The â€˜Casa do Povoâ€™ cultural centre in SÃ£o Paulo, an icon of the secular Jewish workersâ€™ 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 faÃ§ade of countless adjustable panes of glass covered by a patina. Itâ€™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, childrenâ€™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.
