The present thesis work negotiates proposals for the preservation and promotion of an abandoned fertilizer industry in Ptolemaida, Greece, with the name AEVAL. The area and its buildings remain unused since its closure. The work complements and reconstitutes a Museum Zone proposal for the region, bringing the human scale and interventions closer to existing industrial shells. There has been a problematic concern how to convert shells which have not designed for human activity and expropriate them. The understanding of the vast scale was performed in the first stage with a series of diagrammatic sections and coverage area of existing shells. The lack of drawings in digital form for the topographic map but also for the imprinting of the buildings itself led to the imprinting by the method of photogrammetry or 3d scanning of the area. A series of aerial photographs created a surface and then, with appropriate treatment, reflected the study area. The produced topographic map revealed aspects of the land unreadable by other digital methods.
Subsequently, a close observation was made, photographically and with gypsum replicas of the shells, which are signs of abandonment, however they expound opportunities for design movements. The replicas were supplemented with materials that reveal the interference of nature, the morphological effect on a cast material, while they were digitally recorded by photogrammetry. They are all research in the field of negative spaces, the degree in which a form influences, when it is removed or perceived, the final morphology. The findings resulted in a museum-wide intervention, surpassing the scale of the city to attract visitors from different areas. Apparently it excludes from a standard museum organization plan, adding symbolic state on intervention to enhance the personal experience of the visitor.
Procedures are listed on three levels that works supplementary and as a whole. Underneath the surface an organized museum path is developed along a corridor, main axis, which crosses the area. Oppose to it four exhibitions about the regions past and its industrial character successively unfold, before leading gradually to the surface. The exhibitions are dedicated to lignite rocks, industrial components and engines fund in the area, paleontology and the water, as a route of all rocky and industrial heritage. Functional designated spaces end up symbolic, becoming a comment on the deterioration brought by industrialization in the city of Ptolemaida.
The case of an underground structure is to maintain the industrial character of the area at ground level but also to offer a different path, which is called “monumental”, of history and memory. Surface openings are limited only to points deemed necessary for organizational and operational reasons in the ground plan. Perception of a basement can be seen from the two towers at the entrance and exit, but also from two large patios that accompany them. The corridor in successive points is highlighted with large openings but leaving the surface of the ground as a touring square to the other activities of the museum area.
At the end of the shaft, a shed with earthen footprint acts as an observation point.Visitors create their own view, as the platform does not include a specific visual framing. The morphology of the roof is emerged with soil, giving an almost irregular relief. The concrete slab is poured on a dirt bench, taking both the negative footprint and the irregular morphology of the soil. Model is initially developed and then drawings are produced with photogrammetry method. The final result of the construction is not strictly predetermined. The construction - production method is defined. The observatory also serves as an interconnection square with the ground level interventions, accommodating semi-outdoor events.
Three industrial shells are maintained and receive operational uses. Managed as monumental sites,a cranebridge and two morphologically different cooling towers invite the visitor to inner observation.The program also includes the programmatic preservation of six other industrial shells as monuments coexisting with the surface axis of motion. An outline of sitting structures areas, following the archaeological cannabis, symbolizes the existence of a total intervention in places that the observer can visit independently and separately. A walking route on the surface of the pipes works similarly, leaving the visitor the chance for creating his own views of the sight from above, complementing his overall experience for the area.
