Promoter: Elogie
Allotment rule: There is different allotment rules for three different public tenants: 1) Ville de Paris (4 housing units) selects 3 candidates ranked by highest priority ; 2) Préfécture (3 housing units) presents 2 ill-housed “DALO” candidates ranked by priority ; 3) Logeo (2 housing units) selects candidates with modest revenues
Reduction cost percentage compared to the market value:
– assignement: – 65,46 % compared to market
– rent: – 65,46 % compared to market


Cost of construction max:
– The cost was carefully controlled thanks to the use of a simple and efficient structure (prefabrication and rational distributions) and a very performant and long-lasting thermal enveloppe which reduces long term costs.
Rental/sale cost compared to market price: not known


Rules of allocation:
-Different allotment rules for the three different public tenants :
– Ville de Paris (4 housing units) selects 3 candidates ranked by highest priority
– Préfécture (3 housing units) presents 2 ill-housed “DALO” candidates ranked by priority
– Logeo (2 housing units) selects candidates with modest revenues
Protection of fragile categories:
– The project is for three distinct populations:
– PLAI system for high precarity people
– PLUS system for a population targeted by the public housing standards
– PLS system for families whose revenues are too high to obtain a standard public housing but too low to find housing in the private sector
Involvement of inhabitants in the building process:
There was no participation from the inhabitants in the building process.
Community accompaniment in the life of the building:
A welcoming event has been organized with the builder and the inhabitants, and guides presenting the architectural and social aspects of the project have been distributed to them.


Functional mixitè: The building includes in the ground floor level a commercial space of 50sqm, occupied today by a specialist of electric bicycles.
Common spaces and shared living:
A careful attention has been given to the common circulations. The transparent entrance hall links views from the street to the inner planted courtyard, and the stairwell is filled with natural light as in traditional Haussmann buildings.
Techniques and strategies for environmental saving:
The project’s very performant enveloppe (40,8 W/sqm.year) and its noble construction materials used to last in time make it a sustainable building capable of stand the passing of time.
Certifications: Effinergie +,Plan Climat de la Ville de Paris, H&E profil A

Description of the project: 

How to build nowadays social housing in a district of Paris which has a strong Haussmann identity, and at the same time how to answer the challenges of today, and among them sustainability? 

The building shows its belonging to the Parisian history and at the same time its modernity in the Parisian urban landscape. 

The street façade plays with the contradiction and complexity between historical and contemporary, between verticality and horizontality, between alignments and shifts, between light and shadows, between mineral and vegetal.


The façade develops themes of the Parisian Architecture such as composition and materiality: wooden vertical windows, mineral materiality, high level ground floor, horizontal cornices… The façade is treated with a noble, massive and sustainable materiality: an architectonic prefabricated concrete, a contemporary material which is one of the substitutes of the carrier stone. These prefab elements are bearing-parts of the structural concept of the project, and their color is a middle warm grey which reacts differently according to the moment of the day and to the weather.

The hall is a transversal space connecting the street with the inner courtyard, planted with a majestic chestnut tree. The organisation of the dwellings inspires itself from Haussmann apartments principles with representative spaces oriented towards the street, and bedrooms towards the courtyard. All the apartments, except the studios, have a double orientation. The typologies are organised around a watercore composed from the bathroom, toilet and kitchen. Ones can walk all around this watercore, creating a dilatation effect of the space.

The building is highly insulated with a very effective thermal skin, with an energy supply of 40   Watt/m².year and an air-proof skin of 0,20 m3/m².h which is similar to Passiv’Haus certification.

The project believes in the capacity of the Haussmann template to cross the ages.
