Take Part: Update
Take Part is a project by Bik Van der Pol, seeks to create a shared public vision of the city by anchoring discussions about its past, present and future, to the tangible: a 1000 square foot detailed wooden scale model of the city built in the late 1930s by the WPA under the New Deal program.
(due to coronacrisis the final stage of this project is postponed)
