Designed building is a part of a business complex, located in the business zone Gacka, Osijek. Complex is consisted of 3 buildings interconnected by underground garage and platform at the level of the first floor. Building is located along the western edge of the plot. Architectural concept is based on the contrast between open and closed, public and private. Departments of the building are grouped according to the characters of the workplace. Characteristically “serious” departments are located on the south, quieter side, while creative departments are located next to the market and the center of the plot. The logic of grouping departments according to character continues in floor plan organizations as well. Floor plans are designed as a rhythm of open and closed space, which changes its direction depending on the need. Contrast is continued in the design of the facade and the choice of materials. Southern part of a building is coverd with perforated full surfaced metal sheet and thus communicates with the design of outbuildings. North side is completely transparent, decorated with vertically placed wooden beams ending on a green roof terrace. Openness, greenery and wood communicate with the green market. The main idea of the project was with separation and contrast of different characters of space, materials and atmosphere, merging building and its individual parts, and building with an urban solution into one designed and functional whole.
