Classification of typical layout design for Indonesian apartment buildings

Abstract

Along with rapid urbanization, housing development increased in major cities worldwide. Public and private apartments have been constructed rapidly in Indonesia to accelerate housing provision, particularly in urbanized areas of major cities. From the early era of apartment construction to the present, many design prototypes have been implemented for various specific purposes such as energy-saving. Nevertheless, no comprehensive study has determined a typical layout of apartment buildings in Indonesia. The typical layout design is useful as the base model for building simulations. This study sought to classify the typical layout design of public and private apartments in Indonesia, using the selected building drawing data ranging from 1986 to 2021. We obtained primary data consisting of 268 public apartments from 22 cities and 268 private apartments from 9 major cities in Indonesia. To determine the typical layouts, both qualitative and quantitative analyses were conducted. As a result of this study, a pair of typical public and private apartment buildings which include the 1-bedroom unit and 2-bedroom unit types have been selected as the typical layout of the Indonesian apartment building. The results of the typical layout classification could be utilized as a standard testing model for designing future apartment building prototypes.
