Τhe village of Kallio and the artificial lake of Mornos, constitute the foundation of this thesis’ subject. The topos in which these coexist, is being approached in the context of an aquatic ecosystem - with this meaning, taking into consideration its needs, its dynamic elements and the changes which these bring into the landscape, within time. The village Kallio, inside the reservoir’s waters, is being deconstructed on its own natural pace, It is part of the lakebed’s morphology and it indicates the anthropogenic character of the landscape. While studying the place, effort was made on reading the elements of the landscape - those sediments that form narrations - which tell the story of what happened but also of what is happening now, in this changing field. The practices that are proposed for the supporting of the aquatic biotic and a biotic world, in combination with offering a path to the visitor of the lake, are attempting to develop symbiotic relations, promote a beginning of coexistence through the design, and maybe a dialogue, between human and non-human organisms in the area.
