The design features of the International Style, which became fashionable in Jerusalem like elsewhere in the world during the 1950s and 1960s, were based on purist compositions and rectangular cubic geometric shapes with no ornamental motifs. The five most significant design characteristics of this style were façades with modular grid patterns, free standing columns (pilotis) with recessed glass walls on ground level, “brise-soleil” sun screens, and long horizontal strip windows.
