APTO collaborated in a wide team of experts to create a concept that matched the high ambitions of the location. Podium F Amsterdam, the area next to Cornelis Lelylaan, will be developed as a metropolitan area with high density. With De Groene Stad, a vertical neighborhood was defined as a cornerstone and catalyst for the area. A community for a lifestyle of sharing, environmental awareness and working on the future together. Shared communal green on the roofs for urban farming, green facades for filtering dust particles from the air and a wide variety of energy reducing features were implemented to create this "Green City". APTO was responsible for both concept and architectural design.
