RESEARCH QUESTION
What are the potential social benefits of the diversifying high rise residential units’ design towards the society?
INTRODUCTION
In today’s urban development, high density and compact development has been significantly discussed to support the growth in population in the urban context. High rise residential developments, which is also called as vertical living, are strongly promoted in almost every governmental affordable housing planning policy to be set in context of city centre. The current market demands a sense of vibrancy and community in the mixed development that they live in (Bell, 2004). Almost 68% of all Malaysian, which is about 18 millions of Malaysian, have chosen to live in the towns and cities as it shows a relatively high developing of urbanisation in the developing country (Wan Nor Azriyati WAN ABD AZIZ, 2014). As the population growth in the urban context, the needs for more residential housing in the vertical form are desperately getting higher in order to support the change in the different life stages and the housing needs. Likewise, in Singapore, the needs of vertical form of residential housing has been rapidly increased along the growth in the population and the change of different life stages.

Hence, Malaysia government has drafted ACT 739 under the Law of Malaysia to set up a body of organisation called PR1MA, Perumahan Rakyat 1 Malaysia, to plan, develop, construct and maintain the high quality of affordable housing. On the other hand, Singapore government has established a public housing authority, which is called Housing & Development Board (HDB), to plan and develop the housing estates as well as to transform the town into more comfortable and living environment. There are various projects are being developed and constructed in the recent years, especially in suburban area and urban context.
Both of the established organisations have implemented the smart growth city principles. The rapid speed of growth of the ongoing urbanisation in both Malaysia and Singapore has created the opportunities to implement the smart growth city principles in most of the development to avoid the highly inefficient urban sprawl in the urban context. However, one of strategies of smart growth principles stated that a range of housing opportunities and choices should be created and implemented in the development to support the different life stages of community. Therefore, diversity of housing choices in the selected projects has offered greater opportunities to create a more vibrant types of community, meanwhile, it also supports various range of incomes in one development.
OBJECTIVES
This study aims to analyze the potential benefits of diversifying high rise residential unit design in urban affordable housing to the society.
LITERATURE REVIEW
What is Smart Growth?
Smart growth is defined as a development that supports economic growth, strong communities and environmental health. Smart growth development intended to create high quality of that makes the communities to achieve economically competitive, create business opportunities and strengthens the local tax base. In order to create and maintain great neighborhoods, the Smart Growth Network developed a set of 10 basic principles to guide smart growth strategies. (Anon., 2015)
Ten Principles of Smart Growth
1. Mix land uses2. Take advantage of compact design3. Create a range of housing opportunities and choices4. Create walkable neighborhoods5. Foster distinctive, attractive communities with a strong sense of place6. Preserve open space, farmland, natural beauty and critical environmental areas7. Strengthen and direct development towards existing communities8. Provide a variety of transportation choices9. Make development decisions predictable, fair and cost effective 10. Encourage community and stakeholder collaboration in development decisions.
By implementing the 3rd principle of Smart Growth, the development must provide a range of housing opportunities and choices to meet the community’s existing and future needs.
The provision of quality housing for families of all life stages and income levels is an integral part of the smart growth approaches. There are various reasons that cities should offer a diverse range of housing choices for local residents. By integrating the planning structures for single and multi-family in new residential development, the development itself can support a more diverse population. It also allows more equitable distribution of households of all income levels. Besides, it is leading to create a higher demand for community services and facilities such as malls, schools, health care, office and recreation facilities. Diversifying housing in vertical form has also provided more opportunities in the development that allows the residents to have choices in a small piece of land.
However, when the development focuses into one type of housing, it creates a number of potential issues. The development will manage to attract one type of resident, which does not achieve the goal of diverse population in term of age, income level, families and singles. Hence, this approach does not manage to create a sustainable community for the reason being that no single type of housing can serve the various demand of diverse household in today’s market. Furthermore, if the types of community are being separated and group by the aspects of income levels, the locals with low income will be forced to accommodate in the suburb area and, hence, the social problems will be increased when the community are being segregated.
What is Urban Affordable Housing?
The concept of urban affordable housing can be defined as the allocation for rental or instalment must not exceed 30% of the total household income in the urban context (B Bakhtyar, 2012). By that means, the unit of housing can only be affordable if the resident’s household spend within 30% of its income on the housing costs, including the utilities, for them to live in the urban context where the growth of economic is rapidly increasing.
What is PR1MA?
PR1MA was established as a government owned company under PR1MA Act 2012 and under the supervision of Ministry of Housing and Local Government. It is established to help the intended demographic of middle income group to manage the cost of living in the context of urban areas. The residential houses are provided in the sustainable community and be priced within the range of RM 100,000 to RM 400,000. However, most of high rise residential development will be planned and further developed in the context of urban areas. Hence, this study will focus into the types of unit layouts of vertical living based on the following projects as the case studies.
Case Studies of HDB in Kuala Lumpur, Malaysia
1. PR1MA @ Jalan Jubilee, Kuala Lumpur
This development is one of the high rise affordable residential housing project located in the city centre and accessible through Jalan Loke Yew and Jalan Jubilee. This project offered three basic types of unit layout in the total of 543 units in 2.5 acres of land, which is shown in Figure 1 below. This development has included amenities for community, such as surau, community hall, kindergarten, shops, nursery and playground, to ease the community to walk within their compound for the basic facilities.
The provision of three basic types of units, which comprise 3 bedrooms with 2 bathrooms for unit type A and C as well as 2 bedrooms with 2 bathrooms for unit type B, has given the opportunities to the small family to set up their family in the urban context. However, the vibrancy of community hardly to be achieved due to the development focuses into standardise the unit layouts into three basic types.

Impact of social benefits forward to the society
A diversity of high-rise residential units helps respond to the housing needs of communities at different stage of life course, it helps to provides opportunities for communities where people can move home without leaving their neighborhood. People first preference is often to stay living in their existing neighborhood where friends and support network are already well established.
Secondly, greater housing diversity in high-rise residential units can help to fosters more opportunities for a wide range of income groups to choose their ideal housing types in well-serviced locations. Social interaction with neighbor from different background of race, ethnicity, culture and occupation helps in developing good-neighborly friendly relations, thus build up a caring homeland.
Besides that, diversifying residential units foster a healthier community through the development of ‘walkable’ communities. The most sought neighborhood characteristics of all buyers is walkability, living in a healthy community is everyone’s dream. More and more of us want to be live within a safe and comfortable walking distance of the destinations that meet our everyday needs, such as work, place to shop, eat, services, play and good transportation options that take us to downtown. A provision of walkable community would also contribute to ensure residents health by encouraging walking and cycling as major transportation method. By improve the walkability in the urban city, it helps to reduce the social disadvantage caused by rising fuel prices and transport costs. Residents’ burden on living expense get reduced, thus guaranteed their quality of life with less stress.
CONCLUSION
This paper has studied the impacts of social benefits forward to the society for having a diversity of residential units’ design in the development. Through the analysis of the multiple case studies, it has shown that authority of Singapore has enforced the urban affordable development to have a diversity of residential units’ design in order to capture the needs of the present and future. Along the process of life-changing cycle, the developments in Singapore manage to foster the opportunities for the community to choose the housing in all the life stages. However, in Malaysia, PR1MA is still struggling in the planning process to capture the vibrancy of communities in most of the projects due to the market demands. Hence, diversity of residential design units not fostered the vibrancy of communities but, it also creates a healthier neighborhood, enhances the economic growth and it reduces the social issues.
