Space planning decisions for the residential buildings of mass series after reconstruction for extended families and family groups of Central Asia (on the example of Tajikistan)
The current need for additional domestic accommodation has necessitated the formation of new housing types for different categories of families in terms of affordability and market requirements. In particular, the demand for apartments can be met by the renovation of Soviet pre-cast concrete residential blocks. Firstly, there is a need to quantify the growth of the elderly population and the ever-increasing desire to preserve friendly relations between the generations based on Tajik tradition. Secondly, there is a need to design special residential units intended for the resettlement of extended families, family groups and families consisting of several generations. The renovation of the old Soviet buildings will reduce not only the physical deterioration of a building by complete or partial replacement of individual structures, but will also eliminate obsolescence as a result of internal redesign and enhancement of a building. An analysis of the space-planning and structure of a residential building will establish the degree of obsolescence, as well as address the question of reconstruction as a dwelling for extended families through the partial redevelopment of apartments. Such redevelopment would increase the area of common rooms to include insulated terraces and loggias, the removal of some partitions and the conservation of existing sanitary cells. This article deals with the reconstruction of large apartment buildings based on Soviet mass-produced residential block series TTZH 1-464-AC-3, which is dwelling for extended families consisting of several generations. The article proposes 4 different options for redevelopment. These options will increase the living space of the reconstructed residential building from 25 to 35 %, and will increase the population density in all dwellings by 50 %. The intention is to improve space-planning of mass-produced residential blocks, series TTZH 1-464-AC-3, in order to match the demographic characteristics of Tajikistan for extended families and family groups.
