The residential building of Petar Petković, which housed an Opel representative office with retail space, is a typical urban interpolation, which in addition to the basic street block of the residential function has an extension to the ground floor in the second part of the plot. Therefore, the building had two separate entrances. The lack of a yard due to the engagement of the other part of the plot for the business annex was compensated by a roof terrace. In the narrow zone of the facade above the entrance, the name of the company O P E L was placed, but this imported “ornament” of modern architecture in a way opposed the relief compositions between the windows in the zone above, which Zloković often used on the facades of his buildings.
Kralja Milutina 33
Among several residential buildings designed for the Belgrade investor and owner Josif Šojat, an interpolated multi-storey building (residential building with rented apartments) in 33 Kralja Milutina Street stands out, with which Zloković brought the spirit of Mediterranean profane architecture into the Vračar city agglomeration, making several form gestures atypical for the previous Belgrade architecture.
