Amsterdam based Jongert en Jongert gallery works on a very nice public space project at their doorstep. Since a whole block of neighbouring houses are renovated, about 70 panel doors were rejected by the housing cooperation, since they do not meet todays standards for sound insulation.
Jongert en Jongert took them out in the street and reintegrated them in spatial paintings, protecting the trees from future buildingmachines.
