A mixed and condensed program which inspires an idea of global consistency: develop this "fragment of city in the city" like an organism composed of organs, �esh and �ows.

First by a void/solid reverse between existing building and projected building, by this way, preserved facades are drawing a patio, fossil mark of the old building, which is the lung, the hearth of the projected building.

Multitude of spaces and uses with speci�cs features are linked to compose a coherent unity in constant evolution and renewal wrapped up around its "lung".

This building is sculpted, cute, to let circulate the air and enter the light in its depth. It de�nes a contrast between the external skin homogeneity and the activity in the revealed �esh.

An "artery" network, like public space extensions, takes passer-by and users �ows through this density.

The external facade, like a "derm", contracts or dilates its pores network, according to features of uses and spaces it covers (ceiling height, light exposure) and writing a original partition, �ngerprint of the building.

Facades around internal gap let appear spaces of life and appropriation in constant evolution (interior garden, loggias), like individual housing extensions, providing a natural thermic regulation (summer and winter comfort).

The aim of this rehabilitation is to adapt volumes to an actual way of life. Previously very introverted because prone to bad weather. This Breton house will, from now on, capture sunlight and framing of this all west shore.

inside, very divided volumes are rede�ned as large crossing spaces.

De�nition of a housing typology combining generosity of uses, bene�ts of sunlight and exterior private spaces.Potentialities of a structure wich allows extension, transformation and appropriation of these housing.

It takes many social housing features into account, to be an alternative to it.

A work with the wall, component structuring the vegetable garden.

This project is based on the gap in an angle of a wall .

This angle creates a connection with the urban space, de�nes a student circulation and a visitor promenade.

Speci�c spaces are created to improve exchanges between visitors and students.

BREAKING DOWN, STRUCTURE + ENVELOPE

CONNECTIONS DETAILS

This high volum allows diversi�ed uses and exhibitions.

The structure is composed of a undertensed roof put on triple post providing the stability of the whole pavilion.

Openings at the top of each facade lets cables cross it and provides a natural air cooling system.Theses openings can be obstructed in winter by an isolating slip system. The roof layer extented beyond the facades becomes brise-soleil.Rainwater is drained round the back.

Plancher en poutres IPN sur lequel sont �xés les poteaux (évite tout travaux de fondations nécessite juste un système de cales) le plancher est contreventé par une trame de caillebotis en bois de 2m x 2m.

Plancher en poutres H �xé aux poteaux et au système de raidisseurs. Il participe au contreventement transversal du pavillon. Ce plancher est également contreventé par une trame de caillebotis en bois de 2m x 1,2m.

Poteau triples avec des angles d'assise su�sament ouverts pour assurer un contreventement longitudinale et transversale. Lors du montage des poteaux, des tirants temporaires les tiennent d'aplomb le temps d'y �xer la couverture.

L'enveloppe est constituée d'un système de raidisseurs situé à l'intérieur, derrière les parois. Il soutient les menuiseries qui encadrent des panneaux opaques isolants ou du double vitrage.

Système de sous-tension de la toiture: 4 bièles courtes travaillant en compressions transfèrent les e�orts de la poutre sous tendue vers 4 câbles travaillant en traction. les liaisons avec la toiture se font par un système de pannes supportant les di�érents constituants de la couverture.

La couverture est constituée de deux couches de tôle nervurée renfermant: un isolant thermique, un pare vapeur (tole d'un mm d'épaisseur), un isolant acoustique (contre la résonnance des eaux pluviales.

Transversal section (NW-SE).

Longitudinal section (SW-NE).

PROCESS : - Empty the stairwell

- Extend it to the place du 18 juin 1940 tu hang-up a pod, "distribution cube" in the dark layer of the Galeries Lafayette

- Work on this dark layer and its joint with the horizontal plane of the terrace (wich can be extended in overhanging).

- Unify the distribution cube and the emptyed stairwell (now a patio) to create a global volume expressing llinks between levels.

Connection of the terrace (place Jean Tossan) to the place du 18 Juin 1940PROBLEMS:

Analysis shows a lack of links between upper and lower levels. Theses two levels and the circulation are existing but are not expressed.

My project is to reveal the upper level from the lower and to create a transition perceptible from the street.

Contrast between a bright hanged cube and dark thick layer supported by a post framework. Only stairs and lift are extended and connected to the ground.

By night, from the street, the "skin" formed by a metal canvas hanged in the patio highlight it as a volume of di�used light.

On the terrace, the distribution pod is discreet (2,26 m height) to preserve the overview.

First approach of a mixed program in direct relationship with the site.(Exhibition space, restaurant, boarding stage)

Intentions:Connect the street, underground and embankment levelswith a large promenade in the axe of the dock.Merge the interior and exterior spaces to incite the visitorsto use the promenade.
