Cool Construction

For a better city during construction

We are extending the Copenhagen metro. Cool Construction is our way of turning construction site hoardings into temporary urban labs for the benefit of neighbours and passers-by. Cool Construction is financed by the sale of advertising space on dedicated parts of the hoardings.

Cool Construction was launched in 2011 and more than 100 projects are completed annually all around inner Copenhagen. We have selected a few cases below.

Case: #Happy Wall

Playful interaction creates a playground for all ages

Happy Wall was launched in April 2014. The artist, Thomas Dambo considered the wall a gift for the people of Copenhagen as well as the tourists. The manually interactive puzzle consisted of approximately 2000 wooden pixels that allow anyone to make their own huge art work on the wall. And there were always people here creating new shapes and messages!

Thomas Dambo is known for using recycled material and this huge piece is no exception. Happy Wall could be experienced at Kongens Nytorv until april 2015.

Case: Piles

Piles of dirt transformed into shiny organisms

Architects Pétur Örn Eyjólfsson og Søren Oskar Duvald created the piece Piles as an abstraction of the dirt, water and rubbles that is dug up from the underground during the construction of our new metro.

The piece was compiled of 45.546 small shiny aluminum disks in the formation of three piles on the hoardings at Kongens Nytorv. People were drawn to the lively flickering and surprisingly also started to interact with the piece by moving the disks around to form names and shapes.

Case: remixing art

Fine art remixed into street art

The National Gallery of Denmark has a program for young people who spend one year doing volunteer art projects. In 2013 the group presented the site-specific art piece that measures two times 30 metres in length on our hoardings near the great Marble Church.

The piece was designed in collaboration with some of the neighbours and is a remix of fine art, which is public domain and downloadable at
