    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.

    202 LANDSCAPE

    NOV 2009

    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.

    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.

    amount of lawn and related water consump-tion, and increase biodiversity and green

    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-

    cade structures should take advantage of a full range of design

    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.

    The Academic Green is essentially an extensive green roof. Efforts should as well be made to introduce green roofs to LTs and activity pavilions

    within the Academic Green. Some successful built examples of both extensive and intensive green roofs are shown here:

    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.

    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.

    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.
