Tietokuja 2

How do you transform a monofunctional headquarters from the techy 80s into a modern workplace? In Helsinki, we’ve gradually highlighted the qualities of this culturally classified building, adapted it to new needs, and let its history play along with the future. Tietokuja 2 has now come back to life.

The office building was designed by architect Osmo Lappo and opened in the early 1980s as IBM’s Finnish headquarters. With its 36,000 m², it was a giant of its time – but eventually, one that became too large for a single company. During the 2010s, parts of the property were rented out, and eventually, it was time for more substantial changes. Tengbom has worked with the property since 2012.

“A characteristic waffle slab roof in concrete, typical of Lappo’s constructivist design language.”

An upgraded lobby with respect for the original

The main entrance has received a new design with a wider staircase and a new roof – elements that make the space more welcoming and intuitive. The staircase now serves as a natural guide to the meeting rooms on the upper floor.

Otherwise, the lobby has been carefully modernized. Only minor structural interventions were needed, while surfaces, furnishings, and lighting have been updated. Beneath the new floors, the original tiling remains.

Waffle ceiling in a new color

During the renovation of the restaurant, we discovered a hidden design element: a characteristic waffle ceiling in concrete, typical of Lappo’s constructivist style. We chose to make it visible and painted it orange – a color that emphasizes the detail’s unique character.

The design team reintegrated the ceiling into the restaurant environment to give the room a strong identity. They used the same ceiling in the bicycle parking area, pairing it with social functions such as bike service and changing rooms.

A building in constant development

In addition to the restaurant and meeting areas, we’ve designed a new commercial gym (Ole.Fit Munkka gym), improved staff facilities – and ensured that the functions support a smoother everyday life and a more attractive work environment.

— At the same time, the new zoning plan has protected the building with an SR-3 classification. This means we preserve the historical values while bringing the building into the future, says Petrus Laaksonen, lead architect.

And the development continues: a veterinary clinic has already opened, and work is underway to transform other parts of the building into a hospital, a care facility for people with dementia, and an upper secondary school. We follow the transformation of Tietokuja 2 with curiosity.
