The completion of town hall in 1988 added the finishing touch to the administrative and cultural centre. The complex consists of several divergent wings and hierachically the most important premises are concentrated on the part facing the Hallituskatu street. The town council chamber and the conference room of the executive board are in the first floor where town manager and the chairman of the executive board also have their rooms. The building complex is dominated by the mass of the council chamber, the shape of which is outlined crystal like owing to the folded wall surfaces.

The interior architecture of the building is spacious and light. Light coloured surfaces are enlivened by wooden details. In the ground floor lobby is repeatedly used, as in Lappia hall, limestone from Loue. Furnishings by Artek and in Aalto's office designed lamps are also dominating the town hall interiors.
