2. As a town originated from tin-mining and rubber estates in the 1960s,
Puchong is one of the fastest developing township in Klang Valley, starting from its
bloom in the 1990s, being developed mainly by IOI Properties Berhad Group and SP
Setia Berhad Group. This town is linked to major areas such as Kuala Lumpur,
Subang Jaya, Shah Alam and Putrajaya by highways, especially Damansara-
Puchong Highway (LDP) that cuts through Puchong.

3. The book chosen is “The Death and Life of Great American Cities” by urban
writer and activist Jane Jacobs (Project for Public Spaces, n.d.). In the book, Jane
Jacobs stressed on the importance of diversity for a thriving city economically and
socially, although for many city planners diversity is taken as a problem. The idea
focused in this analysis is the conditions for city diversity, where she proposed four
main conditions:
1. The need for mixed primary uses
2. The need for small blocks
3. The need for aged buildings
4. The need for concentration
These ideas of Jane Jacobs are chosen to study Puchong as a growing township
consisting of suburban residential, industrial, services and commercial, highly
populated by different age and income groups. In addition, to understand the failure
of parts of Puchong where shop lots are constantly vacant or going through vicious
cycles of closing down and re-opening of businesses through Jacob’s perspective.
Mixed primary uses is needed to insure the presence of people outdoor for
different purposes at different timings while being at common places. This ensures
that places in that city do not encounter problems such as mob-like scenes during
peak hours, then back to long hour of dullness when the tides of people are gone
(Jacobs, 1961). Besides, the continuity of movement of people throughout the day at
an area makes the street safer and encourages people to walk. As seen in Puchong,
most commercial buildings are eateries, banking, fashion retails and entertainment-
orientated. Services and facilities such as laundry shops, sport complex, library and
galleries etc should be provided to diversify the purpose of people to the area.

The need for small blocks can be defined as building blocks being short in
order to allow more turning opportunities (Jacobs, 1961). Referring to Figure 3, when
there are more turning points, there are more alternatives to arrive the desired
destination instead of the people being forced to take the same long path every time.
This enables more commerce too as people will be taking different routes and
passing by retails from different streets. This keeps more streets active, instead of
isolating them away.

5. Figure 4: More vacancies and less circulated
Figure 5: Highly circulated and full with businesses
Even with approximately the same block lengths, difference in street activities
intensity can be seen. The turning points in Figure 4 are more like alleys without
proper pedestrian path, thus reducing the desire of people to walk past it to the other
side of the block. Shop lots in Figure 5 have wider turning branches with shaded
walkways, creating desirable turning points.

6. Buildings varying in age and conditions are crucial due to its economic
possibilities and creating a sense of place for the area. Usually, aged buildings are
more affordable and this encourages new businesses to emerge (Jacobs, 1961). In
Puchong, a mixture of old and new spaces is present, allowing small and large
businesses to coexist, creating neighborhood of different incomes and uses (Allen,
2011).

7. Lastly, high density of people is required in the city for a vibrant community to
exist, as people are the source of the vitality of place. Yet, high concentration of
people in a place should not be confused to overcrowding which means too many
people living within each dwellings (Jacobs, 1961). As seen in the zoning diagram,
the commercial area in Bandar Puteri is larger than the residential area. There more
residential housings vary in types and prices, should be available to increase the
human density in that area, enabling businesses to sustain themselves with more
people to be served.
Jacobs’s conditions for diversity cannot be considered as the sole factors for
the success and failure of Puchong, yet it can be a reference to improve the quality
of the area.
