Via ibīdem, we are directed to the ensemble housing estate of Ivry ˢ/ Seine, a Parisian suburb just southeast of the capital, designed by architects Renée Gailhoustet and Jean Renaudie constructed between 1969 and 1975, happily still standing though in need of some care and attention.
The name of the mixed-used complex with forty residential units for social housing with commercial and office spaces refers the stellar rays of the triangular points of exposed concrete and whilst the overall style could be described as Brutalist (see also here and here), the open form structure with staggered verdant terraces and ramps and platforms connecting public and private spaces has an element of social engagement and spontaneity of interaction not found in all projects of the genre.
