Text description provided by the architects. The industrial city, the child of railways and automobiles, has itself given rise to a new urban form: the dense suburb. Predominantly residential, it contains detached, semi-detached, and row houses, sometimes even small, collective clusters of housing along its main roadways and intersections. For the sake of comfort, major roadways avoid cutting through such dense suburbs. Its proximity to a large city allows for other forms of mobility, whether individual (soft) or collective (public). Its density entails a maximal use of public facilities and the presence of neighborhood shops.

Greenery is omnipresent: in the yards one espies from the street, and in islands of coolness that occasionally become lines of trees in the public space. Buildings rarely exceed the height of the treetops, thus remaining hidden. The small, single-owner parcels facilitate densification and favor a rapid evolution in the buildings, hence, accelerating the historical stratification of the built environment. Dense suburban housing is a peaceful – for some, too peaceful – and almost invisible urban form that is rich in amenities. Its resilience has become highly relevant to the changes that people now expect of major metropolises.

These are the qualities that we sought to highlight in our reconstruction of a 1950s-era housing complex that was reaching the end of its useful life. The result of a consolidation of several parcels, these units optimized production processes, but they also created a gaping hole in the dense, surrounding housing.

Ground Floor Plan

The architecture made use of an industrial vernacular to reflect the coherence and diversity of dense suburban housing. How to use ordinary contemporary construction to create materiality, to give meaning to the material?

The project fragments the area by splitting up the parcels to develop an intermingled community of buildings and micro-forests. The various building typologies (simplex, duplex, single-family, row, intermediate, staggered, collective, single orientation, dual orientation, triple orientation, and windows on all sides) are expressed frugally, through concrete tinted in the colors of the materials used in the adjacent, ordinary buildings.

The joinery and architectural style of the windows, bases, and penthouse apartments are rigorously identical. In their refusal to engage in a pastiche, they embrace the program and its temporality, namely that the 66 housing units were built by the same team at the same time. Thus, as elsewhere in a dense suburban housing estate, the buildings are the same... and yet, different.

As is the case in a dense suburban housing estate, what matters is not the mass of the buildings, but rather the empty spaces. Greenery prevails, creating masks that limit visibility between the housing units, providing shade to the facades, and rendering the soil more permeable. It tempts one to ask, who was there first, the human beings or nature?
