The main concepts of our eco-machine are water control (flow and flooding) and vegetation (green roofs, green walls, daylighting). On a global scale, the building form is generated by the existing hydrology lines to create four main “neighborhood” boundaries. Each of these boundaries has three to seven units depending on its size. On the unit scale, the flow lines are translated to the concrete and wood material system to control and maintain water flow and directionality. This tectonic concrete system connects to our vegetation concept with its curvilinear forms that creates pocketing and opportunities for plant growth. Particular plants (hedera, aubrieta, clematis) were intentionally chosen to act as shading devices during the summer and spring before dying out in the fall and winter to optimize sunlight. In the cases where the water is not collected within these curvilinear moments, it will flow down into the bioswale in the ground floor before being directed back into the river.
