Prix des Espoirs de l'architecture BNP Paribas Real Estate 2025: 3/3 for ENSAPLV students!

Selected for the quality of its thinking and the relevance of its response to climate issues, the project offers a sensitive and innovative architectural response to the intensification of hydric episodes. It is located in a district of Rouen marked by urban isolation and a gradual rise in water levels, which could reach 1.5 meters by 2100.

Rather than fight against this climatic hazard, the project chooses to learn to live with it. The building becomes a neighborhood library, conceived as a veritable reservoir, capable of holding both knowledge and rainwater. Its vegetated first floor, designed as a free, porous soil, functions in calm weather as a public garden, and in wet weather is transformed into an amphibious landscape criss-crossed by pontoons.

Inside, the architecture is organized like a hydraulic machine. A central reservoir room can alternately host conferences or store water before redistributing it into reuse circuits. On the façade, a glazed double skin acts as a vertical tank, playing the role of winter garden or hydraulic container depending on climatic conditions.
By turning water from a constraint into a resource, “En attendant l’orage” proposes a model that can be reproduced on an urban scale. Multiplied throughout the city, these architectures would form a network of reservoirs capable of absorbing excess water while recreating social ties.

Inspired by Rem Koolhaas’s “New York délire”, this project asserts a critical and forward-looking stance: observing an ordinary territory and projecting an assumed vision of the city of tomorrow.
The term “délire” here is not synonymous with excess or absurdity, but with constructive utopia. It’s a question of taking the opposite view from a sometimes standardized urbanism to propose a more generous, more plant-based and more collective architecture.

The students imagined a green, eco-responsible building that would be open to its neighborhood, incorporating a semi-permeable planted square, planted terraces and a communal vegetable garden. The aim is to create a building that breathes, limits heat islands and encourages exchanges between residents.

In addition to environmental performance, the project emphasizes common spaces: a shared foyer, meeting places and intergenerational spaces. The “Bobigny Délire” project thus defends an architecture that goes beyond simple housing to recreate social links and imagine a more sustainable, collective and lively city.

Malaury Pierre and Maxime Caudrelier’s project received a total of 890 votes.

This project proposes the transformation of a vacant former bank branch in Guadeloupe into a nourishing and resilient place. Faced with intensifying rainfall, increasing heat and weakened soils, the architecture chooses to work with the tropical climate rather than constrain it.

Spaces are raised to anticipate rising water levels, soils are desilted to encourage infiltration, and natural ventilation provided by the trade winds limits the need for air conditioning. Using local resources such as coconut fibre and tropical wood, the building becomes an open ecosystem. A crèche, culinary workshops, a productive greenhouse and communal spaces breathe new life into the vacant tertiary sector, linking climate, food and social ties in a model that can be adapted to other exposed territories. The “From office to plate” project demonstrates that by rehabilitating existing buildings and drawing on local resources, architecture can become a concrete lever for climate resilience, while at the same time recreating spaces for sharing that are firmly rooted in their territory.
