The key to the survival of a historical building is in its active mode and the spirit of dynamism in it. The dynamism of space is always an opportunity to create a stronger relationship between architecture and society, to organize sustainable urban development. Hence, in-between urban networks are highly important in reviving urban dynamism.
The purpose of this article is to recognize and analyze the areas affecting urban dynamism interacting with the concept of in-between space, with the solution of changing the land-use of sumptuous historical buildings based on neighborhood-based contemporization model and seeks to answer the question how intracity dynamism  is  defined as in-between space.
In order to achieve the objectives of the research, the process of analysis proceeds by selecting valuable historical buildings and how to change their land-use. This study aims to study the impact of changes in the land-use of selected buildings as an in-between space in urban dynamism by qualitative research of the indicators derived from the contemporization theory and has evaluated the effectiveness of metrics using the opinions of four groups of participants.
Several rehabilitated historical houses in Tehran were analyzed with TND approach and an emphasis on the neighborhood-based contemporization theory, then areas and strategies affecting urban dynamism resulting from land-use change were extracted, and finally, the most obvious effective characteristics in selected in-between buildings were introduced as urban communication network.

Aims: The strong relationship between place and society is evidence of the formation of sustainable social life in the urban space. The valuable houses, as part of modern heritage; and factories as part of the industrial heritage; are separated from their context. The main purpose of this research is to formulate a place-based development approach. According to the research hypothesis, there is a significant relationship between economic, structural, public and environmental factors.
Methods: In order to achieve the objectives of the research, the process of analysis has been organized with the method of logical reasoning and content-qualitative analysis of the texture of neighborhood centers. This study intends to study the effect of interface space on inner-city dynamism by qualitative studies of the indicators derived from the location-based development approach, using the opinions of participants to evaluate the effectiveness of effective metrics. Three neighborhoods have been studied, selected from among the historical and valuable neighborhoods of Hamedan.
Findings: Analysis of the interaction of elements left over from the past heritage of Hamedan, with emphasis on the theory of place-based development, showed that the reconnection of urban elements with each other is of special importance and is one of the most obvious effective features in intermediate spaces.
Conclusion: According to the place-based development approach, in the dimensions of the middle space, spatial arrangement and diversity of economic performance and socio-cultural infrastructure in the urban context of neighborhoods, have an increasing role in the vitality of neighborhoods and creating sustainable dynamism.
