The objective of my professional proposal is to investigate the specific field of the spatial construction's discipline and its relation with the phenomenological field. The construction is the structure of a thought capable to aboard the inherent themes of the architectural space, studying the logic and coherence of the project in depths. Inside of the operational logic I find the structural architecture as the capable order of giving the possibility of generating the architectonical space, it is a concept given in tectonic terms, it involves both: The problem related to weights, efforts and materials and the shapes and human requirements. Here is where I probably find some answers to the synthesis of the problem.In this structure I find the intervening factors which reach the equilibrium and the coherence of ones with the others… Italo Calvino said in Palomar “a wave can't be watched without taking into account the complex factors that form it and other factors equally complex that it provoques”… At this point is when our job is to mold the space. The major degree of coherence is obtained by requiring the major quantity of answers for every element that composes it. We get to the highest degree of synthesis only when one of these elements can solve more than one constituent problem. The questions determine the diverse possibilities to reach the goal during the process of the project and time is a fundamental factor for the experiments to take place. I also think that is necessary to objectify the process of thinking, that the operations must be fundamental materials and that according to its determinations they will produce different sensations and will have diverse qualities. Themes such as continuity / discontinuity; inner/ outer; transitions and variations are seen on the exercising project, emphasizing the tectonic problem, and stressing the problem of space strengths: gravity, weight relation/support, tensions, distensions, lightness, fluency. These spatial architectonic constructions also show the sensorial, psychological and phenomenological experiences, and its effects related to the emotions, conducts, representations, symbolic configurations and importances.
