Hembrug was back in the days responsible for the production and storage of weapons and ammunition for the Dutch army. The location has been chosen very carefully by the Stelling of Amsterdam and nowadays it is located between the two big growing cities Amsterdam and Zaandam. Because of is secrecy and abandoned, Hembrug can been seen as a new city! Through the time you can recognize different time layers of typologies on the terrain and it is now time to design the fifth generation of architecture on Hembrug. This will start with given the existing buildings new life with a function and to open up the buildings for public. Plofbos is one of the nine ensembles on Hembrug and is located in the middle heart of the terrain. The southern part is part of the production-zone, well the northern part of Plofbos belongs to the forest-zone. With his greenery environment and small scale buildings, Plofbos will be a new neighborhood of Hembrug with generation housing, and some supporting functions as well. A primary school and a community center are the design proposals for the fifth generation and will be characterized by new wooden entrances and their functions. The values of the typologies are different from each other; the Boerderijen have detailed monumental facades, well the shell roofs are formed by the spirit of place inside. This was also the design approach for the projects.
