The housing parisians built between the wars along the boulevards of the Marshals, on the edge of the capital, constitute a case of school architectural : in order to preserve this heritage – all in anticipation of the thermal renovation of magnitude – the parisian Agency for urbanism has carried out an extensive study to better understand their design. Details.
The implementation of the Climate Plan of the City of Paris has focused in recent years on buildings constructed between the 1950s and 1970s, thermally decayed, but “easy” to rehabilitate. On the other hand, the Housing cheap so-called “HBM”, the ancestors of the HOUSING estate, built in the period Between the two world wars have been left aside, because the policies of renovation of their are not easily transposable. Was this a main reason : their particularism architectural and heritage value.
Implanted straight-line method over the former right of way of “the Zone”, along the boulevard des Maréchaux sequences with sometimes long, nearly a kilometre (and totalling 17 km in all), these homes are distinguished by the use of the brick. A material commonly used in the capital, including the haussmann, but that is rarely left visible except on the courtyard side. This brick “are involved in the identification of these sets, “says the Agency in paris d’urbanisme (Apur) in the introduction of a comprehensive study devoted to the issue. The document, 128 pages, analyzes and dissects the buildings to better preserve their character at the time of their inevitable thermal rehabilitation.
A second historical study in preparation
- Big data : the 20 districts of paris dissected by the Apur
- A thermal renovation easy with a chimney, 3-in-1
Thus arises “the question of the knowledge of these buildings and their logic in terms of design : materials of construction, heating, water supply, composition of the open space, sunlight, ventilation, etc“. The Apur fills a deficit of information on these topics which made it difficult, up here, the work of the masters work in compiling historical data. All aspects have been addressed, whether it’s designers and managers, design and urban planning with the shape and size of the islands, the morphology of the building, or the construction techniques of the foundations to the roof, passing by the facades and floors. The aspect of stylistic calepinages reveals, for example, infinite variation, despite the apparent uniqueness. On the side of the housing, their typology is extensively detailed, as well as their level of comfort or benefits associated (empty-junk, chimneys).
The document, very comprehensive, is only a first step in the work of the Apur, which is already planning to publish a second study. This time, the work will be conducted in partnership with the Anru and the main social landlords of the HBM of the belt of Paris (Paris Habitat, RIVP, Elogie). He will address “the evolution of the park over time (…) will retrace the major generations of interventions carried out within the HBM and capitalize on the lessons learned by their managers“. This second step will address the issues of the thermal rehabilitation of these buildings that mark the city and represent an important step in its development.
