In 1922 the "Maršalat" was adapted on the design of architect Momir Korunović. The original edifice was modest and ground-level, which hosted the royal guard. Korunović's design of the eastern façade was mostly plain, but the western, facing the court, was richly decorated with ornaments. The "Maršalat", including the Ministry of the Court and royal administration, occupied the central part of the building, while the wings had apartments for royal guests, which partially hastened the construction as it needed to host the guests of the royal wedding between King Alexander and Princess Maria.
