Bianca Gleissinger's humorous debut documentary 27 Storeys is about Austria's largest social housing complex, Alterlaa, and its former promise of happiness to its residents. The director returns to the place of her childhood and meets its quirky and amiable residents - at the shooting range, at the rooftop-pool or on the balcony - and thus provides a deep insight into a social biotope. "Upper class living on a working class wage." was the utopian premise of architect Harry Glück in the 1970s. This film is a witty, very personal approach to an obscure place and an examination of the director's own roots.
