MONOLOGO (Monong Coffee) is located in the industrial landscape protection area of ​​Beijing’s 751 Park. This site includes a furnace tank area on the south side of the original 751 plant which has been wholly preserved, while a vast open space spreads between the west side and the main road cutting through the park. The core part of the site is a factory building with a concrete frame structure dating back to the 1970s. Three imposing furnace tanks are preserved in the center of the site. Two yellow and black steel structures were added to the south, east and west corners of the plant on two separate occasions. Our renovation project should be counted as the fourth "extension" of the site. We hope that memories of former interventions may be fully preserved, and through this project, they will eventually be connected into a cohesive narrative.
