[Description]

LA MAISON PLEINE is dedicated to the youth, especially at the critical transition period from academic life to the professional world. Situated in the university area of Paris, this platform is meant for everyone who is creative, disregarding the area of interest, in order to be challenged in a place created for everyone: a platform of discussions, ideas and networking. The transport hub above the building responds to the mobility demands of an ever-growing city; the dwellers conjointly need a place of recreation, study, understanding, sharing and socialising. This platform of social life and intense collaborative work unfolds and spreads vertically, creating a larger open space in direct communication with the city. CONTINUOUS PUBLIC SPACE Our project opens and displays itself in the urban setting. We see it as a lever which strongly features the articulation of Paris and the Grand Paris. We explore a positive, critical and reactionary view of the CITY AS A MANUFACTURER OF THE PUBLIC GOOD AND WELFARE.La Maison Pleine is a Réinventer Paris Rive Gauche competition entry by Sensual City Studio and Jacques Ferrier Architectures, sited above the Petite Ceinture - the 32 km abandoned railway corridor that constitutes one of Paris's most significant urban voids. The project is dedicated to the critical transition between academic life and the professional world - a platform open to anyone who is creative, regardless of discipline. The programme unfolds vertically above the railway: FabLab, shared canteen, coworking space, youth housing, and cultural space are stacked in a porous building that reads as continuous public space from street to roofline. BfNA reading: this project is understood as a case study in movement, orientation, accessibility, safety, social mixing and collective behaviour. It extends beyond architectural production into environmental intelligence / how design decisions can support human adaptation, social responsibility, ecological performance and future evidence-based practice.

[Key Figures]

Typology: urban mixed-use · 2015 · ~15,000 m2 · Programme: FabLab + youth hostel + open canteen + cultural space + housing · Site: above the Petite Ceinture (Paris-Ivry) · Réinventer Paris Rive Gauche

[Neural Analysis]

CARE CHEMISTRY: Family architecture can regulate stress through predictable thresholds, playful cues and spaces that support oxytocin-linked bonding without sensory saturation.

TRANSITION VULNERABILITY [B2][A3]: The school-to-work transition (18-25 yrs) is the period of maximum neurological vulnerability for anxiety, depression and identity disorders (WHO 2023, Lancet Psychiatry). Third-place creates conditions for protective social contact - MacKerron & Mourato (2013): being with others (vs alone) is one of the strongest positive-affect correlates [S1]. CREATIVE COLLISION [B3][S2]: Interdisciplinary mix stimulates creativity via associative learning and neuroplasticity. Kaplan ART (1995): informal nature-adjacent resting zones restore directed attention between cognitive work sessions [S2]. ACOUSTICS [A3]: FabLab requires 55-65 dB working zones; reading/study requires <40 dB - acoustic zoning within one building. LIGHT [L1][L4]: Youth hostel orientation maximises morning daylight for circadian regulation [L1]. ADOLESCENT NEUROPLASTICITY & THIRD PLACE [S1][B2]: Blakemore (2018, Inventing Ourselves): ages 18-25 represent peak neuroplasticity and maximum vulnerability for identity formation and anxiety onset. Oldenburg's "third place" (1989) is most critically absent for this age group. La Maison Pleine's coworking + fab lab + shared canteen creates the exact spatial safety net this demographic requires. MacKerron & Mourato (2013): being with others in a comfortable shared space is among the top 3 positive-affect activities. BfNA neural-sciences lens: the relevant question is not only how the project looks, but how it conditions movement, orientation, accessibility, safety, social mixing and collective behaviour over time, across different bodies, neurotypes and social realities.

[Social Impact]

SOCIAL: The project treats care infrastructure as civic architecture, not residual service space.

[ROI Sustainability]

ROI: Better care environments may reduce stress for children, families and staff while improving use intensity.

ROI: Réinventer Paris competition: successful entries attract public-private funding. Petite Ceinture air rights are a major Paris real estate opportunity. SUSTAINABILITY: Above-infrastructure build: no land take; reactivates disused rail corridor as urban spine. CREATIVE ECONOMY ROI: FabLab + coworking generates multiple revenue streams: membership (€150-300/month), event rental, workshop programmes. Canteen: 200 covers/day. Paris 13ème: fastest-appreciating arrondissement 2015-2024 (+65%). ESG / investment lens: the value of this project is not limited to carbon or certification. It includes public value, climate adaptation, inclusion and civic resilience, producing evidence that can inform investors, public actors, operators and future environmental standards.

[Applied R&D Lens]

Measure sensory load, caregiver stress and child exploration across play, waiting and retreat zones.

The 18-25 age group is the highest-risk period for depression onset - and the most spatially underserved. BfNA's Applied R&D would deploy longitudinal depression and anxiety screening (PHQ-9, GAD-7) across La Maison Pleine's resident and user population, correlated with social contact frequency, creative activity hours, and food access. The shared canteen, FabLab, and coworking space provide three independently measurable neural protection factors: social contact, creative agency, and economic security. The Petite Ceinture location adds a spatial variable - above-infrastructure dwelling as a neural condition. Does proximity to the void below affect the adaptive functioning of those who live above it?Future data layer: deployed through BfNA, the project could become a longitudinal dataset linking environmental conditions, behavioural patterns, social outcomes and ecological performance / transforming built space into knowledge for future design.
