Client: Tjuvholmen Utvikling AS

Location: Oslo


Overlooking the fjord and the city center, Tjuvholmen Icon Tower is part of the new waterfront development in the center of Oslo. The tower represents a significant and iconic landmark as it identifies the new part of the city and announces the gateway the new Astrup Fearnley Museum, designed by Renzo Piano Building Workshop in association with Narud-Stokke-Wiig architects.

It also functions as an observation tower with an inbuilt public elevator, giving both locals and tourists the spectacular view of the capital and its surroundings.

The architectural character is emphasized by a continuous helical steel structure, supported by vertical legs and diagonal bracing rods. The geometry of the structure spirals around the elevator machinery and creates a relationship between the static nature of the steel and the vertical movement of the elevator. The façade is clad with extra clear white glass, curved and formed to follow the helical geometry of the steel. It is fixed only with corner bolts and silicon joints – making the cladding as transparent and light as possible.

The elevator cabin accommodates 6 persons and rises to about 55 meters above street level. At this level it makes a standstill for a few minutes, before slowly returning to the ground. It is specially designed and manufactured with curved glass walls and a glass roof in order to maximize the view. To avoid transparency towards the adjacent residential buildings – the use of electric smart-glass, with liquid crystals, allows the glass to switch from opaque to transparent as the lift raises above a certain level.
