Currently, there are small residential houses on the north and west of the area and green meadow to the east and south. Volkswagen car plant in the northeast complements mono-functional buildings. Parcel where the administrative center is located is currently not built up. According to master plan, the area should be used for the construction of housing and community amenities.

On the north side, administrative blocks serving as an eye-catcher, its shape is as lean over the Ján Jonáš Street. The original shape of the terrain reminds mound before administration. The proposed floor plan is X-shaped, consisting of rental units for shops and services, supplemented by three rectangles with administration function. Therefore it is named as Trix. Walkways above Ján Jonáš Street are adding elegant look to the building and are making a comfortable passage for pedestrians and cyclists. Important role plays active and passive use of solar energy, which determined roof shape. The result of the thesis was to create architectural studies.
