The Towers: This system grows vertically, to create new housing towers in a new way.
The towers that we designed have a vertical and continuous system of agricultural fields on the southern facade. They provide the central cores of each of the three buildings that rise above. These cores are where systems such as water and filtering run through.
They grow from the new urban structure and are designed according to the annual sun movement in order to allow agriculture to exist vertically in various medias and techniques – from low-tech detached soil to high-tech aeroponics. These growing ramps are “folded” plates within the steel structure to provide maximum sun light at different points inside the spiraled shape without breaking continuity.
The housing units are mostly duplex units with private outdoor patios.
Their configuration is according to sun shading in summer and exposure in winter.
At the top of the towers, we made use of “sun towers” – a technique used to maximize direct solar exposure to the southern facades of the housing units within the structure without having to compromise productive landscape inside the tower.
In light of the current eco-revolution of this age, we must conceptualize the city in a new way – as an organism, that is able to include agricultural processes and nature within it, thus enriching the urban environment and the variety of population that can enjoy it.
