There are viewing decks throughout the tower; some of them are designed as outdoor gardens, like the one at +32.8 and + 116m. Others are indoor, like the observation levels at +168m and +459.2 and +454m.
The indoor decks have attached to them fully glazed triangular boxes that protrude several meters out of the building.
These give visitors the possibility to step out off the building and have a unobstructed panoramic view of the city surrounding it. These boxes have a glazed floor making the experience of stepping out of the building extra exciting while looking to the ground below.
