Our thesis project is about more of a design practice than a building structure. Alternating parameters of urban habitation we create new living models, aiming at a strategy that someone can follow at any level, regarding his needs.

Our staring point is the circulation system, a central core for the structure designed as a continuity of the street, therefore an open public space. It is about two stairs with different orientation leading to different parallel alleyways forming a dna shaped staircase. Its two stairways are independent. There is visual contact but access is impossible.The apartments are attached to the staircase in pairs. Each apartment is typically partitioned in two, given the advantage of autonomy of a person or a procedure. The housing units range from 25m2 to 100m2 on a grid plan of 5m providing at least one private balcony and access to public spaces.

The project is in fact a catalogue of versions. This strategy of vertical development, with staircaseunits creating a residential building, is applied under 4 possible versions of bountaries. Therefore, 4 structures are produced and subsequently, 4 blocks as a combination of these structures. Staircaseunits, always used in the perimeter of free space, create an open circulation system, that in both axes links public, semi-public and private space. Public terraces are accessible from the street and their size is adjusted in any occasion with the retraction of perforated metal panels.
