Abstract: In the period between the two world wars, Zagreb did not have a general regulatory basis according to which it would develop. Partial regulatory bases are created for individual areas. The western part of the city, which is bounded by the Republic of Austria Street in the east, Ilica in the north, the railway line in the south and the Črnomerca stream in the west, and which was included in the Regulatory basis from 1887 as an extension of the Lower Town, is being built by interpolating the blocks according to several regulatory bases created for individual regions. Industrial complexes, which at that time had priority over military ones, did not leave a significant urban element in the urban sense, and exceptions are rare, such as the administration building of the Factory "Hinka Francka sinovi d.d.". The construction in the western part of Zagreb between the two world wars was of a lower design and, in terms of construction, of lower quality than the previous era.
Keywords: Zagreb, Regulatory basis of Zagreb, Industrial architecture between the two world wars
