The basic design concepts of the neo-traditional development (NTD) come from western countries. Little is done to localise these design concepts according to vernacular Middle Eastern urbanism. This paper attempts to link the historical studies to the urban form and the new design approaches based on the traditional urbanism of Iran. The organisation/area of neighbourhoods/neighbourhood units, the walking distances/structure of the neighbourhood unit centres (NUCs) are investigated. The case-study cities are Yazd and Kashan as examples of sustainable societies. The conclusions can be used in new Middle Eastern development plans with similar cultural/religious/climatic conditions as the centre of Iran.
