Being the elements of architectural form, space, mass and surface vary inaccordance with the availability of structure and material. For this reason itis possible to state that the material Is a means of architectural expression.Morphological and qualitative chages in the outer forms of a material char-acterize the social and cultural efforts and the technical standards of the day,or period. Until the 19th Century old masters and architects who used to work with a limited number of material and traditional construction techniques, whileliving very close to the natural materials, knew the visual characteristicsof the materials like texture and colour, and in the light of intuitive as em-pirical knowledge, constructed the buildings.In regard to architecture, Industrial Revuluation has created changes in therelationship between industrial construction materials and constructionsector. In an age of mass production it can be stated that in terms of today's architecture, the observation of many of the informative and decisive ruleswhich make themselves apparent in nature, is being ignored and the respon-sibility of the architect has usually been shifted to the solution of the tech-nical problems. However, the industries which have produced textured andcoloured materials have been playing an essential role in the solution of thevisual apperance of our environment. For this reason the recognition of ma-terials by the architects and the designers must not only express the factthat the architects and the designers only know about the technical proper-ties and internal structure of the materials. While the architects who useform and material as a means of architectural expression, are selecting thematerial-the selection should be true to the nature of the material and makethe use of the material possible exactly in suitable situations-they shoulddevice on matters of designing by knowing aesthetic and plastic values of amaterial like texture and colour and keeping in mind that the material is ef-fective in perceiving space, mass and surface. Moreover, in'recent years theuse of traditional materials has become actual as a consequence of people be-ing conscious of the values of the traditional architecture which is composedof traditional materials, and environmental data. From this point of view, being the most important traditional materialswhich form the traditional space, wood and stone will be studied in terms oftextural properties. In order to introduce the research with examples, theArchitecture In the Eastern Black Sea Region in which wood tohgether withstone have been used perfecty will be handled as and example and comparedwith the research results obtained in the Faculty of Architecture at YildizUniversity and retatedlb the textures which are preferred in both inner adnouter spaces.In this declaration after the textural properties and expressions of wood andstone are examined respectively, the textural effects appearing because ofthe fact that these materials are used together to form a surface will bestudied.Then the place of surface effect in the texture of nature and the relationshipsin terms of landscape values will be expressed by exemplifying with the useof slides. In the last part of this declaration the relation of the visual effects of sur-face with texture and the relationship between colour and texture will bedetermined and the place of the textural effect of the traditional materialwhich develops spontaneously in our traditional architecture will be em-phasized and the areas of usage of the traditional material in today's archi-tecture will be investigated.
