Unioninkatu 18


The magnificent roof terrace with a sea view is a memorable detail in the Unioninkatu office and retail property. Several upscale restaurants and hotels are located within a short walking distance. Other crown jewels of the city centre are also located nearby, such as the Old Market Hall and the Tähtitorninmäki and Esplanadi parks.

The building, completed in the 1930s, houses retail space with large windows on the street level. The premises of this former residential building are comfortable and convertible into offices or an open-plan office. All floors are equipped with balconies to two directions. The tenants can also utilise the modern conference services available in the building next door.
Private parking garages with a total of 1,000 monitored parking spaces are available in the vicinity.
In addition, there is plenty of parking space available in the Old Market Hall parking lot.
Trams 1, 2 and 3 stop at the nearby Market Square, and the metro and railway stations are not far away either. Despite the central location, the surroundings are quiet.
