The need for disaster response management in an area gives full attention to the government to issue regulations and policies on the arrangement of land use and buildings against disasters. Indonesia, whose territory is surrounded by water, requires handling, especially for coastal areas that are at risk of potensial disasters. In general,the coastal area is the place for fishermen to live, which gives the spatial character of the area in the arrangement of a building model and its environment. The need for a place to live forms a group of settlements that make the coastal area dense and land less. The magnitude of the influence of the sea on the their livelihoods as fishermen forces them to settle in the area. The purpose of this study is to analyze the spatial planning model for the coastal area by looking at the sustability of the building layout and environment planning for disaster preparedness and then developing the right model for structuring buildings and their environmental in coastal areas in Majene district. This research uses aqualitative descriptive method that reveals facts in the field and then analyses it with literature studies from various related sources. The main target is a model of building arrangement and its environmental layout in coastal areas with variable indicators including land use and shape, spatial patterns and building mass arrangement, orientation and building patterns, circulation and access, community socio-culture and potential disasters which will be analyzed and then develop models that right for the arrangement of the building and its environment. This group is divide accourding to several zones then analyzed and presented with tabulated presentation. The sampling technique is based on division of zones arranged by referring to the image map of the area which is the object of research. The results of this research are in the form of planning a building arrangement model and environment in coastal areas and developing a model of buildings arrangement and disaster responsive environment. This research is expected to be a recommendation for the implementation or direction of government policieson the arrragement of coastal spatial areas in general and especially in Majene,West Sulawesi.
