Did you know an educational campus near the Singapore Botanic Gardens was designed to manage tropical heat before modern air-conditioning became an everyday expectation? The buildings of Former Raffles College demonstrate how architecture can use shade, ventilation and open space to make learning environments more comfortable.
At 469 Bukit Timah Road, rows of wide arches frame long covered passages, with buildings arranged around green quadrangles. Today the site is part of the NUS Bukit Timah Campus, but the underlying architectural ideas were developed for a college in the late 1920s.
The quick answer: Raffles College began classes in 1928 with 43 students. Its campus used broad verandahs as buffers against direct sun, numerous windows for ventilation and arcades facing shaded courtyard spaces. The buildings were preserved for their historical and architectural value; six were gazetted together as a National Monument in 2009. The design illustrates passive cooling principles, but it does not mean every room always remained comfortable without mechanical assistance.

1. Why was a college built on Bukit Timah Road?
The idea of establishing Raffles College developed from a proposal to mark the centenary of Stamford Raffles’ arrival in Singapore. Colonial authorities and donors considered an educational institution a meaningful memorial and a step toward higher learning within the region.
The college was eventually constructed in Bukit Timah, near a road connecting the city to the island’s interior and close to the Singapore Botanic Gardens. It was designed as an arts-and-sciences institution rather than a small group of detached classrooms.
Classes began in June 1928 with the first cohort of 43 students; formal opening ceremonies followed in 1929. Keeping those dates separate is useful: students were using the campus before its ceremonial opening.
The campus later became part of several stages of tertiary education in Singapore, including the University of Malaya, the University of Singapore and the NUS institutional lineage.
2. What is a quadrangle?
A quadrangle is an outdoor space enclosed or framed by buildings, often used in traditional university design. The old Raffles College plan included multiple blocks oriented around two courtyard-like quadrangles.
Instead of placing every building directly in one long line beside a road, the plan created green internal spaces that offered a recognisable centre to campus life.
A courtyard can influence daylight, views, breezes and social interaction, although its performance depends on the dimensions of surrounding buildings, planting, exposure to sun and direction of wind.
The National Heritage Board identifies the two quadrangles and the buildings arranged around them as a key part of the campus architecture.
3. How can an arcade protect students from the sun?
The ground-floor buildings have a sequence of wide arches that form covered arcades. These passages provide a sheltered transition between open courtyards and interior rooms.
An arcade lets a person move along a building with less direct exposure to sun and rain than a completely open path. The walls behind it also receive less direct solar radiation because the projecting veranda or passage provides a buffer.
That can lower heat gain in some situations, particularly when sunlight would otherwise strike the building’s outer wall or windows. But the size of the benefit depends on the orientation, season and exact form of each arch and passage.
The key idea is that shade is part of the architecture rather than something added by a movable umbrella.
4. Why did the architects include so many windows?
Before mechanical cooling was widely available, windows were essential to admitting daylight and allowing air movement through occupied rooms. The Former Raffles College buildings have many openings and generous verandahs.
When conditions permit, natural ventilation can carry heat and moisture away from indoor spaces. A breeze entering through one opening may flow toward another, producing a more comfortable environment than a completely sealed room.
However, windows alone do not guarantee good cross-ventilation. Their placement, opening area, surrounding obstacles and outdoor conditions all matter. Heavy rain and humid, still weather can limit the benefit.
NHB describes the original campus as designed to allow ventilation and shade, supporting the interpretation that these features were deliberate responses to tropical conditions.
5. Why use green spaces instead of paving every courtyard?
Landscaping changes how an outdoor area feels. Trees can shade paths and walls, while vegetation gives students places to sit, meet or move between lessons away from exposed roads.
A shaded green quadrangle may be more pleasant than an unshaded hard-surfaced courtyard, especially in the midday heat. The effect depends on tree canopy, soil moisture, surrounding airflow and maintenance.
Those spaces also shape social behaviour. Campuses are not only collections of teaching rooms; students need places to gather, reflect, read and encounter others.
Yet the idea that the quadrangle alone cooled all nearby classrooms would be an overstatement. It was one part of a wider architectural composition incorporating arches, verandahs, windows and building spacing.
6. Who designed the original college?
The architects were Cyril A. Farey and Graham R. Dawbarn, selected through a design competition. NHB describes the campus as reflecting a restrained institutional architecture with broad arches and open verandahs.
The campus buildings were named in part for major donors, reflecting how philanthropy and public financing contributed to the creation of higher education. Names associated with the site include Oei Tiong Ham, Manasseh Meyer and Eu Tong Sen.
Design and sponsorship were separate roles. A benefactor might fund or be commemorated in a building without having personally designed its ventilation system.
That distinction helps students understand how institutions are built: a campus depends on architects, engineers, funders, administrators, teachers and the people who maintain it afterward.
7. What changed after the first college years?
Raffles College and King Edward VII College of Medicine merged to form the University of Malaya in 1949. The Singapore campus later formed part of the University of Singapore from 1962.
The National University of Singapore subsequently developed its larger Kent Ridge campus, but the old Bukit Timah site continued to serve educational and public institutions in different periods.
Some buildings were added after the original 1928 campus. For example, the historic library and other later blocks belong to different construction phases. This matters when interpreting photographs: one image may show part of a historic campus without depicting its earliest structure.
The campus remains an instructive record of change rather than a perfectly frozen 1928 tableau.
8. Why were six buildings protected as a National Monument?
In 2009, six buildings on the Former Raffles College site were collectively gazetted as a National Monument, recognising their institutional and architectural significance.
NHB identifies the Oei Tiong Ham Building, Manasseh Meyer Building, Eu Tong Sen Building, Federal Building, C. J. Koh Law Library and Li Ka Shing Building in the protected group.
National Monument status is not a claim that every present use is identical to the original college. It means these buildings have recognised national significance and their conservation and alteration require careful treatment.
Preserving the campus provides a physical way to study Singapore’s higher-education history, donor networks and adaptation of institutional architecture to local conditions.
9. What can a modern student learn from this design?
Imagine you must design a school building in a hot, humid place. You want enough daylight for reading, airflow for comfort, protection from rain and pleasant outdoor spaces.
Sketch a simple rectangular building with rooms on one side and a shaded verandah on the other. Add windows, a planted courtyard and a route between blocks. Then ask what happens when the afternoon sun reaches a wall, when wind is still or when rain blows sideways.
The design exercise reveals that passive measures can improve comfort but also involve trade-offs: deep shade may reduce daylight, large openings may admit noise, and open corridors require careful drainage.
Modern mechanical systems may still be necessary, but good passive design can make their task easier. That is the enduring lesson behind the original campus.
10. Can the public walk freely around the campus?
The former Raffles College buildings are a working institutional campus, not an unrestricted public park. National Monument recognition does not grant automatic entry to classrooms, offices or internal courtyards.
Before a visit, check the responsible institution’s published access arrangements or authorised heritage programme. Do not enter through security gates or photograph people in educational settings without permission.
Visitors can study NHB’s descriptions and archival photographs even when specific areas are inaccessible. A legitimate heritage lesson does not require crossing a campus boundary.
For a publicly accessible comparison of historic architecture and gardens, Cluny Court and parts of Singapore Botanic Gardens offer separate, approved experiences nearby.
11. How does Raffles College relate to the rest of Bukit Timah?
Bukit Timah contains multiple generations of educational infrastructure. The old Raffles College represents tertiary education and institutional architecture; nearby schools have their own histories; the Botanic Gardens represents scientific research and public education.
Major transport improvements came in different decades. The college existed long before the Downtown Line reached the area, so one should not reverse the timeline and say the MRT created the academic landscape.
The architecture is also part of a wider approach to Singapore’s climate. Five-foot ways, shophouse arcades and large verandahs use related ideas of shelter, although their buildings and purposes differ.
Did you know an arch and a courtyard could be part of a serious educational design decision? Raffles College shows how the form of a campus can affect how people learn, move and feel.
