This massive corner building was constructed as an administrative and commercial house to complement the commercial network in the capital city. However, unlike Kotva or Máj, it was aimed at the wealthiest clientele. The design by architects Vlastibor Klimeš, Milan Vašek, and Vratislav Růžička won an international competition. Their plans included office spaces on the upper floors and luxury retail areas on the ground floor. The building features a protruding facade composed of a lightweight glass envelope with aluminum windows and substantial display cases, contrasting with the heavy limestone cladding. One reminder of the past is the yellow emblem of the Union of Czech and Moravian Production Cooperatives located on the corner facing Jindřišská Street. The building was constructed in parallel with the development of the Prague metro, so its first underground floor has an entrance from the metro vestibule. The building also includes a cylindrical extension housing the Duplex club.
