The impact of interior design in the success of the content of architecture spaces, internal and external - Case Study: "Separate residential buildings (villas) in Nablus, as a model"

Architectural Spaces' Study containing the elements, principles and determinants is considered as one of the most important Architectural studies especially modern ones since it's a study which patterns the human in an attempt to form intelligible language between the human and surroundings or the space where he dwells. Architectural Space in its physical form, functional form and aesthetic appearance is a container in which humans interact to form civilization which is considered as the highest and finest one created by humanity. Accordingly, this study was where it has tried in its first chapter to search the depths of Interior design to define its concept, show how did the researchers and specialists define Architectural Spaces, define its concept, principles, a range of correlations between its internal and external parts, so the study has shed light on the philosophical bases and the dialectics of internal space design, thus it posited the organizational psychological principles such as balance, order, sequence, measurement, relation, the principle of unity and other. Then, it focused on Exterior architectural space in terms of location, influential environment, exterior form of the building and standards of its relationship with its surroundings as Lighting, ventilation, privacy, views and other. This study has followed a descriptive approach in its theoretical framework to identify the interior architecture, so it gave a brief history about the development of this science.Then, it discussed in brief details the requirements of interior design. It was offered to the schools which it divided into: functional, structural, aesthetic and humanitarian requirements. But regardless of the type of those requirements, there are influential forces in the structure of the interior design which core is the human in his personal and social formation, his culture and all sources of his cognition and traditions. Then, the study shifted to talk about residence, its importance and types. It elaborated the elements of separate housing units since it's the practical side in the study as entrance area, architectural spaces such as living room, bedroom, services and others. It talked about principles of design of that elements or spaces such as space, standards, guidance, location, lighting, colors, and correlations or inter-relations. As the recent studies support saying that colors' science, lighting, used raw materials, method of their use, decorative supplements such as furniture, curtains, paintings and others in interior design have deep impact upon the psychological and behavioral life on the side of individual and society. This study addressed these topics and strengthened their theoretical side with describing and explanatory image. It indicated ways of use and coordination with the aim of harmony and integration to impart the desired aesthetic form and reanimate a sense of calm and psychological comfort. In the third chapter, the study talked bout process of design and its four pillars: the designer, user, law and building. It talked about the importance of having a participatory relationship between the designer, user and owner during the period of design or implementation. It resorted to consider the user as a secondary designer and involve him in decision-making of design without excess or negligence in order to reach a project with complete corners with regard to architectural purpose, functional form and aesthetic value which enhance the confidence of the designer and gain the approval of the owner or his satisfaction. The study followed the descriptive approach in its applied framework through conducting interviews to identify the views of a sample of owners of separate housing units (villas) in engineers' housing in Al-Jnaid area. The interview covered a third of the population of the housing which includes fifty-five used housing units i.e. inhabited and nineteen unused units. The interview has included two types of questions: Type one talked about the user's opinion (dweller) about interior design, its importance and his personal experience in it in terms of his collaboration with Interior designer or not, the consequences accordingly, his opinion about the performance of the interior designer, his experience with the interior designer in general and the mechanisms used in the implementation. While the second type of questions has a professional and more specialized nature. The questions included questions about the architectural spaces such as the external shape of the building, interior design, proportions of the building, surrounding gardens, architectural spaces, lighting, ventilation and other. The researcher allowed the user to express his answer in terms of the level of satisfaction as: excellent or good or intermediate or weak where the extent is left at the end for the user to make suggestions and recommendations for similar housings in the future. This study emphasized the importance of ongoing assessment processes, making use of them and keeping up the developments and new technologies The study concluded with a number of most notably results: an emphasis on the importance of interior design in enhancing and enriching architectural space including the results for the user at both physical and psychological levels. Based on these results, this study called -as a recommendation - for the need of interaction between the designer and user during the process of interior design or in the implementation phase in order to get comfortable dwelling which keeps pace with the times and the recent developments, has identity and address which is in line with the spirit of the place and brings authenticity and urban belonging.
