Charlie Koolhaas collaborated with Jan Sukkiennik and 137 Kilo architects on the Museum of Warsaw Praga - a new museum that would celebrate the dramatic history of Praga, an island attached to Warsaw city in Poland.

The museum opened in 2015 and Charlie Koolhaas worked to design the stories and installations based around the museums historical artefacts. 

She also took photographs of Praga in its current mode of rapid gentrification and made interviews with inhabitants, out of which she made two photographic installations for the museum that revealed the social problems that the area faces today.
