Transformation of National Housing’s Layout Design in PERUMNAS Sarijadi Bandung

Abstract

PERUMNAS (“Perumahan Nasional”/National Housing) was established in 1974 to provide decent housing for the lower middle class in Indonesia by the government. One of their projects was done in Sarijadi area, Bandung in 1976-1978. The typical PERUMNAS house in Sarijadi was based on Type 36, named after the building area which was around 36 m2. As time changed, the people’s needs, and behaviour also evolved, and it also affected the contemporary PERUMNAS layout. As such, Type 36 house may be evolved into a growing house, in a sense that it is able to be developed, usually vertically, by stages based on standard housing minimum cost to accommodate the evolving needs of the occupants. This paper will analyse one such growing type 36 PERUMNAS house case, which is located in PERUMNAS Sarijadi, Bandung, West Java. The house was initially built in 1976-1978, and several renovations were done in 1994, 2007, and 2017 as the family grew. By observing the layout transformation, the results showed that the occupants adapted to the original layout by developing the building vertically to add private areas and utilizing the front and the backyard to make new service areas. In the future, homeowners can adapt to shifts in activity by carrying out sustainable transformations in the form of additional functions which then result in different zoning.
