History
In 1961, the government of Croatia announced a tender for a new building to house the Central Committee of the League of Communists of Croatia. A first prize was not awarded; instead, two-second prizes were awarded. Ivan Vitić's design received the "first second" prize, while and  from Skopje obtained the "second second" prize. The construction only began in 1963, as the building-to-be was located on undeveloped ground near the Sava river. The construction site was flooded in 1964, possibly inspiring Kockica's tall mezzanine. The building was completed in 1968. Because of its cubic shape, the citizens of Zagreb took to calling it the "little cube."

The Building was originally conceived as the third part of the complex, which was supposed to include a large conference hall (which would be a similar hall for the UN skyscraper). However, costs and overruns meant that part of the project has never been realized, but traces can still be seen today in form of the bridge supports designed to connect the hall with the main building.

Despite the bland outside appearance, the building's interior was richly decorated by the artists of the era. coordinated the effort and contributed artworks in glass, Jagoda Buić created the tapestry, while made the metal relief. The building also features mosaics by, wall paintings by Edo Murtić and at one time was home to a metal tapestry by Dušan Džamonja, which was stolen in the tumult of the 1990s. The building is protected as cultural heritage of the Republic of Croatia.
