Rapid migration of a large number of skilled and unskilled laborers to urban centers augmented the claim in housing and accommodation. To accommodate this number, many traditional residences are renovating day by day but without managing with any building code or recommended rules from the authorities. As the primary settlers are moving out and housing is engaged by people from outside, the traditional lifestyle is varying in the neighborhood and place attachment and personality might be interrogated. Dhaka, the capital city of Bangladesh, has long been observed as one of the fastest increasing cities and at present the city accommodates nearly 15 million inhabitants and 60 percent of this population is migrants (BBS, 2005).
7. Findings of spatial formation: transformation reflected in social action and neighborhood identity
The substantial variances in socio-economic, cultural, political and in climatic in Dhaka, a number of comparisons are present in their physical layout, as well as in the course of conversion of their domestic spaces in home background (Figure 2). In Dhaka renovation of the physical environment could not establish a substantial impact, as tenants are more worried to earn more money for existence than desire social communication with neighbors. In the traditional houses, courtyards are vital spaces for the daily events and interactions; however, while these spaces are used for evolving extra rooms for rental purpose, there is decay in the social actions (Figure 3). The later accumulation and transformation of dwellings in the old buildings made the living entirely inaccessible from each other and as a consequence, social communication has progressively diminished.

The city center also accommodated the middle-income dwellers and the colonials to inhabit these traditional houses, who could encompass themselves in economic activities using domestic spaces. The grade of variation and modification by the expatriate and their transformation and transformation of spaces into new functions shows the potentiality of the old-style houses.
Old dwellings in the traditional neighborhoods have gone through extensive modification and revolution mainly due to economic causes. Also in both cases, landlords transformed their old houses either into economic enterprises or to rental units. Accommodation became the main importance rather than the social contacts and the replacement of homogeneous people with a more heterogeneous was recognized. To highlight the prominence of physical forms, Erman (1997) pointed out that, neighborhoods comprising of multi-storey apartments are less consistent and have feebler sense of community than neighborhoods with single-family residences. This is also true for Dhaka, as it has been verified to a number of apartment buildings, which have been inspected. People are now getting used to the different lifestyle where social interactions, community contributions and social proceedings are now taking place in big community centers outside the neighborhoods. These features also specify the variations in the lifestyle of the residents of our modern age where not only the physical renovation but the social achievement also generated long term impression that is gradually lessening the neighborhood supplement and therefore identity.
