Directed by Laura Ulloa, BfNA explores and designs for the reciprocal dynamics between environments, cognition and collective adaptation.

URBAN RESPONSE Finding a flow in order to implement a mass and void procuring a sense of a space dedicated to its public urban function, adding a programmatic value to enhance the medieval context of the city. The two buildings, as an extension of the city hall, re-define the space and flow of the inhabitants and visitors. One can spend time outside and inside without being an active agent within the building, but using the public space to one's own needs. Going up the stairs, it detaches one from the original public, entering the void - visually and physically - rendering all the possibilities which the space is capable of, and arriving to the C_ suspended monolith above the city offering its view. On top of it, one will find the D_ 'Paradise Garden' - the magical place to be surrounded by the city. PARADISE GARDEN Different levels of the city accompany the visitor to different perspectives of the city and then elevate the visitor onto a paved scenic square putting in scene the vast view. Here, a garden of beauty creates a multitude of scents and a spectrum of refined colours. A glass wall protects from wind and underlines the gardens' hidden charms.The Hôtel de Ville Chartres is a competition entry by Dietmar Feichtinger Architectes with VOGT Landscape Architects for the renovation and extension of Chartres' town hall, in the shadow of the Gothic cathedral (UNESCO World Heritage, 2.5M visitors/year). Two new volumes redefine the movement and spatial experience of the civic complex. The ascent through the building culminates in the Paradise Garden: an aromatic rooftop landscape offering views of the cathedral and the city. The garden's planting - lavender, rosemary, thyme, rose - creates a spectrum of colour and a multitude of scents at the highest publicly accessible point of the civic building. Landscape: VOGT Landscape Architects. BfNA reading: this project is understood as a case study in human-environment interaction, behavioural adaptation and contextual spatial experience. It extends beyond architectural production into environmental intelligence / how design decisions can support human adaptation, social responsibility, ecological performance and future evidence-based practice.
Typology: civic _ townhall · 2012 · ~12,000 m2 · Programme: town hall + public spaces + Paradise Garden (rooftop) · Views: Chartres Cathedral · Medieval context
CIVIC LEGIBILITY: A town hall regulates the citizen's relation to authority through access, light and orientation; clarity can lower anxiety and support trust.
PARADISE GARDEN & MULTISENSORY RESTORATION [B3][B5][S2]: Rooftop aromatic garden activates olfactory memory (most direct sensory pathway to the hippocampus and limbic system - Herz, 2000, Psych. Research). Multi-colour flowering spectrum activates visual cortex pleasure circuits. Kaplan ART (1995): gardens as restorative environments - 'being away' + 'extent' + 'soft fascination' all met by the Paradise Garden [S2]. Gaekwad et al. (2023) meta-analysis confirms parasympathetic activation from nature exposure [B5]. LIGHT [L1]: Cathedral views - Gothic stone + daylight filtering through the garden - create circadian-aligned luminous experience; morning cortisol regulation improved by adequate daylight [L1]. INSTITUTIONAL ADAPTIVE FUNCTIONING [A3]: Government workers require the 40-55 dB acoustic zone [A3] and regular restorative breaks - the Paradise Garden provides exactly this. PARADISE GARDEN & MULTISENSORY RESTORATION [B3][B5][S2]: The Paradise Garden roof activates all five senses simultaneously: olfactory (aromatic plants, the most direct hippocampal pathway - Herz, 2016), visual (multi-colour bloom spectrum), tactile (varied textures), auditory (birdsong, wind) and taste (edible plants). Kaplan (1995) ART: this combination of sensory variety within structured composition produces the deepest restorative state. BfNA neural-sciences lens: the relevant question is not only how the project looks, but how it conditions human-environment interaction, behavioural adaptation and contextual spatial experience over time, across different bodies, neurotypes and social realities.
SOCIAL: The project strengthens the town hall as an accessible civic anchor rather than a remote administrative object.
ROI: Public-value return emerges through better service access, heritage continuity and civic identity.
ROI: Town hall as landmark public investment; Paradise Garden generates tourism and civic pride. Chartres is a World Heritage Site (Cathedral): quality architecture drives heritage tourism. SUSTAINABILITY: VOGT Landscape: aromatic garden with drought-resistant local species; rooftop garden reduces heat load 15-20%. HERITAGE CITY INVESTMENT: Quality contemporary architecture enhances heritage tourism value (ICOMOS, 2021). Aromatic garden: zero irrigation (drought-tolerant Mediterranean plants); self-seeding in Eure-et-Loir climate; 50-year maintenance cost near-zero. ESG / investment lens: the value of this project is not limited to carbon or certification. It includes ESG value, social impact and future spatial intelligence, producing evidence that can inform investors, public actors, operators and future environmental standards.
Study entry stress, wayfinding success and perceived welcome before and after garden/threshold interventions.
The Paradise Garden creates the most precisely measurable olfactory neural science condition in this portfolio. BfNA's Applied R&D would deploy olfactometry - quantitative measurement of aromatic compound concentrations across the garden's seasonal bloom cycle - correlated with galvanic skin response, hippocampal memory recall tests, and self-reported emotional valence in garden visitors. Herz's olfactory memory protocol provides the measurement framework: the garden as a Proustian instrument, its neural impact varying by season, by visitor history, by time of day. The roof of a town hall as the most precisely calibrated olfactory measurement station in the Eure-et-Loir.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.
