Deliberation on Domestic Rural Building's materials

In the past, rural buildings were built with the limited natural materials which were found around the villages. But nowadays there are many choices available to be selected and used in the rural areas. This has occurred because of two important issues. First: production of many different kinds of natural and synthetic construction materials which have been provided these days, and second: the transportation developments which have caused the possibility of providing construction materials to any villages of the country. This circumstance has had two results. The first result permits the designer to choose any material. The second result provides the variety and unlimited kinds of construction materials in rural areas. These results both seem to be good and favorable, but there are other parallel issues to be taken into consideration. For example by using different kinds of materials on the facades of the buildings, the harmony and unity of rural landscape can be damaged. Some materials are not also consistent with the climate and natural conditions of the village and so on. To achieve the best result for using the new materials, it is necessary to increase their positive characteristics and advantages and find ways for reducing the problems and disadvantages. In this regard, the characteristics of different kinds of construction materials must be studied well and a comprehensive comparison to be done before choosing the best and suitable materials for the construction. In order to choose the suitable construction materials, some criteria are needed for assessment and comparison. The present article is intended to provide some explanations for this subject. It will introduce six criteria. 1- Harmony with the form of building, 2- Presenting appropriate meanings, 3- Harmony with the natural environment and the rural landscape, 4- Compatibility with the climatic circumstances, 5- Suitability with the structure, 6- Availability and reasonable price for purchasing the materials. The article will also mention about different ways of using materials for the exterior walls and their joints.
