Open vs. enclosed
As though a clair-obscur, the gradient in the building’s plan is emphasized in the building’s contrasting façades. The Northern façade is mostly closed to reduce thermal loss and reduce sound exposure along the busy street. Towards the South the building opens up completely, maximizing passive solar gain and the connection with the outdoors. In between the two contrary façades, the building’s plan undergoes a gradual transformation, from compartmentalized in the North, to open-plan and structured with free-form elements towards the South. Here the building is concluded with a filter-like balcony layer.
Structured by circulation
Instead of reducing vertical circulation to a necessity, it occupies the heart of the building, optimizing the usage of space and facilitating flexibility in ownership. Omnipresent as a sculptural element in the lower apartment, the system gradually transforms into a series of voids higher up in the building.
