Instruction
Answer following Question:
Based on Lecture 19 - 24 in https://www.udemy.com/sustainable-urban-development#/ and urban
renewal slides in Course Material Folder, give solution to the following problem
Kajang has transformed itself from a small old town to a big modern town by designing and
developing new township such as Bandar Baru Bangi and Bandar Seri Putra as well as extending its
CBD (central business district) such as extension to Sungai Chua. However, its centre is
inadequately transformed and most of its residences are working inKuala Lumpur and other external
areas. Write your vision and plan for Kajang to transform its town centre and to be a self reliance
town. You may use sketches to enhance your vision and plan.

3. Kajang is a town in the eastern part of Selangor, Malaysia. Kajang is the district capital of Hulu
Langat. It is located 21 kilometers (13 mi) from Malaysia's capital, Kuala Lumpur.The current
locational gravity of growth in Kajang would be Sungai Chua. The total population of Kajang
has grown rapidly in the past few years, with estimated population growth of 9% per annum. The
soon-to-be-realised Klang Valley MRT station in Bandar Kajang will boost the property value in
Sungai Chua.
Basically Kajang consists of a number of Malay, Chinese and Indian settlements. The
village areas largely are populated by Malays. The Chinese settlement pattern is scattered around
Kajang town. While rubber plantation areas are inhabited by settlers of Indian descents. If
viewed from its topographical perspective, Kajang sub-District is located on a highland area
which is approximately 76,250 cm from the sea level. Most of its landscape is hilly filled with
mountains. Its flatlands can be found at river-basins such as Sungai Langat, Sungai Bangi,
Sungai Semenyih and Sungai Chua. These areas are the early settlements explored in the Sub-
district of Kajang.
Figure 1 shows the map of MPKJ land use in Kajang. While the table 1 shows the total of
the MPKJ land use.
VISSION AND MISSION
The main vision for this plan is to make Kajang as a town where the residencesenjoying the
benefits of a sustainable economic growth and dwells in a friendly livable environment. The
mission is transforming Kajang town center to become a self-reliance town. The principle
objectives of the plan are:
i. All the new development not only adds to the range of facilities in the town centre, but
also improves the quality of the environment
ii. To ensure that new development is well related to existing areas and does not give rise or
lead to the potential for urban sprawl.
iii. To ensure that the alterations and extensions to existing buildings generally will improve
the environment and reinforce the sense of place.

4. iv. To create new buildings and houses this can enhance the special character of Kajang and
meet the needs of residents and other users.
URBAN RENEWAL
Urban renewal is a program of land redevelopment in areas of moderate to high density urban
land use. Renewal has had both successes and failures. Its modern incarnation began in the late
19th century in developed nations and experienced an intense phase in the late 1940s – under the
rubric of reconstruction. The process has had a major impact on many urban landscapes, and has
played an important role in the history and demographics of cities around the world.
Urban renewal involves the relocation of businesses, the demolition of structures, the
relocation of people, and the use of eminent domain (government purchase of property for public
purpose) as a legal instrument to take private property for city-initiated development projects.
This process is also carried out in rural areas, referred to as village renewal, though may not be
exactly the same in practice. In some cases, renewal may result in urban sprawl and less
congestion when areas of cities receive freeways and expressways.
Urban renewal has been seen by proponents as an economic engine and a reform
mechanism, and by critics as a mechanism for control. It may enhance existing communities, and
in some cases result in the demolition of neighborhoods.
Many cities link the revitalization of the central business district and gentrification of
residential neighborhoods to earlier urban renewal programs. Over time, urban renewal evolved
into a policy based less on destruction and more on renovation and investment, and today is an
integral part of many local governments, often combined with small and big business incentives.
Kajang can take urban renewal approach to redesign their city. But Kajang is an old town
and its involve so many aspects to be considered for example rehabilitation of old homes is
veryhard to be done. So by considering the existing Kajang, the main steps can be taken are
alterations and extension to existing buildings and construction of sustainable building.

5. 1. Alterations and Extension to Existing Buildings
Planning permission will be granted for alterations and extension to existing buildings which:
i. Choice of materials and positioning are compatible with the character of the existing
building.
ii. Will not result in an unreasonable loss of privacy or natural light to neighboring
properties.
iii. Will not be detrimental to the neighborhood amenities and the characters.
iv. Will result in more conformability and convenience.
v. Alterations and extensions to existing buildings generally raise similar design issues to
those of new development. Every change to a building, a street or a space has the
potential to enrich or, if poorly designed, impoverish a part of the public realm.
vi. The impact of a proposal on the appearance and character of the existing building and
street scene generally must be satisfactory and there should be no unreasonable loss of
amenity and privacy for immediate neighbors.
2. Construction of Sustainable Building
Planning permission will only be granted for development where its demonstrated that :
i. Energy needs have been minimized.
ii. Through a combination of design for energy efficiency and the incorporation of a
sustainable energy supply such as green energy generation or combined heat and power.
iii. New buildings should be designed and constructed to reduce their energy demands and
minimize their adverse effects.
iv. Other features will be incorporated to reduce or minimize environmental resource use and
impact.
v. Ensure that the rate of surface water run-off from a site is not increased by the
development proposed.

6. vi. In new housing developments, facilities are provided, and an environment created, that
encourages more sustainable lifestyles, for example, waste disposal facilities that support
recycling initiatives.
vii. The quality of Kajang’s built and natural environment should be respected and
improved to a complementary mix of uses.
viii. Mixed use development such as integrating housing with shops and employment
opportunities, can make the most of the potential for higher densities and intensive
activity at locations with good access to public transport.
3. Downtown Development and privatization of public spaces
Development will be permitted where all external spaces, including streets, footpaths, civic
spaces, other open spaces have been designed as an integral part of the scheme as a whole,
and it has been demonstrated that:
i. The design and the materials to be used are appropriate for their intended purpose, to the
use and character of the surrounding buildings and the area generally.
ii. Different elements of paving, landscape and street furniture are coordinated to avoid a
sense of clutter.
iii. Particular consideration can be given to the planting of trees to provide a setting for
buildings, boundaries and road sides.
iv. Public open spaces and pedestrian routes are connected with the pedestrian network
where the opportunity exists.
Proposals involving the loss of open space will not be permitted unless it is demonstrated that:
i. There will be no significant impact on the quality or character of the local environment.
ii. The open space is a small part of a larger area or of limited amenity or leisure value and
there is a significant overprovision of open space serving the immediate area.
iii. There will be a local benefit in allowing the development in terms of either alternative
equivalent provision being made in the area or improvement to an existing public park or
other open space or

7. iv. the development is for a community purpose and the benefits to the local community
outweigh the loss.
4. Naked Street and Masjid Centre
The naked streets approach is not a specific set of designs, but an underlying set of
principles. Depending on the context, different responses will be appropriate. However it is
essential that urban planners and transport engineers work together closely, to ensure that
traffic management concerns never overwhelm the need for our streets and public spaces to
be primarily places for people. A useful starting point is to establish where the location lies
on a movement/placematrix.
Figure 7.1 Naked Street in Kajang
Concept of naked street is remove all the things that were supposed to make it
safe for the pedestrian for example traffic lights, railing, curbs and road marking. Its
sound impossible to be done in Malaysia. But, this can be taken as first step to change our
mentality become a world class. What we can do to is giving drivers and pedestrians
equal status. Road humps, chicanes and other physical measures designed to reduce the
speed of vehicles would be removed and the question of who had priority would be left
open deliberately, making drivers more cautious. Traffic lights have been uprooted and

8. drivers must negotiate their way across junctions, forcing them to slow down and
establish eye contact with pedestrians.
One of Kajang landmark is Kajang mosque. So, masjid centered can be used to
transform Kajang become a friendly livable environment. Kajang mosque already located
at the town centre. What we need to do only emphasize the function and need of Kajang
mosque so that it will become livelier with Islamic activities. Then, we can redesign the
location or position of building for example shop houses and offices around the Kajang
mosque. We need to give an adequate facilities and amenities to generate the
development and sustainable economic growth around the mosque.

5. Modern Public Transport Facilities
Planning permission will only be granted where development provides for integration and
connection of development to enable access by all modes of transport. Development should
connect into existing transport networks to ensure it is convenient for travel to the site to be
achieved by all modes in order to provide genuine choice of travel.
Priority must be given to the main shopping streets center in developing pedestrian
priority measures, whether full pedestrian,footway widening or simply measures to enhance

9. the attractiveness and safety of the pedestrian environment. If necessary re-allocation of
space to pedestrians can be adopted, encouraging shoppers and visitors to enjoy the amenities
of the city center.
Building at Kajang city centre already centralized which located close to each
other. But, there is no pedestrian walkway. They needwalk along building perimeter which is
busy. So, good walking passages have to provide to ensure the safety and comfort for
pedestrians. This is to encourage them to walk to their desire place. Existing main road that
connecting from other places to Kajang are Kajang Dispersal Link Expressway, Cheras-
Kajang Expressway and Kajang-Seremban expressway.While the public transport that
connect the Kajang town and other city are commuter, bus rapidKL and taxi. The increasing
reliance on private transportation, in particular private cars, has created considerable pressure
on the roads network which caused the traffic congestion even not during peak hour.
Implementation of fully integrated transportation system to improve to the bus
networks are being facilitated by MPKj providing exclusive bus and taxi lanes in the City
centre and comfortable stop. Tram lined system which travel internally and around a Kajang
perimeter can be proposed to improve the public transportation facilities. In order to make it
greener, this tramline system is utilizing the electric energy as power of movement. This
electricity power produced by municipal waste. The interchange would be at existing KTM
kajang. People will take a tram to go into a city centre which has several station around city
centre (stadium, KPJ Kajang Specialist Hospital, Hospital Kajang, School, Metro Kajang).
Figure 7.3 The Usage of Tram

10. Other ways that can be taken into consideration is by providing a modern, fast
public transport such as subway or underground Metro systems Usage. It is because, we
can minimizing the usage of the land use. A part from that, by using subway we can
reduce the emission of carbon monoxide and also reducing the noise pollution in the city.
This metro system is an electric passanger transport system with high capacity and high
frequency of services that totally independent from other traffic, road or pedestrian. The
location of the subway connecting the residential area to the commercial area at the
centre of the city and also to the Sungai Langat region. This Subway also linkage to
Balakong which is industrial area. Currently under progress,is the Klang Valley MRT
from Sungai Buloh to Kajang.

6. Shopping / Economics Development
Planning permission for retail development in the city centre with the following
considerations:
i. Provide high quality, commercially attractive units to a high standard of design that will
strengthen the role of this area as a regional shopping centre, safeguard historic character
and improve the appearance of the city centre.
ii. Reinforce the vitality of the shopping streets in the central area.
iii. Paid special attention to upper floors which are not to be used for shopping purposes,and
how these may be put to, or brought into beneficial uses which will enhance citycentre
character.
iv. Help to create a safe and attractive pedestrian environment, safeguard historic character
and improve the appearance of the city centre including the public realm.
