Through stories illuminating the various facets of "home", this notion was explored to understand how architects can shape it. In the rehabilitation of an office block into housing, the aim is to imagine experimental dwellings that explore people's ability to make a place their own. On several floors, the narrow layout provides a doorstep onto the street for everyone, encouraging encounters and community. Earth walls, with hollowed-out niches, provide comfort and anchor memory. Preserved pre-existing structural cores are transformed into residual micro-rooms for free use. Houses become places to explore, where you can lose yourself. Crucial to the health of a city, the house must be made to tell the story of those who live in it.

«Give the ground back to the city through the conservation of a historically and socially anchored place». The challenge here is to reuse this pre-existing connection to the urban and to the citizens in order to continue its story and propose a theatre offer, at the service of the community and the territory. A new structure carried by the wind dialogues with the existing between which the theatre comes to life, narrates and thrives. This first large-scale project involved working intensively together to get to grips with it and come up with a project that was jointly thought through, designed and modelled.

CHEMINS DE FAIRE, WATER'S POTENTIAL

3rd semester, 2nd year

This wooden structure at an isolated crossroads fosters symbiosis with its environment and users. Its modular, rail-based design supports diverse functions of urban agriculture to emergency housing. The porous roof mimics living skin, collecting and filtering the water in clay pots, aiding local biodiversity and urban dynamism. Discussions and presentations guided our choice of site, and we worked together, contributing our respective skills.

The void only makes sense if it's in coproduction with the full. Its typology and the uses that take place there define it. These voids, which we call vacant spaces, have the objective of making the living cohabit: man and nature. Their analysis therefore makes it possible to grasp the stakes and the impact they have on the community at different scales. The purpose is to purify the voids, push their special qualities to their climax to encourage social and environmental development: as a vector of meeting, utilities, leisure and landscape. The city is an organism, the streets its veins and the voids its lungs. After discussions and site analyses, we worked together on each area, splitting up the drawings, which I then took over so that they fit in with the agreed graphic charter.

In the shade of date palms, an underground network of habitats follows the pattern of this nourishing palm grove. In the cool of the depths, hollowed-out cells meet the specific needs of the human body, and are ventilated by a common courtyard. Built from excavation waste, their interior temperatures are regulated by the thermal inertia of adobe, typical of the Kerman province where temperatures reach 40°C. Crossed by a staircase, these dwellings are integrated into a cellular ensemble, inspired by medinas. Drawing on the vernacular heritage, this complex organism creates a living fabric, adapted to the historical, natural and climatic context of Bam.

Bam (1) Drawing carpets inspired by Persian ones to express the city's DNA (2) The staircase archetype chosen to imagine a habitat adapted to the territory and its climate Being part of the local landscape (3) Habitat linked to dunes and elements (4) Rooms dug out of clay, inspired by local houses to consider inertia

Living with the wind and sand (5) Initial ideas for an architecture subjected to the climate: how to shelter, take advantage of gradual erosion?

Cellular grid (6) Designing the habitat according to a grid that will enable it to be extended or reduced (7) Navigating this grid via a staircase that walks like a public, communal and private labyrinth (8) Trying to solve, with the help of 3d modeling, the puzzle of the staircase that is both interior/exterior and public/common, yet does not intersect...
