Grossmann House. The functionalist building was built by the Žilina merchant Adolf Grosmann between 1928 and 1930. The house was designed by the prominent architect Jozef Zweigenthal. Old Žilina inhabitants refer to the house as "Spitzer House" because Dr. Simon Spitzer, Grosmann's son-in-law, both practiced and lived in this house. He was a well-known doctor of the town during the period of the First Czechoslovak Republic. Originally, before 1928, there were two ground-floor houses on the plot where the present building stands. In one of them the butcher's guild had a slaughterhouse. Members of the butchers' guild owned the house until 1927, when it was sold to Grosmann. The house has a remarkable corner made of unplastered bricks. The ground floor ground floor is lightened by large glazed shopfronts.
