**6. Implicit finding: adaptive sustainable housing**

Adaptive housing features in cultured communities are evident in the reflective appearances of transformed dwellings layouts. The underlying determinants imply that users' prioritise the ability to perform activity more than the host space. As such, dwelling spaces are valued based on their ability to accommodate inhabitants' activities. Usually, these stems from users' acquired experiences with space through transactions over a period of time. It usually reshapes urban housing architecture through the influence of cultural order. Invariably, it shows a synthesised model that combines root values and modern design ideals making the product-culture responsive housing design.

Consistently, features of the overall emerging pattern reflect housing procedure that is grounded on evidences from users' experiences and initiatives achieved during transformation of dwellings. Together, they form the critical features required for sustainable housing. Spaces in dwellings are gauged by their ability to accommodate multiple functions. These functions are most times repetitive and are time based. Socially dwelling spaces are inclined to gender, age range, and privacy level. Irrespective of the technological influence, spaces are ordered and arranged with family structure in consideration. Usually, household's lifecycle shows changes in family structure, which provides the need for transformation.

Meanwhile, the arrangement includes a core and a flexible main that usually evolve overtime in phases from the core. The core is the initial configuration at occupation, while the flexible main are additions and adjustments made to accommodate changing family structure. This conforms that houses that grow with users' behavioural character shown in their transactions as the growth determinant is usually preferred in cultured communities. The climax of major transformation activities marks the apex of adaptive sustainability in the configuration of houses. These houses become a model for derivation of design indices and a research platform for regional and local sustainable houses.

Furthermore, features of adaptive sustainable housing blends with the mixed-use space concept of the space utilisation common with households in cultured communities. For example, it is not uncommon to have spaces such as study rooms, library, consulting rooms for doctors and lawyers, and studios for architects incorporated in their dwelling arrangements in modern houses. Similarly, shops are common spaces attached to residential buildings in most urban communities of developing countries [13] aimed at boosting the family income. In this regard, home-based businesses are on the increase in cities.

Beneficially, these features are usually derived from the evaluation of transformed houses and the basic space needs differ across regions and communities. Flexibility in space-use pattern remains consistent and enhances livelihood and inhabitants' liveability. In addition, tangible and intangible indoor and outdoor spaces are crucial in adaptive sustainable housing provision. Such houses are seen to be occupied for longer period with inhabitants developing a sense of place attachment and a choice to remain rather than change dwelling overtime.

The architectural paradigm presented in this chapter is targeted at creating the need for stakeholders to harness benefit of housing transformations, and then use it towards improving housing design and ensuring sustainability of emerging configurations. While implementation is expected to project adaptive sustainability principles in housing design, it will require further advancement of specific attributes and patterns peculiar to environments. In the long run, values are respected and integrated, while resources and expertise are introduced to standardise transformation benefits towards ensuring sustainable housing.

Housing transformation benefits have posed clear values of long history. The use of digitalised building culture to override the values of inhabitants in building production across cultured settlements is usually confronted with resistance. But rather efforts should be focused on innovatively reshaping the existing cultures towards opening greater possibilities. These would eliminate the perception of undermining local content, attachment to place despite environmental pervasiveness, factoring the inhabitants' lifestyle. Thus, several city dwellers that like to live a local lifestyle in a global world with dwellings that fit into their values are tolerated.
