The beginning of the 1930s was marked by the European-wide economic crisis, while the second reason lay in the discontent of the highest state authorities by the selected project of architect Pičman, which in their opinion did not satisfy the requirements for representative and monumental architecture of public buildings.

Since the completion of the building, the part of the palace facing Takovska Street designed for the work of the Main Post Office has not changed its basic purpose, successively housing headquarters of the national postal services of Yugoslavia, and now Serbia.

New Androsov's project largely relied on the initial competition solution, which is primarily reflected in the decision of the base and disposition of space.

The highlighted avant-corps of the main facade, except that it shares the façade canvas into two unequal, asymmetrical parts, also reflects the internal functional division of the object.

Adjusting the modern concept of building to visually expressing the strength and prosperity of the new Yugoslav state and Belgrade as its capital with a representative academic base of its expression reflected the widely accepted attitude of the government with the monumental character of public buildings, designed in the style of high-academicism.

At the same time, the monumentality of the continent and the representativeness of the external processing classify it among the major examples of academic architecture of Belgrade.
