The aim of this study is to develop and preserve the identity of vernacular architecture in ecotourism sectors in Nubia, Egypt so that they could develop the economy and urban texture as well, and to outline the role of natural and cultural Egyptian rural communities to protect and preserve their heritage and their ecotourism resources as well.

The research main findings based on the performance of selected vernacular-ecotourism case studies in Nubia, Egypt, were the criteria of vernacular ecotourism preservation. The research will accentuate that the Nubian building technology could be useful for redesign ecotourism resorts in rural community in Egypt. Sustainable architecture planning is a capable apparatus for making ecotourism offices that encourage aware and widening social exchanges.
