Density is a critical typology in determining sustainable urban built-form patterns. Built-form refers to the assemblage and arrangement of the building masses in a city reflecting the spatial layout of spaces. The relationship between density and urban character is also based on at certain densities (thresholds). In a wider sense, sustainable cities are a matter of density. Recent debates about the creation of more sustainable urban form, compact cities have led to a renewed focus on issues of density. The argument is that high density high-rise with low ground coverage or compact city form can offer a high quality of life while minimizing crime, possibility to provide adequate amenities, green and open spaces, accessibility and space consumption. However, the relationships of density and patterns built-form are not reasonably well developed and integrated into the urban design-planning processes in developing countries cities like Addis Ababa. On the hand, not many studies have been undertaken with regard to density in relation to patterns of built-forms. Therefore, this study aims to explore density in relation to patterns of built-form in the process of planning & design of urban spaces2. The analysis is based on the primary sources as well as secondary documents collected from the concerned agencies and related references. The findings illustrate that high density high-rise with low ground coverage patterns of built-forms can offer better possibilities for installing good spatial quality3 of urban spaces. It concludes with an overview of emerging thinking/implications where further efforts are required in the future

Technology affected human life in many ways in different eras of mankind history. Today, the information and telecommunication technology has revolutionized basic structures of human life. Changes are from the whole to the parts and vice versa, which include family and society too. Family lost its former structure in the information age and differentiated from patriarchy family. Societies have been formed based on logic of networking and new network societies are predominant form of our societies with their advantages and flaws comparing with the traditional societies. Basic concepts of the life i.e. space and time also have been transformed and living in space of flows and concurrency of functions require a special structure or body. Architecture constitutes the body of our societies which must meet physical and mental needs of humankind. In a transforming world, architecture is connecting ring between society and surrounding environment, previous traditions and future world, which its borders between reality and virtuality are very close. Architecture with a global-local approach can assist human who is wondering in the virtual world to redefine its own identity and finds its position in labyrinth of global networks and also safeguards his survival via respecting nature and paying attention to sense of place as one of the principles of vernacular and traditional architecture. Technology has affected on the architectural design, leading to creation of new shapes and distinct erections. Architectural design by employing networks and collective intelligence, overcome temporal and spatial limits and became a collective activity. Architecture by creating spaces according to global, regional and local considerations and emphasis on principles of design supported by collective intelligence and strengthening bonds among the human, nature and technology, will act as a panacea which will heal crisis of identity and cultural multitude; the crisis that storm out human body and soul in our present stressful world.

Urban spaces are the heart of any city. These spaces play a crucial role in improving citizens' quality of life, welfare, and mental health. In recent decades, there have been growing concerns among urban experts over the widespread disregard for public spaces due to the dominance of capitalism and changes in citizens' lifes tyles due to their crucial needs being ignored. Despite the considerable efforts to develop urban spaces in Iranian cities, there are s till huge gaps between proposed plans and implementation processes. Due to limited resources and execution mechanisms, it is necessary to identify such spaces based on real-world needs and prioritize them in the implementation phase. In line with this, the present s tudy seeks to develop an efficient method for identifying potential public spaces in deteriorated urban neighborhoods through participative processes, reducing the cos ts and time of projects, and increasing the effectiveness of projects employing the urban acupuncture approach. The data collection and analysis tools used in this s tudy include semi-s tructured interviews, focus group discussions, analysis of documents related to the development of the neighborhood under s tudy, space syntax analysis using Depth Map software, prioritization of indicators using AHP ques tionnaire and analyzing them in Expert Choice software, and analysis and overlaying information in ArcGIS software. The findings related to the Pamenar neighborhood in Tehran sugges t that it is practically possible to identify and prioritize the public spaces through the urban acupuncture approach by s tudying and analyzing motion flows. Finally, 13 urban spaces have been identified and prioritized in the neighborhood.
