Be Inspired by the Visions, Creativity and Stories Behind Singapore’s Architectural Legacies at the Singapore Architecture Collection’s Inaugural Showcase

- The “To Draw an Idea: Retracing the Designs of William Lim Associates – W Architects” and “Dare to Design: Singapore Architecture 1960s – 2000s” exhibitions present the most comprehensive collection of Singapore’s architectural materials to-date.
- Visitors to take away rich insights on the evolution of Singapore’s cityscape, society and identity through the lens of extensive architectural resources.
- Series of exciting programmes lined up for the young and old to discover how architectural efforts shape a liveable and endearing Singapore.

Explore and learn about how Singapore’s post-war architecture reflected the evolution of the nation’s built environment, society and identity in the inaugural showcase of the new Singapore Architecture Collection. Jointly organised by the National Library Board (NLB) and Urban Redevelopment Authority (URA) in partnership with local architecture firm W Architects, the exhibition “To Draw an Idea: Retracing the Designs of William Lim Associates – W Architects¹” features over 500 architectural archival materials and artefacts. It was launched today by Ms Indranee Rajah, Second Minister for National Development and Finance, and Minister in the Prime Minister’s Office. Also launched on the same day is NLB’s “Dare to Design: Singapore Architecture 1960s–2000s” satellite exhibition at the National Library Building, celebrating Singapore’s architectural legacy and allowing Singaporeans to check out architecture stories across multiple locations nationwide.

"To Draw an Idea” presents insights into how visionary and innovative designs were inspired by the times and in turn, shaped Singapore’s urban development, distinctive cityscape and unique identity. It features the first comprehensive contribution from an architecture firm to the Singapore Architecture Collection that was announced in August 2023, and showcases archival materials of William Lim Associates – W Architects’ 19 key projects from the 1980s to the 2010s. On display include architectural drawings and artefacts from the refurbishment of the National Museum of Singapore, to residential projects like Paterson Edge which introduced compact city living and early adaptive reuse proposals for heritage areas such as the Singapore River. They reflect the evolution of the firm’s work across four decades and demonstrate how global architectural influences, local developments, building regulations and changing aspirations amongst the population have influenced the firm’s design processes and creative visions over the years.

The collection seeks to document, preserve and make available a wider repository of significant archival materials on Singapore’s modern and contemporary architecture. Materials donated to the collection will be carefully preserved and protected against material deterioration. For more information about the collection, refer to Annex A.

NLB’s Chief Executive Officer, Mr Ng Cher Pong, said: “This inaugural showcase from the Singapore Architecture Collection tells our rich Singapore Stories through the materials generously contributed by our local architecture community. Everybody has their own memories of many of the landmarks featured, such as the Victoria Theatre and Concert Hall. We hope that through this exhibition and the setting up of the Singapore Architecture Collection, we will be able to inspire even more Singaporeans to share their stories and help build our shared heritage and identity.”

URA’s Chief Executive Officer, Mr Lim Eng Hwee, said: “We are encouraged by the strong support from the industry since embarking on the collection. By preserving valuable resources from Singapore’s architectural heritage, built environment industry professionals and the wider community can gain an appreciation of how our urban environment has evolved over the decades in response to our changing needs and aspirations. We will continue to partner industry and academia to grow the collection not only as a rich resource for research and education, but also to inspire the future as we work to continuously shape a liveable and endearing home for generations of Singaporeans to come.”

W Architects’ Managing Director, Mok Wei Wei, said: “Building and sustaining a rich archive serves as a valuable record of our cumulative knowledge. It encourages us to reflect on our own works and can be used for research on Singapore’s architecture. Such an archive is also important for Singapore as it contributes to our understanding of our built heritage. Of all the designs and drawings that we produce, not everything is realised, not everything will remain intact, not everything will stay. This means the architectural materials, together with published documents, become the only tangible things that survive to tell the story of the creative endeavour of architects, and the cultural legacy of the society they live in.”

“To Draw an Idea: Retracing the Designs of William Lim Associates – W Architects” exhibition will run for six months from 28 November 2023 to 8 June 2024 at The URA Centre ground floor atrium. Admission to the exhibition is free. Refer to Annex B for the exhibition highlights.

Visitors can participate in guided tours of the exhibition, talks by subject matter experts and children’s workshops at the URA Centre and National Library Building. They can sign up for these programmes via https://go.gov.sg/tdai-progrm-collection. Refer to Annex C for the exhibition programmes.

The “Dare to Design: Singapore Architecture 1960s–2000s” satellite exhibition shares design insights and stories behind some of Singapore’s unique and innovative landmarks and buildings built from the 1960s to 2000s, such as the Golden Mile Complex, Pearl Bank Apartments and the National Theatre. Through books, building plans, photographs, videos and other materials on display, the public can learn more about the Singapore’s architecture story and journey, and the many bold ideas and visions in building design that have captured hearts and minds across time.

“Dare to Design: Singapore Architecture 1960s–2000s” will also run for six months from 28 November 2023 to 9 June 2024 at the National Library Building’s lobby. Admission to the exhibition is free. A roving display of the “Dare to Design” exhibition will also tour at the following locations:

About William Lim Associates and W Architects

Founded in 1982, William Lim Associates (WLA) was the third firm (the two other firms are the Malayan Architects Co-Partnership and Design Partnership) affiliated to architect William S. W. Lim (1932-2023), who had contributed to Singapore’s post-independent architectural landscape. Together with his contemporaries, he had designed significant buildings such as People’s Park Complex and Golden Mile Complex. A prolific writer and thinker, Lim significantly shaped Singapore’s architectural discourse.

Architect Mok Wei Wei joined WLA in 1982, eventually becoming the lead architect for many of the firm’s groundbreaking projects. The firm was renamed W Architects (WA) after Lim retired from practice in 2003. Currently the Managing Director of W Architects, Mok’s numerous architectural projects have received critical acclaim both locally and internationally. His works have been featured in numerous regional and international publications. He was conferred the President*s Design Award in 2007. Mok is currently a Professor (Practice) of the National University of Singapore and Chairperson of the Department of Architecture’s Industry Advisory Board.

Annex A - About the Singapore Architecture Collection

Building upon the rich architectural materials in the National Library and National Archives of Singapore, the Singapore Architecture Collection seeks to document, preserve and make available a wider repository of significant archival materials on Singapore’s modern and contemporary architecture that symbolise our growth as a city as well as strengthen our national heritage and identity

The collection comprises architectural models, photographs, drawings, artefacts, oral history recordings and more, contributed by architects, planners, urban designers and other professionals from the built environment industry. These materials not only capture Singapore’s architectural and urban design journey through the innovative works of pioneer and current practitioners, but also provide a rich resource for research, education and design inspiration in shaping Singapore’s built environment for present and future generations.

The collection is managed by the Urban Redevelopment Authority, the National Library Board and the National Heritage Board, in close partnership with the Singapore Institute of Architects, the National University of Singapore and the Singapore University of Technology and Design. It forms part of a larger collaborative effort to build up a design collection for the nation, which covers a range of disciplines, from fashion to graphic design and architecture.

Contributions to the collection to date

In addition to William Lim Associates – W Architects, other architects and firms have also contributed to the collection. They include architects Chan Sau Yan Sonny, Tay Kheng Soon and Dr Goh Chong Chia, and architectural firm, RSP Architects Planners & Engineers.

The collection is still growing and welcomes contributions from others.

Architects, planners, urban designers and others in the built environment industry interested in contributing to the collection can write to enquiry@nlb.gov.sg.

Public programmes and access

The public and industry can learn and discover more about the Singapore Architecture Collection by participating in a series of initiatives, starting from the “To Draw an Idea” exhibition and public programmes. The full collection can be accessed on the National Library Board’s OneSearch, at search.nlb.gov.sg/onesearch, while writeups on key materials can be found in the Singapore Architecture Collection booklet at www.go.gov.sg/sgarchitecturecollection.

Highlights from the collection

Below are notable materials currently in the Singapore Architecture Collection.

Items	Details
Architectural drawings and plans
	National Theatre drawing, 1960 Ground floor plan of the National Theatre, 1960. Donated by Alfred Wong Partnership, courtesy of National Archives of Singapore. Designed by architect Alfred Wong and opened in 1963, it was Singapore’s first National Theatre. Some of its key features include its five-point façade that represented the five stars of the Singapore flag and its large, cantilevered steel roof over the open-air auditorium. It had a stage with a revolving platform and ample spaces for dressing rooms and storage space. While it was demolished in 1986, the building’s history and stories can still be told through drawings, photographs, oral history recordings and other materials.
	Jurong Town Hall drawing, 1970 South-west elevation of Jurong Town Hall, circa 1970. Designed and donated by Datuk Seri Lim Chong Keat, courtesy of National Library, Singapore. Completed in 1974, Jurong Town Hall served as the headquarters of the Jurong Town Corporation (currently known as JTC Corporation) formed in 1968 to spearhead industrial growth. Over the years, it has become a symbol reflecting the bold imagination, inventiveness and the resilient spirit of our early nation building efforts. The cantilevered upper storeys give the building the appearance of a ship’s hull with its tall clock tower serving as the ‘mast’. It was designated as a national monument in 2015 as a significant symbol of Singapore’s national identity and heritage.
	Kampong Bugis Guide Plan, 1989 Section of the proposal for Kampong Bugis, developed by architect Tay Kheng Soon and the Singapore Institute of Architects team, 1989. Donated by Tay Kheng Soon, courtesy of National Library, Singapore. Tay Kheng Soon’s 1989 Kampong Bugis Guide Plan was ground-breaking for many due to its environmentally conscious tropical architecture features that were novel then but have been well-adopted today. For example, extensive vegetation was proposed on the vertical surfaces of buildings, with vertical shading and naturally ventilated breezeways to reduce the use of air-conditioning. Vertical green buildings became more prevalent from the 1990s. The guide plan was developed as part of URA’s Master Plan Review in 1990. The Singapore Institute of Architects (SIA) was commissioned to develop master plans for selected areas around Singapore. Led by Tay, the SIA team included Lai Chee Kien, Rob Hearne, Chua Beng Huat, Bob Powell, Patrick Chia, Winston Yeh and Chung Meng Ker.
Physical model
	Model of of Assyafaah Mosque, 2004 Designed and donated by architect Tan Kok Hiang, courtesy of Urban Redevelopment Authority. The design of the mosque adapted traditional elements to create a contemporary version of the arch, minaret and the arabesque.
Photograph
	Beverly Mai photograph, 1974 Photograph of Beverly Mai. Donated by architect Dr Goh Chong Chia, courtesy of National Library, Singapore. Singapore’s first condominium built in 1974 was designed by architect Timothy Seow (1938-2019), who designed some of the earliest high-rise condominiums in the 1970s.
	Annual renewal certificate, Ho Kwong Yew, 1938 Board of Architects annual renewal certificate of the first local-born registered architect in Singapore, Ho Kwong Yew, 1938. Donated by Kelvin Ang Kah Eng, courtesy of National Library, Singapore. Ho Kwong Yew (1903-1942) was one of the leading Asian architects in 1930s who designed numerous modernist buildings. One of his more well-known works was a luxury mansion that used to be located where the current Haw Par Villa is today. It was built in 1937 for a Chinese businessman, Aw Boon Haw (founder of the Tiger Balm brand), but was demolished after the Japanese Occupation. Some of the buildings Ho designed have been conserved, such as the main house of the modern bungalow at 25 Grange Road, known as the ‘Wellington House’, and an iconic corner shophouse at 79 Circular Road.

Annex B - Highlights from the Exhibition “To Draw an Idea”

The exhibition is presented in three segments:

Items	Details
a) Refract – In search of fundamentals This segment features six projects in the 1980s and 1990s, exploring how the emergence of global post-modernist architecture and rapid urban renewal and modernisation efforts influenced architects William Lim and Mok Wei Wei in creating more responsive and sensitive designs to reflect local heritage, culture and contexts. An example is the Tampines North Community Centre. Other projects featured include two homes, a church and two conservation and adaptive reuse proposals for Kreta Ayer in Chinatown (1982) and Boat Quay of the Singapore River (entitled Bu Ye Tian, 1982), where both contributed to raising awareness and interest in early conservation efforts in Singapore.
	Tampines North Community Centre, 1989 East elevation colour study, 1986–1989, ink and pencil on butter paper. Courtesy of National Library, Singapore. Influenced by the experimental and exuberant Post-Modern architecture movement from the 1970s to 1990s, the design of this community centre is colourful, with a playful contrast of a perimeter colonnade and a collage of smaller blocks in various shapes, sizes, and colours, complementing and reinforcing each other.
	Bu Ye Tian (不夜天), 1982 Bu Ye Tian by artist Ong Kim Seng, based on architectural drawing by Mok Wei Wei. Courtesy of National Library, Singapore. Bu Ye Tian is an adaptive reuse proposal which imagined the Singapore River as a cultural destination. The proposal was commissioned by playwright and poet, Dr Goh Poh Seng (1936-2010), contributing to greater awareness and interest in early conservation efforts in the 1980s. The proposal recommended to retain 110 shophouses along two rows, which would become a thoroughfare for restaurants, food stalls, traditional craft trades and clan associations. Local artist, Ong Kim Seng, was engaged to depict the rich and vivid scenes of Bu Ye Tian for the proposal’s presentation, based on architectural drawings by architect Mok Wei Wei, when working at William Lim Associates.
b) Respond – Contextualism in a constricting environment This segment features six residential projects from the 1990s to the 2010s, revealing more detailed insights on the considerations behind building designs and how they responded creatively to planning requirements and regulations. The projects contributed towards introducing a wider range of housing designs and options in response to rising aspirations for new housing forms. Key examples include The Paterson Edge (1999), one of the first condominiums to offer compact living in the city as well as 11 Kim Tian Road (2018), which introduced a communal landscape deck with more amenities for residents, in response to guidelines to encourage more communal spaces and facilities.
	The Paterson Edge, 1999 Elevation, digital print on paper, 1996. Courtesy of National Library, Singapore. The Paterson Edge was one of the first condominiums that offered compact apartments for city living next to Orchard Road. Working within the site’s narrow configuration, its street-facing facade was expressed in the form of a glass curtain wall that gave residents an expansive view of the city, while creating a strong visual rhythm.
	11 Kim Tian Road, 2018 Landscape deck profile and treatment study 5 section, c. 2014, digital print on paper. Courtesy of National Library, Singapore. Anchored by its distinctive 36-storey twin towers, a key feature of this condominium is an elevated communal deck sitting on top of a low-rise four-storey podium. Housing communal amenities such as landscaped gardens and barbecue pavilion, the twisted sculptural form of the deck provides a sense of fluidity that blends with the green planters and helps to protect the privacy of apartments below.
c) Reflect – Negotiating spatial cultures in a global city-state This segment features seven projects from the 1990s to the 2010s ranging from national monuments to houses and public buildings, shaped by considerations of culture, heritage and the architects’ personal influences. Examples include the sensitive refurbishment of historic landmarks such as the National Museum of Singapore (2006), Victoria Theatre and Victoria Concert Hall (2014) and the creation of the new building which houses the Lee Kong Chian Natural History Museum (2015).. The refurbishment works involved restoring these buildings’ historical elements and integrating these with new contemporary designs, reflecting the buildings’ interventions and layers of history across time.
	National Museum of Singapore, 2006 Sections 1-1 and 2-2, 2003, digital print on paper and urban corridor study sketch. Courtesy of National Library, Singapore. In the refurbishment and addition of a new contemporary wing to the National Museum of Singapore, the original museum building and the contemporary interventions are intricately linked as shown in the section drawings. In addition, an urban corridor study was also carried out in envisioning the passage through the museum as part of a larger urban corridor, linking the museum to the nearby Bras Basah Park and Fort Canning Hill.
	Victoria Theatre and Victoria Concert Hall, 2014 Clocktower section, 2013, digital print on paper with ink annotations and chair as cladding elevation, 2013, digital print on paper with ink annotations. Courtesy of National Library, Singapore. An interesting aspect of the refurbishment works include turning the timber backrests of the 1950s chairs into a feature wall hanging above the theatre foyer, with their surfaces left untouched to present original seat numbers and scratch marks. Another detail is the restoration of the 1906 clock in a tower that connected the two buildings, which was sent back to the original British manufacturer, Gillett & Johnston, for restoration. A new metal cage was designed to house its counterweight mechanism and an access stair was added around it.
	Lee Kong Chian Natural History Museum, 2015 Study of future extension, 2010, pencil on butter paper and section plan. Courtesy of National Library, Singapore. Located within the National University of Singapore, the museum’s unique rock-like massing design was a result of its special requirement to protect its 500,000 natural history specimens from natural light, which meant the building had no windows except for its laboratories, office spaces and fire escape routes. Within the building, a three-storey-high atrium was carved out for the display of dinosaur fossils, while its compact form offers room for future expansion.
