Examining new structure notion and context relation in terms of uptodate practice in historic environment

Historical environments include precious structures which were defined as a `new? in the past but are defined as an `old? today. These structures bring all social, cultural, economic and technological data from its period. They also make us understand circumstances of its period and these structures help us to evaluate them with modern structures which meet the requirements of today?s world. In this perspective, new structures which are going to be constructed in historical environments should be designed by connecting with old structures, representing of modern day architecture and, also, meeting requirements of human.In this study, main objective is research old structures and analyze how they can be used in today?s world and can be relevant to modern structures.In section 1, the subject is explained by stating objective, content and method of study.In section 2, the cause of protecting historical environment and the factor of deterioration of historical environment is examined by stating definition of historical environment concept in a wide perspective.In section 3, under the title of formation of new structures in historical environment, existence of `old? and `new? concepts in architecture and how they integrated to today?s conditions is clarified. Definition of new structures in historical environments is examined in the light of modern architectural conception. In this sense, the criteria which new and annex buildings in historical environment should have in the stage of design is referred. Intervention types of constructing new buildings in historical environment, which are new structure in old environment, annexation, restoration and transformation of existing structure, is elucidated.In section 4, concept of place, space, environment and context in architecture and their relations is explained. While environment-context relation in intervention of historical environment is synthesized, terms of location, scale, texture, material, color, form, function, sustainability is elucidated. Besides main design forms of intervention (simile, respectful, contrast, imitation) is clarified, these structures is analyzed in a wider perspective.In section 5, Projects of new structure, annexation and restoration which were designed for historical environment from 2000, are chosen and analyzed by taking into consideration of design and intervention forms.
