Olafur Eliasson (Copenhagen, 1967) is not an architect but rather an artist of space; since the Danish artist’s studio opened in Berlin in 1995, he has explored the workings of perception, movement and human relationship to the environment. Conceiving of the artwork as something relevant for society, he exploits its universal vocabulary in projects of denouncement, meant to change the usual way of perceiving natural events or physical phenomena such as light. His artworks take the form of installations, sculptures, paintings, photographs or films and, bypassing museum spaces, they enter the public domain by becoming temporary architecture or collective actions. Paradigmatic of this development was the installation titled Ice Watch(2018) outside the Tate Modern in London, in which 12 large blocks of ice that had detached from the Greenland ice sheet were arranged in a circle, as if marking the hours on a clock face. The artwork created a tangible experience while declaring the reality of the melting of Arctic ice. Another example is the spectacular Waterfall, built for the gardens of Versailles (2016): supported by a pylon, the flow of the water called attention to the presence of greater natural forces as these play off our artificial environments. Parallel to producing this kind of artwork, Eliasson’s interest in architecture continued to grow and culminated, in 2014, in the founding of Studio Other Spaces with architect Sebastian Behmann. Located in Berlin in the same building as the Studio Olafur Eliasson, SOS allows the artist and the architect to test, in an interdisciplinary way, a new concept of public space; among the works moving in this direction we recall here the Cirkelbroen bridge in Copenhagen (2015), composed of five offset circular platforms that form flat connecting boat shapes, encouraging those who pass over the bridge to linger. The most emblematic work is Fjordenhus (2018), an SOE project that was developed in close collaboration with SOS facing the port of Vejle, on the Danish peninsula of the Jutland. This building in brick, sculpted by parabolic arches that seems to emerge from the depths of the sea and rise to a height of 28 metres, serves as the new headquarters of the Danish firm Kirk Kapital and is intended as a total work of art, with especially-designed furniture and lighting, as well as some site-specific artworks.
