Metalka was the first business 15-storey high-rise building in Ljubljana since Neboticnik. Edo Mihevc designed the iconic office building on the model of the Seagram Building in New York. Metalka is designed as a narrow box wrapped in a unified coating of lightly hanging facade made from prefabricated aluminium, designed byBranko Krasevac. The facade is a symbol of technological progress and ingenuity of the metal wholesaler who manufactured it. Metalka did in the 1960s what Neboticnik did in the 1930s; it proved that Slovenian architecture had kept pace with European development.
