Korkeavuorenkatu 35


Designed by architect Lars Sonck, Korkeavuorenkatu 35 is an impressive stone building in Art Nouveau style. This premium historic building was completed in 1907 and originally served as the headquarters of the Helsinki Telephone Association.

It is situated in an excellent location in a premium area in the centre of Helsinki. The location has excellent public transport connections. The services of the city centre are all within a short distance.

In 2011, the exterior and interior of the building were renovated and converted into modern office facilities in collaboration with the Helsinki City Museum. The magnificent facade and staircase of the building are protected architectural features. This unique Kivilinna property has 2,699 m2 of modern and premium office space for rent, and the facilities can be adjusted to tenants’ specific needs.
