Dealing with a typical urban site, Niemeyer adopted creative solutions to enliven the otherwise monolithic high rise, thus challenging the predominant solidity which was the norm for bank buildings.[17"> The glazed south façade (with least insulation) reflects the 19th century Candelária Church, showing Niemeyer's sensitivity to the surroundings and older architecture. Such austere designs to high rises within urban grids can also be seen in the Edifício Montreal (1951–1954), Edifício Triângulo (1955) and the Edifício Sede do Banco Mineiro da Produção.
