Text description provided by the architects. The Institute complex was designed between 1954 and 1962 by architect Danilo Kocjan, who envisioned low and elongated buildings, characteristic of Scandinavia, in a planted environment. The new building with the children's unit on the ground floor and the vocational rehabilitation unit on the first floor keeps in with the pavilion-like design. It is linked with the existing complex by means of the interjacent middle part housing the lifts.
The building itself has a rectangular floor plan with an internal atrium. The corridors and halls are well-lit and interesting. Along the sides of the atrium and the corridors, there are living spaces that open outwards into the exterior space with their wooden terraces. The large windows of the rooms and other spaces overlook the old park with the large trees, which have been retained despite the park's having been reduced in area.
The building fits organically into the planted environment. The basic facade, made of fibre cement panels with a smooth finish, is white with large horizontal window apertures and a rhythm of vertical yellow accents made of corrugated panels.
