Il nous faut de nouveaux architectes, de nouveaux constructeurs pour créer une nouvelle société.
Sa structure doit être bâtie sur de nouvelles fondations, sur des faits et des valeurs nouvellement découverts.
De tels architectes n’existent pas encore.
Il n’y a pas de bâtisseurs, d’hommes qui, observant le monde et étant conscients du fait que sa structure s’écroule, se transforment eux-mêmes en architectes.
Là est notre problème : nous voyons la société se défaire, se désintégrer, et c’est nous ‹vous et moi‹ qui devons être des architectes.
Vous et moi devons redécouvrir des valeurs et construire sur des fondations durables, fondamentales ; car si nous nous adressions à des constructeurs professionnels, à des bâtisseurs politiques et religieux, nous serions très exactement dans la même situation qu’au départ.
C’est parce que vous et moi ne sommes pas créatifs que nous avons réduit la société à ce chaos. Et maintenant, le problème est urgent, aussi est-il indispensable que vous et moi soyons créatifs, que nous soyons conscients des causes de cet écroulement et que nous érigions une nouvelle structure, basée non sur l’imitation mais sur notre compréhension créatrice.

Photos du site par grand beau temps ...froid !
facétie de la publication d'article, on commence par 3 photos qui montrent la vue côté Sud .....
et la possible extension ....
puis, la vue (depuis la pointe est) sur l'ancienne ferme et le couvent des Dominicaines, en contrebas
et le Centre de Dinant tout dans le fond
et puis, enfin, quelques vues côté Ouest et Nord
ou l'on voit la haie qui "isole" le terrain et de l'environnement périurbain
voici la végétation qui cache horrible palissade en béton qui matérialise la limite avec l'ex- terrain des Petites Soeurs (coté Sud)
et voici quelques vues des habitants actuels....
revoici la haie de séparation côté "ville"
et voici une des "buttes" très fréquentes partout...
et voici ce qu'on voit du point le plus haut du terrain en regardant dans la direction de la Gare
vue (vers Dinant) depuis la borne haute de la "cloture sud"
vue vers la rive droite de la Meuse
et voilà la vue côté Nord avec la cloture avec le terrain cultivé qui marque le début de l'immense zone agricole du plateau de Neffe
je suis au point le plus haut du terrain
et tjs le champ de bosses....

Exemple de serre de maraîchage chauffée par un tas de compost
Composting Greenhouse with Straw Bale Foundation
Our household of 2 adults and three children obtained all our household hot water from a composting greenhouse we constructed in Portland, Oregon in 1994. It provided hot water at a temperature of 90-130 degrees (Fahrenheit) continuously until it was dismantled 18 months later. We used the space to grow several species of mushrooms and to house plants from our garden during winter.
The greenhouse design was similar to inexpensive "tube" greenhouses. Outer dimensions were 16x30 feet. The foundation walls consisted of 3 courses of rye grass straw bales pinned together with 1/2 inch steel rebar. Bale size was 2 feet x 2 feet x 4 feet, giving two-foot thick walls along the base. Therefore inner dimensions were 12 feet wide by 26 feet long. Bales were stacked like bricks, as is typical of straw bale construction. A layer of 3 mil plastic film surrounded the bottom bales, separating the straw from a layer of wood chips on which the bales rested and the compost which filled the greenhouse about three feet deep inside (except for a 5 feet by 12 feet entry at one end). The roof consisted of 6 mil ultraviolet resistant plastic film supported on 20 foot arches of rebar spaced every 2 feet along the length of the structure. These arches were held rigidly into a 2 feet x 2 feet matrix with horizontal rebar spaced every 2 feet running the length of the structure. The straw bales on the sides and end walls were also covered with the same plastic film as the roof with a door framed out of lumber at one end. A single sheet of 32 feet wide by 32 feet long plastic covered the roof.
Two PVC 3/4 inch water lines ran underground from the house to the greenhouse. The cold water supply originated at the washer hookup cold line. Hot water returned from the greenhouse in an insulated line after circulating in the hot compost and entered the house plumbing at the washer hot water hookup. Therefore no modifications to the original house plumbing system were required. While the greenhouse heater was operative, the original hot water heater was turned off and its intake valve closed. Heat exchange occurred in the compost in which was embedded one hundred feet of coiled 1.5 inch internal diameter plastic hose. Compost mass totaled 3 feet deep, 12 feet wide, and 21 feet long, or approximately 28 cubic yards. It required replenishing several times during its lifetime because of continual slow decomposition.
The total amount of hot water contained in the hose inside the compost (comprising a cylinder 100 feet long by 1.5 inch diameter) was 9.17 gallons. This (when mixed with appropriate cold water) was an adequate volume to take 3 quick showers without running out of hot water.
The compost biomass consisted of wood chips and other ground tree material run through a chipping machine. This material is delivered to our site free of charge from many tree service companies. We supplemented this primarily high-carbon matter with high-nitrogen matter from household waste such as garden debris, kitchen compost, and waterless toilet.
-->manures. Eventually, when the greenhouse was dismantled to reclaim our back yard as a garden area, we had enough finish compost to cover our entire yard 8 inches deep. Needless to say, we have a fabulous garden from this new soil fertility. Further details and a proposed simpler
version of compost heater is discussed in a report I wrote
for Guatemala Peace Corps volunteers. -->

Extrait cadastral du terrain sur les hauteurs de Dinant
Echelle 1/2000
+/- 60 ares de terres agricoles (praires en friches depuis plusieurs années, n'ayant jamais connu le mondre engrais ou produit chimique) enclavées dans une zone à vocation forestière
à moins d'un km de la Gare tout en bénéfiant d'un calme, d'une vue, et d'un environnement étonnants ....
