Bridging Urban Heritage and Contemporary Living: 24 Social Housing Units, Vincennes by Prinvault Architectes

Delivered in 2025, the project 24 Social Housing Units by Prinvault Architectes contributes to the ongoing transformation of Vincennes’ dense urban fabric while reinforcing its architectural continuity. Commissioned by LogiRep (Polylogis Group), the development provides 24 social housing units alongside a retail space, aligning with the city’s long-term objective to increase its social housing stock, from 5% in 2002 to 12% in 2025.

Social Housing as Urban Continuity

Set within an early 20th-century context characterized by a mix of recessed single-family homes and five-story apartment buildings, the project negotiates between historical presence and contemporary needs.

Responding to a Complex Urban Context

The site stretches between Diderot and Jarry streets, requiring careful alignment to maintain the existing street rhythm and strengthen urban continuity. One of the principal challenges was achieving this alignment while preserving a building depth that would allow generous, well-lit, and functional dwellings.

Rather than treating the plot as a singular mass, the architects divided the program into two distinct volumes, ensuring both contextual sensitivity and residential quality.

Two Volumes, One Cohesive System

The project is organized into two built entities connected by a central footbridge and staircase. This configuration creates a spatial dialogue between the two volumes while allowing light, air, and visual connections to pass through the heart of the development.

This central circulation element becomes both a functional connector and an architectural mediator, enabling contrasting interior and exterior expressions while maintaining a coherent whole.

Brick as a Language of Belonging

On the street-facing façades, brick is used as the primary material, anchoring the project within Vincennes’ architectural heritage. The façades feature a distinctive “gear-tooth” pattern, created through alternating diagonal headers and straight stretchers. This subtle articulation gives depth and rhythm to the elevations, enriching the streetscape without resorting to formal pastiche.

Through this careful reinterpretation of traditional masonry, the building integrates seamlessly into its surroundings, reinforcing a sense of continuity and belonging.

Contemporary Interiors and Light-Filled Living

In contrast to the contextual solidity of the exterior, the interior spaces adopt a distinctly contemporary language. Bright living areas are finished with stained patterned concrete and complemented by metal screens, creating a refined yet robust domestic atmosphere.

The housing mix, 18 one-bedroom units and 6 three-bedroom units, responds to diverse household needs. Generous glazing ensures ample natural light, while thoughtful layouts prioritize comfort, usability, and long-term livability.

Balancing Density and Quality

With a total floor area of 1,140 m², the project demonstrates how density can coexist with quality in social housing. The careful modulation of volumes, circulation, and material expression allows the building to meet regulatory and urban constraints without compromising residential dignity.

The inclusion of a retail space at ground level further strengthens the project’s relationship with the street, activating the urban edge and contributing to daily neighborhood life.

Social Housing as Architectural Responsibility

Rather than treating social housing as a purely functional exercise, Prinvault Architectes approach the project as an opportunity to reinforce urban identity, architectural continuity, and social value. By bridging past and present through material language and spatial organization, the project affirms the role of architecture in shaping inclusive, well-integrated urban environments.
