In the 1970s Universal Design began considering to the needs of the wider population as a responsive design method. As well, in the field of architecture and creating space, vernacular architecture as an architecture type came out human needs and as response to architects not considering people’s life necessities. For the reason of technology this kind of architecture is forgotten. This article is comparing the level of compatibility between vernacular architecture and the theory of universal design by surveying in the concept of this two approaches. Also, it looks at the two main questions: Which principles of universal design can be used in new vernacular architecture? and which criteria of vernacular architecture are more effective on inclusivity of space? As a first step an extraction of universal design criteria and vernacular architecture was undertaken through a literature review. Then the whole of factors were summarized, via factor analysis methods. The third step is defining the relation between factors and the hypothesis. Examples of houses in Tehran’s historic centre that have national heritage registration will be discussed. Using statistical modelling software the social aspects of the houses was interpreted and it seems the hierarchy and spatial coherence in vernacular houses has a more positive effect on the inclusivity of spaces.
