GO21, office block and parking facility, Tampere

The facility consists of a 3–9-storey commercial and office building with 1–2 underground floors (K1 and K2) primarily used for parking. The complex is formed by three office space sections of various heights that are linked to one another via lower office sections and a parking facility. The consequence class of the tallest part of the complex is CC3 and the lower sections are of the class CC2.

The building is built partly on piles and partly on ground-based foundations.
The frame has a column-beam structure with the stairwells and parts of the façades serving as stabilising structures.
