The building complex was designed to host all bureaus of the City Hall, previously divided and spread around the city. It has 3 distinctive parts: to the East are the offices – a 6 floor building about 100 m long, 15 m wide – with a prefabricated pretension-ed reinforced concrete structure, a building hosting the services in the center and a multilevel parking building with a capacity of 400 cars to the West side. Due to the low load capacity of the ground, concrete pilings have been used for the foundation. The air conditioning system has been located inside of an elliptical shape metal structure on top of the central building. The offices are open space.
