The project starts from reappropriating two previous projects from the last semester in both East and West sides, connecting them through an infinite city of 100m wide with industrial genetics. In this colaborative way, the entire class organizes a continuous chain creating a mixed and compact city located in Detroit, introducing housing and other programs, and communicated not only by the different levels of the project but also by a public tramway.

Recognized industrial structures are the support of both projects, such as Ford Engineering Labs from Albert Kahn on the West side and B&B Italy from Renzo Piano & Richard Rogers on the East side. Moving out from this base, we have different structures, genetics, logics, programs, rythms, infills and systems that are the trigger to develop the pattern and connections between them.

This new system introduces variables of use in the support, connecting double-heights and suspended floors, growing at double the height in the tramway area and increasing density with the creation of the residential tower, element where both structures converge. It also takes advantage of the high degree of flexibility that the B&B structure offers for open-ended systems (by adding or subtracting), introducing in this way the neighbour's structure, mainly covered by a transparent material in order to transform it as a public space suitable for urban gardenings and greenhouses.

All of these bioclimatic decisions are both taken in the residential use: different housing typology (individual and duplex) with double façade to the exterior (cross ventilation and natural light), having as a terrace a "jardin d'hiver" (solar gain); and in the creation of an upper large greenhouse of 30 m height, using vegetation along all the project to increase energy efficency.

In the end, a connected, compact and multiprogrammed city is created, making possible the link between existing architectures by understanding both of them, valuing once again the potential of the post-industrial architecture.
