The painted decoration of the interior was done by Dragutin Inkiostri Medenjak and gingerbread by Paško Vučetić.

It is designed as a free structure, withdrawn to the street, with a basis in the form of the Cyrillic letter "Ш".

The concept includes a major longitudinal tract, with prominent central projection, and three transverse backyard wings, of which is a medium significantly shorter.

The central projection of the main facade is very pronounced, as part of the caryatids on the entrance portal of the building.

Columns are duplicated on the floor, together with a rich plastic decoration of windows and three bronze busts - Dositej Obradovic, Vuk Karadzic, Joseph Pančić, of renowned sculptor Petar Ubavkić.
