8 .1 .1 LANDSCAPE PLANNING CONCEPTS
The following diagram shows an overview of
the four landscape types proposed for Zones
B and C. These include:
Type A: Regimented Rainforest, a multi-
tiered and biodiverse planting of native spe-
cies, connecting the Academic Green to the
landscape of Kent Ridge.
Type B: Arcades, providing covered link-
age between the various buildings, Activity
Nodes and landscape spaces.
Type C: Themed Gardens, providing a vari-
ety of open spaces in the Academic Green for
passive recreation and study. These employ
a variety of planting, hard-scape, seating and
lighting to create unique identities.
Type D: Activity Nodes, offering spaces for
recreation and gathering, as well as a range
of uses to the academic community. Activ-
ity Nodes may be open or enclosed (with air
conditioning), partially or fully covered.
More information regarding Types A
through D is given in the subsequent pages.

8 .1 .1 LANDSCAPE PLANNING CONCEPTS
Landscape plays a vital role in any large campus. In an aca-
demic setting, where visitors are constantly passing from one
building to the next, it is critical that the landscape assume
more responsibility than simply being that green stuff or
leftover space between buildings. It is a means by which
students reach their destinations, as well as a destination in
itself.
At present, the NUS landscape is maintenance-intensive and
yet remains little-used, either for pedestrian passage or recre-
ation. Nonetheless, the current campus presents an existing
network of green spaces that is complex and rich, in spite
of a lack of landscape planning at the campus level. It is the
goal of the current exercise to create an over-arching series of
landscape guidelines to bring the courtyards, hillsides, road
verges and green buffers of NUS into a coherent system that
is simple to implement, sustainable, stimulating, and adap-
tive to future needs.
This plan does not propose major disruptions to the existing
distribution of landscape spaces, nor to the plants that are
currently established. However, there exists a need to am-
plify existing resources, as well as to supplement a landscape
that is principally composed of lawn and feature plantings
(such as would be found in Botanical gardens). These are nec-
essarily maintenance-intensive, as well as low in the repre-
sentation of native species that will contribute to the health of
the campus landscape.
The NUS landscape, as in the case of Singapore more gener-
ally, is one that has resulted from large-scale disruption; little
of the former equatorial dipterocarpforest exists, and much of
the current stock was imported, prior to independence, from
other British colonial holdings.

8 .1 .1 LANDSCAPE PLANNING CONCEPTS
Landscapes of surprise
An important principle of the landscape mas-
ter plan is to incorporate a broad-spectrum
approach to design. This proposal aims to
maintain and augment the different types of
landscape spaces, creating a rich sequence of
landscape spaces that strive to be distinctive in
character and qualitatively different from their
surroundings.
Open spaces should generate surprise and plea-
sure, inviting the user to linger. From an aes-
thetic viewpoint, the current landscape suffers
from a dual problem:
1. A monotony of the general landscape that
contributes to a system of open spaces that tend
toward similarity of experience, and do not
encourage the user to take full advantage of the
broader facilities.
2. A selection of disparate smaller landscapes
that are themed, locally-developed in an ad-
hoc manner.
This proposal aims to improve the quality of
the general landscape through the clarication
of landscape elements, using an inll land -
scape technique. It also proposes to make sense
of the existing themed gardens by introducing a
system of such gardens throughout the campus
proper.
While achieving these goals, this proposal
simultaneously addresses the aesthetic goals
as well as the pragmatic challenges of mainte-
nance and sustainability.
A number of the existing NUS landscapes have great potential to contribute a special quality tothe campus; however, many of these currently show a history of ad-hoc management.
Inll landscaping
It is notthe recommendation of this master plan
that new landscapes at NUS should be con-
structed as if on a greeneld site. While some
spaces will involve completely ground-up
implementation - such as the new Academic
Green - it is intended that existing natural re-
sources, trees and shrubs, should be maintained
and incorporated into design improvements
wherever possible.
As such, the existing landscape provides a
frame-work for future works, where inlling
of additional specimens (as well as new hard-
scape and program areas) can take place.
Currently, the biodiversity of the NUS campus
is notably low; landscapes tend to consist of
a background of lawn and canopy trees, with
periodic planting of shrubs and ground-covers.
In some cases (see image at right), this has re-
sulted in a feeling of desolate or under-tended
environments - what one observer called green
deserts. These should be taken as opportuni-
ties to ll in the landscape, increasing Green
Plot Ratio by reintroducing hardy native species
where possible.
Other sustainability issues will also be ad-
dressed; the planting schemes propose to in-
crease leaf area indices so as to increase shady
areas that might encourage outdoor walking.
The amplication of existing spaces through the
admixture of programs, lighting, furniture and
features is also recommended.

Space for improvement
The existing landscape at NUS, as noted above, depends heavily upon lawn, tree, and very occasional shrubplanting. This establishes an effective framework for the future landscape of the campus. However, by itself this
planting scheme creates a number of sub-optimal conditions for the user.
1. Extensive lawn cover doesnot help to mitigate storm-water run-off, creating aburden on drainage systems.
2. Lawn is water and fuelintensive to maintain.
3. On topography too steepfor human habitation, thereis no necessity to use turf-ing as opposed to shrubs or
groundcover.
4. Planting of shrubs in adispersed fashion discour-ages use by birds and micro-fauna, which prefer swaths
of contiguous planting cover.

8 .1 .2 LANDSCAPE TYPES
Type A: Regimented Rainforest
These extend as green ngers from Kent Ridge to
create a landscape of native species in multiple tiers
at certain areas of the campus. As in Zone A, these
are understood as extensions of the secondary forest
landscape at Kent Ridge. The planting of Regimented
Rainforests is simplied and structured to avoid the
messy appearance of secondary forest, which may
strike the user as unkempt, and thus be considered
inappropriate for campus landscaping.
Regimented Rainforest is developed in conjunction
with Associate Professor Hugh Tan of Department of
Biological Sciences/ RMBR.
Type B: Arcades
Any system of paths proposed for the NUH and NUS
campuses will be required to work within the Singa-
pore climate. Intense heat and occasional storms are a
reality of this environment. As such, the current plan
proposes a network of Arcades - covered walkways or
colonnades - that link all buildings and provide shade
and cover for staff & students. These are used to link
Activity Nodes as well as buildings, and are hoped to
encourage student use of exterior spaces.
Type C: Themed Gardens
The notion of a campus in a rainforest will be bal-
anced with Themed Gardens. In the options presented
here, Themed Gardens are used to dene common areas
between new and existing buildings in Zones B and C.
Themed Gardens, placed alongside Regimented Rainfor-
ests and Arcades are understood to provide these Zones
with a clear and unique identity.
Type D: Activity Nodes
Activity Nodes comprise covered activity areas for groupevents, student amenities, learning spaces, as well as
passive recreation. These are understood largely as archi-
tectural elements such as green-roofed pavilions or other
enclosed spaces.
Nonetheless, it is expected that some Activity Nodes can
be designed as sheltered landscape areas. Primarily hard-
scape, these would have feature canopies and other ele-
ments of interest. The latter may also include feature seat-
ing and lighting, as well as artwork and paving systems. It
is encouraged that attractive and innovative shading and
roong systems are explored for these areas, to encour-
age more student use of semi-external spaces despite thegenerally hot & humid Singapore environment.
Landscape elements with distinct charac-
teristics
To achieve the Landscape Planning Con-
cepts, the landscape is devised as a system of
parts that can be implemented by phasing in
parts or as a whole. These parts correspond
to different Landscape Types with distinct
characteristics.
Regardless of the nal Master Plan Option
chosen, the landscape plan will consist of
these four elements, which can be re-orga-
nized in a modular manner to best suit the
architectural elements of the plan. Below, we
show how these Types would be arranged to
suit the Master Plan.

8 .1 .3 MASTERPLAN NESTED CAMPUS OPTION
The preferred Nested Campus master plan
features a double-row of buildings for FoS
and SoM that maintain a clear central green
space. The Formal Boulevard of NUH area
extends into NUS and becomes the central
axis in a network of Arcades, and leads di-
rectly to University Hall. Arcades crisscross
the expanse of landscape dened by the
building edges, creating Themed Gardens
between them.

8 . 2 T Y P E A : R E G I M E N T E D R AI N F O R E S T
A secondary forest landscape
The Kent Ridge landscape is a major landscape
amenity for the NUS and NUH campuses. As a
lush stand of secondary forest, this is one of few
remaining landscapes of its type in Singapore.
There are intact regions of native secondary forest
in the interior of the hillside (set back from Kent
Ridge Road) and areas of the slope are protected
natural reserves.
The role of Kent Ridge is not as an inhabited
landscape, but rather as a green reservoir that
assists in maintaining the ecological health of the
campus. It is recommended that these areas be
conserved and protected, and their perimetersreinforced with additional planting of native spe-
cies, such that invasive species do not inltrate.
Small viewing decks may be placed at the perim-
eter, such that users of the NUS campus can ex-
perience the Kent Ridge landscape more closely.
However, incursion of pathways or boardwalks
into the perimeter is not recommended as these
might prove disruptive to the forest ecosystem.
Within-forest bat roosts should be introduced
where possible, to reduce the current problem of
bat roosting/ guano on buildings at NUS.
Regimented Rainforests are extensions of this
Kent Ridge landscape into the NUS/NUH cam-
pus. The planting scheme which will characterize
this landscape is described in detail in Chap 8.2.2.
Regimented Rainforests brings the unique character of the Kent Ridge landscape into the campus.

8 .2 .2 LOWER KENT RIDGE ROAD - A ROAD IN A RAINFOREST
Landscape at Lower Kent Ridge Road
Lower Kent Ridge Road (LKRR) remains the central ve-
hicular accessway for the NUH and NUS campuses, and
provides a point of entry from South Buona Vista Road. As
such, LKRR forms a major ceremonial axis - it is the central
processional space and has a strong inuence on the visi -
tors impression of character and quality of the campus
landscapes.
LKRR benets from a collection of mature canopy trees that
assist in providing shade, as well as forming an attractive
green envelope around the roadway. Small shrub plantings
are to be found on either side of LKRR, as well as at spo-
radic points along the median.
The master plan proposes to strengthen the existing char-
acter of LKRR through additional planting. While canopy
tree plantings have historically tended to be monospecial,
it is recommended that additional native canopy species be
added to wayside rows. This adds to biodiversity, and also
makes LKRR less vulnerable to the threat of canopy extinc-
tion by pest or disease.
Likewise, the addition of native shrubs and understory
planting is highly recommended, in particular on the east
side of LKRR. Here, the road closely abuts the AYE, and
at present inadequate visual screening exists between the
campus and the highway.
Understory planting should be executed in the manner of a
Regimented Rainforest, using a selection of native species
in a multi-tiered distribution to be a lush, attractive cor-
ridor. The route should likewise incorporate elements for
shading, seating, and safe passage across vehicular roads.

8 .2 .3 SPECIAL CONDIT IONS - MAINTAINING V ISUAL CONNECTIV ITY
Across large vertical drops
At Block S5, between Kent Ridge Road and
the Academic Core at the +122 level, there
is a vertical drop of approximately 40 metres.
At this location, most of the drop occurs over
an existing slope. At the base, however, is
a retaining wall condition that produces a
sharp discontinuity between the landscape
of the Ridge, and that of the NUS campus.
It is suggested - at this particular central
green nger - that the vertical drop be medi-
ated via the localized addition of landscape
ll, creating an achievable, gentle slope of
15 degrees. With Regimented Rainforest
planting, a continuous green nger can be
achieved.
At interface between buildings and landscape
The green ngers of Regimented Rainforest extend-
ing from Kent Ridge may occasionally be interrupted
by a building. Yet it is important that these ngers
continue as if through these buildings to the other
side such that they form visible and robust elements
of the campus landscape.
To maintain a visual connectivity, the Regimented
Rainforest planting scheme can extend to the plant-
ing on the grounds directly surrounding these build-
ings.
Along the axis of these green ngers, a green-roofed
canopy or walkway can extend from the building
face to act as a transitional element between the for-
est exterior and the building interior.

It is an assumption of this master plan that destroying existing landscapes
to build new ones is counter-productive. A benet of regimented rainfor -
ests is the ability to maintain existing mature specimens and incorporate
these within an expanded planting palette.
In the common instance of canopy trees distributed in a row, or grid, regi-
mented rainforests may be added within a similarly narrow or linear zone,
surrounding the existing.
At left are diagrams showing one preferred method of inlling/nativizing
in which inll species of different types are layered beneath and between
existing canopy trees.
Additional planting should be introduced with a visible order to prevent
the new landscape from appearing messy. To this end, it is encouraged
that inll understorey trees be monospecially clustered in the interval
between each pair of existing canopy trees. Species may vary from interval
to interval, similarly for shrubs, small trees, and epiphytes. It is preferred
that shrubs and groundcovers form a gradient of height, becoming shorter
towards the perimeter.

density.
As shown, understorey shrubs and trees can
be easily added around and below existing
canopy trees to achieve the desired outcome.

An extensive and pleasant pedestrian route
An academic campus requires an extensivepedestrian network that offers a comfortable,
sheltered pedestrian experience and ex-
ibility of routes. To this end, the Arcades are
designed to crisscross the open space be-
tween the buildings of FoS and SoM, linking
academic buildings, Themed Gardens and
Activity Nodes.
In contrast to the singular and expedient
Formal Boulevard of NUH area, the Arcades
of NUS (FoS, SoM & FoD) range across the
campus to link its various components.
It is desired that the network comprises a
variety of Arcade types, each designed in
accordance with the following guidelines.
These Arcades will remain unied by the
strong geometry of the network in the Plan,
and by other unifying elements described in
the following pages.

8 .3 .2 TYPE B : ARCADES - DAY ONE SCENARIO
Starting with a clear gesture
The goals of a Campus Master Plan are nec-
essarily sweeping, and will take decades toimplement. During this time, it is reasonable
to expect that other planning priorities and
concepts will be introduced. It is unlikely
that the present Master Plan will be exactly
implemented as envisaged in 2009, without
modication.
However, it is important to establish certain
elements, anchors or touch-stones that
provide a clear and appealing structure that
will maintain in spite of changes to the evo-
lution of NUS campus.
To this end, it is proposed that a central
pedestrian axis linking the NUH, MRT, and
the broader NUS campus be considered as
such an element. As a relatively light (in-
expensive, quick and minimally destructive)
element, a pedestrian route seems to offer an
effective place to start.
The exact course of this route may, in future,
shift to take advantage of new openings pro-
vided by the subsequent removal of existing
buildings. However, a clearly appreciable
gesture on Day One will help to place this
element within the campus landscape.
An additional benet to this strategy is the
impression that major changes are afoot
from the very inception of this scheme - an
impression that can be produced without
major capital expenditure.

8 .3 .3 VARIETY OF SPATIAL ENVELOPES
Those familiar with the NUH and NUS
campuses will be well aware that many
existing circulation paths are planned forgreat lengths, while maintaining a consistent
length and character. While efcient, this
can lead to a monotonous experience for the
user, and suggests that the campus is to be
bypassed rather than enjoyed.
In contrast to the standard pedestrian link-
way, in which the spatial envelope remains
constant, it is proposed that new pathways,
such as the central spine, make use of avail-
able peripheral spaces to expand at the side
where possible and where appropriate. Small
gardens are created at either side. This lendsan element of surprise and relief, and pres-
ents the pedestrian routes as linear parkways
rather than infrastructural corridors.
Paths may expand to accommodate adjacent Themed Gardens

8 .3 .4 C IRCULATION
One of the central roles of the landscape
master plan is to support the experience of
the user during the process of circulatingacross the many spaces of the campus. Care-
ful choices of hardscape and softscape - both
in type and in distribution - can assist in
making movement at NUS both clearer and
more pleasant.
The goal of the future master plan is to es-
tablish a circulatory system that, while main-
taining multiple routes across the campus, is
nonetheless clear and user-friendly.

In addition of high-quality execution at the detail level, Ar-

methods to provide comfort as well as visual interest and vari-
ety between areas in NUS campus.
Such variations may include: expressive geometries in the ceiling
plane, optical effects such as changes in color and porosity, form
and geometry of columns and structural elements; and incorpora-
tion of occasional lighting, seating, and art work.

Gardens as place-makers
It is imagined that each Themed Garden willpresent a fresh destination to visitors to the
NUS campus.
To achieve this, each Garden should employ
a characteristic set of landscape techniques to
create its own distinct identity. These can in-
clude the use of particular planting palettes,
material palettes, paving patterns, water
features, earth works, and lighting schemes,
amongst others.
Not only will there be an increase in points
of interest within the campus, there will alsobe a system of gardens that help to create
identities within the larger landscape. By in-
creasing imageability of various parts of the
campus, these gardens can help to orient the
user within NUS.
Existing Gardens
NUS already has a system of extant Themed
Gardens. However, these have heretofore re-
mained largely as localised phenomena and
have been developed on an ad-hoc basis.
By introducing an entire patchwork of
Themed Gardens, the existing and new land-
scape parcels become unied in an overarch-
ing landscape planning concept that ties the
disparate parts of the NUS campus together.

Special circumstances
While most Activity Nodes will be enclosedgreen-roof structures, there may be certain
circumstances where a landscape-based Ac-
tivity Node may be desired.
In these cases, it is proposed that these land-
scapes will be characterised by a predomi-
nance of hardscape, and/ or the presence of
a feature canopy.
These canopies will provide both a visual
signature to the Node, but also provide relief
from the heat and rain. It is intended that
these areas will be aesthetically and environ-mentally attractive to students such that they
will be encouraged to spend time outside of
the academic buildings themselves.
The surrounding landscape should be con-
sidered in the design of the ground plane of
these spaces. It is encouraged that no distinct
separation between the two should be made
as this might deter visitors from crossing into
the landscape.
It is intended to create favourable circum-
stances for increased outdoor use.

8 .7 TRE E CONS E RV ATION S TRATE GY
For Tree Conservation Strategy, please refer to Nparks guide-
lines for Development Control Submission for Private/Public
Building Developments.
Under the Parks & Trees Act S14, written approval must be
obtained from the Commissioner of Parks & Recreation to
remove or cut any tree with a girth exceeding 1m, unless it is:
i. for the prevention of imminent danger; or
ii in compliance with any obligation imposed by any
written law; or
iii an expendable species listed in Annex 5.
It is a general recommendation that all existing trees be re-
tained unless felling is deemed necessary for future construc-
tion, or as above.
Topographical surveys with detailed surveys shall be carried
out for specic areas as required. Surveys shall be conducted
during planning and design stages of new works, to ensure
that all trees and relative soil/ground levels are accurate at
the time of construction.
Existing trees are shown at right.

Suggested paving patterns Built examples of recommended paving material and patterns which are textured, durable andsustainable. and those which are not recommended.
Activity areas should create interest through a lively use of materials and patterns. These may take advantage of the growing market in recycled
paving products and reconstituted woods to create a ground surface that is textured, durable, and sustainabl e.

A variety of lighting options
Lighting can add invaluably to the experi-ence of a landscape. Landscape in turn offers
many different contexts in which lighting
effects can be produced. The NUS campus
would do better to avoid traditional institu-
tional lighting provisions, such as mast lights
at regular intervals.
While it is important that the campus is well-
lit for safety reasons, there are numerous
ways in which this goal can be achieved. It
is likewise important to acknowledge that a
well-lit public space will represent a range of
lighting atmospheres from bright to restful.

A variety of seating options
In the contemporary campus environment,it is acknowledged that seating of various
kinds can contribute a sense of fun and aes-
thetic interest. It is no longer expected that a
single bench type be employed throughout a
common campus. Rather, different areas can
benet from the unique identity conferred by
a combination of lighting, seating and other
landscape elements.
