GENESIS

« WHERE ARE YOU TAKING ME GRANDPA? » « OÙ M’EMMÈNES-TU GRAND-PÈRE? »

EN/FR

T

he story of a young artist named Foret, César Foret.

It all starts with the strong relationship between him and his grandfather. Named Albert Foret, the latter was also a painter and heir from father to son to a huge forest which was his space for creation and expression. The grandfather had a great affection for his grandson and shared his knowledge and mastery with him, teaching him to look at art and the art of drawing itself. The young Caesar lived his childhood among his great trees and developed a joy for life and found pleasure in this forest which was like his own.

Time passed and the young man found himself separated from the place in which he lived and grew up next to one for whom he held great esteem. The move from one universe to another will remain anchored in his memory. César leaves the forest and above all leaves his model, his grandfather. Albert gives his grandson a gift, which for him is of enormous value, but César, too young to understand, takes this notebook as a souvenir that he will learn to discover much later in his life. The gap widens and time passes.

The years pass and life takes its course when César, now an adult, learns that the man who had shaped his childhood has left this world. He constantly returns to memories with his grandfather that he has never erased from his life. The only thing Cesar takes with him is a sketchbook of his grandfather’s that lives deep in his memory. He finds this sketchbook hidden somewhere and decides to take it with him on his journey back to the forest. After all this time, he rediscovers the contents of the notebook which awakens feelings of nostalgia in him. He starts flipping through it again and again and stops at a drawing of his grandfather among a group of people in his forest. They are all standing in front of vegetation that César immediately recognises. He sees a scribbled part in the background of them. As he looks closer, he notices something that is abstract at the moment, but which has a great similarity with the sketches on the previous pages of the notebook. Until now, he had not paid attention to the details of the contents of the notebook. The trees he recognised in the drawing reminded him of his visits to the forest, which he wanted to find once he had arrived. On the spot, he retraces the steps of his childhood, which leads him, which takes him away, which is his domain. He sees this image that his memory brings up and recalls the stories his copy used to tell him. All this leads him to these trees that have changed since then. These trees that inhabit emotions and run a trail...the same one that is found on a page in

his notebook. He takes out this page, and thinks: “a replica? why do grandpa? “. At that very moment, he has no idea that these two cards are the key to a place he doesn’t know yet. By bringing the two elements together, César Foret plays with the rotations, he plays with the angles by superimposing the sheet of the notebook and says “Marie Antoinette! an intersection! This César is a taker, he goes! He comes across a barrier of trees and asks himself: “What are you hiding, grandfather, tell me”. He moves forward in spite of this density and discovers an open space where the grasses have created an important place for themselves by their height. César comes face to face with a module, a machine that he can hardly make out. Overgrown with plants, covered with dust, its appearance impresses him. He is seized with emotion.

The accomplishment of the drawings in the notebook is placed in front of him. This machine had become the habitat of birds, the shelter of invasive plants, the refuge of dust. César almost wept, moved by a machine he wanted to discover. As he enters, some old rollers lie on the floor, he raises his head and sees a dashboard, a control panel that dazzles him. On the same floor, he notices a print that confirms the presence of his grandfather, the drawing on the cover of the notebook. The same shapes, the same hollows, the same stops, the same traces. He hurries to insert the notebook into the ground. The movement is hard but turns counter-clockwise and a gear engages. It’s a trap door! Completely black, buried in the ground, “what is this place? “César murmurs. He takes the risk of going down the ladder, into this trapdoor, with the help of a lamp allowing him to light up the place. He is afraid because he doesn’t know what to expect. He is apprehensive. Facing the wall, a large painting canvas, a large work of art at the end of his nose. A newspaper on a rough wooden table covered with dust.

The story of a painting called the map of the world from above, the adventure Albert Foret had in flying over the countries of the world before the world war forced him to hide his flying machine and keep the secret that only a ‘Foret’ could discover. César is off on a very long journey again, but this time sitting in Albert Foret’s cellar. “Take me with you, Grandpa”.

L EN/FR

e récit d’un jeune artiste au nom de Foret, César Foret.

Tout démarre par la forte relation entre son grand-père et lui. Prénommé Albert Foret, celui-ci, aussi artiste peintre et héritier de père en fils d’une immense forêt qui était son espace de création et d’expression. Le grand-père avait une très grande affection pour son petit-fils et lui partagé son savoir et sa maitrise en lui apprenant le regard pour l’art et l’art du dessin lui-même. Le jeune César vécue son enfance parmi ses grands arbres et développa une joie de vivre et trouva son plaisir dans cette forêt qui était comme la sienne aussi.

Le temps passe et le jeune homme se vit séparé de l’endroit dans lequel il a vécu et grandit aux cotes d’une pour lequel il portait une grande estime. Le déménagement d’un univers à un autre qui restera ancré dans la mémoire de ce dernier. César quitte la forêt et surtout quitte son model, son grand-père. Albert fait cadeau à son petit-fils, qui pour lui a une énorme valeur mais César trop jeune pour comprendre prit ce carnet comme un souvenir qu’il apprendra à découvrir bien plus tard dans sa vie. L’écart se creuse et le temps passe. Les années passent et la vie suit son cours quand César, devenue adulte apprend que l’homme qui avait façonné son enfance a quitté ce monde. Il replonge constamment dans des souvenirs avec son grand-père qu’il n’a jamais effacé de sa vie. La seule chose qu’emporte César est un carnet de croquis de son grand-père qui vit au fond de sa mémoire. Il retrouve ce carnet enfuit quelque part et décide de l’emporter avec lui lors de son voyage retour à la forêt. Après tout ce temps, il redécouvre le contenue du carnet qui éveille en lui des sentiments de nostalgie.

Il recommence à le feuilleter sans arrêt et s’arrête sur un dessin de son grand-père parmi un groupe de gens dans sa forêt. Ils sont tous debout devant une végétation que César reconnait toute suite.

Il aperçoit une partie gribouillée en arrière-plan de ces derniers.

En rapprochant son regard, il remarque comme un objet abstrait à cet instant mais qui a une grande similitude avec les croquis des pages précédentes du carnet. Jusqu’à présent, il n’avait pas fait attention aux détails du contenue du carnet. Ces arbres reconnus sur le dessin lui rappellent ses passages dans la forêt qu’il a envie de retrouver une fois arrivé. Sur place, il refait les pas de son enfance qui l’entraine, qui l’emmène, c’est son domaine.

Il aperçoit cette image que sa mémoire fait surgir et rappel ses histoires que lui racontait son exemplaire. Tout cela lui conduit vers ces arbres qui ont changés depuis. Ces arbres qui habitent des émotions et qui enfuit un tracé…le même qui se retrouve

dans une page de son carnet. Il sort cette page, et se dit : « une réplique ? pourquoi faire grand-père ? ». A ce moment précis, il ne se doute pas que ces deux cartes sont la clé d’un endroit qu’il ignore encore. En rapprochant les deux éléments, César Foret, s’amuse avec les rotations, il joue avec les angles en superposant la feuille du carnet et dit « Marie Antoinette ! une intersection !

Il est preneur ce César, il y va ! Il tombe sur une barrière d’arbres et se demande : « que cache tu grand-père, dis-le-moi ». Il avance malgré et passe parmi cette densité et découvre un espace dégagé où les herbes se sont créés une place importante par leur hauteur. César arrive nez-à-nez à un module, une machine qu’il arrive difficilement à distinguer. Envahis de plantes, recouverte de poussière, son allure l’impressionne. Il est saisi d’émotions.

L’accomplissement des dessins du carnet se placé en face de lui. Cette machine était devenue l’habitat des oiseaux, l’abris de plantes envahissantes, le refuge de poussières. César en pleure presque, émue devant une machine qu’il a envie de découvrir.

En entrant, des vieux rouleaux traine au sol, il relève la tête et vois un tableau de bord, un poste de commande qui l’éblouie.

Sur ce même sol, il remarque cette emprunte qui lui confirme la présence de son grand-père, c’est le dessin se trouvant sur la couverture du carnet. Les mêmes formes, les mêmes creux, les mêmes arrêts, les mêmes traces. Il se hâte d’insérer ce carnet dans le sol. Le mouvement est dure mais des tours dans le sens inverse de la montre entraine l’enclanchement d’un engrenage.

C’est une trappe ! Complètement noire, enfuit dans le sol, « qu’est-ce que cet endroit ? » souffle César. Il prend le risque de descendre par l’échelle, dans cette trappe à l’aide d’une lampe lui permettant d’éclairer le lieu. La peur lui gagne car il ne sait pas à quoi s’attendre. Il appréhende. Face au mur, une grande toile de peinture, une œuvre de grande envergure au bout du nez. Un journal posé sur un table en bois brute recouverte de poussière.

L’histoire d’un tableau appelé la carte du monde vue d’en haut, l’aventure qu’a vécu Albert Foret en survolant les pays du monde avant que la guerre mondiale l’entrainât à dissimuler sa machine volante et lui força à garder ce secret que seul un ‘Foret’ peut découvrir. César est repartie pour un très long voyage mais cette fois assis depuis la cave d’Albert Foret. « Emmène-moi grandpère »

In our project, the intention is to be sustainable. In order to achieve this goal, we have worked on several aspects.

According to LEED “wastewater management”, the objective is to reduce water waste and encourage water reuse. In our habitat, we have created a system to reuse both grey water and rainwater. This will allow the habitat to be more independent.

According to LEED “building reuse” the challenge is to reduce waste and environmental damage related to the manufacture and transportation of materials. In our project the habitat is dismountable, transportable, reusable and the construction last only one day.

Therefore, we do not destroy the environment with machines and materials deposited in nature.

According to the LEED “reduced parking footprint” the objective is to minimize environmental nuisance, less dependence on the automobile, less land consumption, less rainwater runoff. In our project, we have relocated the parking lot so that the site is not disturbed by environmental nuisances, to be independent from the automobile and finally not to destroy the natural landscape of the site by vehicles.

Dans notre projet, nous voudrions que « la cachette » soit durable. Afin d’atteindre cet objectif nous avons travaillé sur plusieurs aspects.

Selon le LEED « wastewater management », l’objectif est de réduire les déchets d’eau et encourager la réutilisation de l’eau. Dans notre habitat, nous avons créé un système permettant de réutiliser l’eau grise mais aussi l’eau de pluie. Cela permettra à l’habitat d’être plus indépendant.

Selon le LEED « building reuse » l’enjeux est de réduire les déchets et les dommages environnementaux liés à la fabrication et au transport des matériaux. Dans notre projet l’habitat est démontable, transportable, réutilisable et la construction ne dure qu’un seul jour. Par conséquent, nous ne détruisons pas l’environnement avec des machines et des matériaux déposés dans la nature.

Selon le LEED « reduced parking footprint » l’objectif minimiser les nuisances environnementales, moins de dépendance à l’égard de l’automobile, moins de consommation de terres, moins de ruissellement des eaux de pluie. Dans notre projet, nous avons relocalisé le parking pour que le site ne soit pas dérangé par les nuisances environnementales, d’être indépendant à l’égard de l’automobile et enfin ne pas détruire le paysage naturel du site par des véhicules.
