The ‘Casa do Povo’ cultural centre in São Paulo, an icon of the secular Jewish workers’ movement: a crumbling theatre flanked by staircases, entryways and corridors. Construction noise drones away in the background, clinking crockery, a broom sweeping over tiled floors, an expressive façade of countless adjustable panes of glass covered by a patina. It’s October 2016 and a group of young people are preparing a preview of Bickels [Socialism]. The venue is to form a prologue to the completed film, which tours 22 buildings in Israel designed by Samuel Bickels, most of which for kibbutzim. Dining halls, children’s houses, agricultural buildings, bright structures inserted into the Mediterranean landscape with great ingenuity. An architecture with a sell-by date: That many are now empty or have been repurposed at best is linked to the decline of the socialist ideals they embody.

The final part of Heinz Emigholz’s "Streetscapes" series is again a triptych. A prologue examines three buildings from the 1930s designed by Julio Vilamajó in Montevideo which could have inspired the work of Eladio Dieste, the subject of the main part of the film. The industrial and functional buildings presented span the period from 1955 to 1994; their organic brick construction is astonishing and inspiring.

A film director confides in his interlocutor. He talks about the working process, about creative blocks, about artistic crises and expressive forces. At some point, the idea takes hold that this conversation could be turned into a film. And this is the very film we’re watching the two of them in.
