Killarney Hills, designed by Monty Sack, is an outstanding example of late 1950s Brazillian modernism. Commissioned by John Schlesinger, who inherited his father Isidore Schlesinger’s business empire, the building included penthouses designed for John and his brother Julian. The works of several prominent artists enhance the design: desiccative off-shutter concrete panels by Edoardo Villa, a mosaic by Armando Baldinelli, light boxes and door handles by Giuseppe Cattaneo, a painting on glass by Larry Scully, painted and graffito murals by Monty Sack himself.
