Metropoles around the world are projected to keep growing in the coming years. Their population is increasing and with it the size and density of the city. Amsterdam is no exception to this projected growth with a population estimated to be larger than one million around 2050. As a consequence, we can see the housing and land prices skyrocket and the demand for new buildable space increase. ‘Green-House’ proposes to combine green recreation (allotment gardening) with the possibility for housing and hyper functional urban farming in a new architectural typology. With accessible green, it can sustain biodiversity in the city whilst embracing the densification and increasing the quality of life of the inhabitants with local food production.
