UK: Breeze block inner, cavity with rock wool and brick outer with internal walls of basically studding with plaster board for my 1985ish 'compact and bijou town house'. Some medium-rise blocks of flats use steel frame floor plates from concrete central pillars with external cladding approach but most new houses are brick.
