetic of blank surfaces and horizontal windows was a nod to his socialism. He was all about reorienting civilization into one international egalitarian culture. All the modernists, the true theoretical modernists, were commies. Central planning, social engineering, Utopia.
If you’re interested in this subject, Jane Jacobs is still the best source and The Death and Life of Great American Cities shows (almost explicitly) how socialists have destroyed our cities. “Organized Complexity” is the same as Hayek’s “Spontaneous Order.” In Jacobs’ Economy of Cities, she shows how advances in society have resulted from people coming together in cities. The way that Cape Town was planned, it was going to fail without top-down enforcement from its social engineers.
