Study (investigation – analysis) and construction of repetitive solid plastic elements with the possibility of multiple combinations between them, in order to produce functional Plastic arrangements in the architectural space. Phase 1: a) Selection and accurate design based on photographs, sketches, drawings, of the architectural space (interior or exterior) in which the requested plastic arrangements will be developed and implemented using the above elements. (b) Sketches, drawings and design models for the investigation of one or two Plastic Elements , which will be derived from regular or non, geometric solids or from the development of free structures and forms derived from the natural world. In relation to the function – form relationship of the elements, the possibility of their reproduction is studied so that by combining with each other appropriately (without the necessity of using binding materials in the inter-connections – combinations of the plastic elements during the final presentation of the various proposals of the construction) they produce visually interesting plastic – functional arrangements in the selected Architectural space. Phase 2 a) Construction in various materials (solid or fluid), of a certain number of copies of the elements at the appropriate scale (from 1:1 to 1:20) b) Presentation on boards, sketches-drawings, photographs of all the above phases, with study and design of examples of the final proposal for the integration of the overall plastic construction in the specific architectural space with various representational / visualization methods
