Soho Deep Core, 2013

A monument, made of layers of concrete, which are added every year over the timescale of 130 years. The monument overtakes the entirety of current Golden Square and transforms the public space into a public void, that changes its character over time as it returns to its original function after 130 years.

The monument ultimately changes the area on a urban scale by reversing the use of the public space, disallowing acess to the site during construction works, reserving the streets of the promenade for pedestrians during the layering festival and by building the core 100 meters to the ground, stopping any future commercial building development in that area. It ensures that in 130 years, Golden Square will be a public space.

Model of the site with the void and the monument itself have been cast in plaster. Project has been done in collaboration with Oskar F. Johanson.
