BARBER Le Corbusier’s “vernacular turn” in the formative years—from the influence of the 1930s has been a point of much discussion for regionalist painter Charles L’Eplattenier, architectural historians. Why the shift away through his 1911 travels in the Balkans and from purism? Concerns about the climatic direct experience of a “pre-modern” culture, to performance of a building, it turns out, were his engagement with the German Werkbund paramount—not only to Le Corbusier’s shift, in the late teens and twenties—Passanti writes: but also to the direction modern architecture would take in subsequent decades.
