URA-NUS GUEST LECTURE: CONSERVATION & CHANGE & SITE VISIT, 13 July 2002

Reported by Shu Charng Yen, MSIP cyshu3@singnet.com.sg

In line with the presentation of URA 2002 Heritage Awards, URA in conjunction with the NUS organised a half-day Guest Lecture entitled "Conservation and Change: Old & New" followed by a site visit to 2 of the winners of the 2002 Heritage Awards.

The morning lectures were presented by a panel of conservation experts: from the academic, practising architect, professional engineer and the developer.

CHANGE - RESPECT TO HISTORIC BUILDINGS Associate Prof Chan Yew Lih, Dept of Architecture, National University of Singapore

Prof Chan highlighted that heritage buildings are important due to its cultural significance/ Social/ Historic value; events / personalities; aesthetic value; architecture and townscape; scientific value (technological innovation).

Conservation refers to all the processes employed in keeping a place alive and ensuring continuity. Authenticity in conservation is important as architectural heritage is irreplaceable so that they can be passed onto our future generations.

Notwithstanding, there is a need for change due to obsolescence of historic building, be it:

1. Functional: not able to meet the new functional requirements of the original use
2. economical : most historic building occupy prime site
3. contextural : its original use has become inappropriate due to the change of use and pattern of the area.

Due to the pressure for demolition, Singapore has lost many heritage buildings such as the KK Market and former YMCA. Hence, there is a need for innovative conservation for the following reasons:

1. To bring a historic building to a stage of relevance;
2. To manage change and still retain cultural significance;
3. To ensure genuine continuity of the place.

Prof Chan drew examples of adaptive re-use of a heritage building with new buildings within its site. Foreign examples shown included (The recommended websites are added by the author for readers who may wish view images of the buildings):

  1. Exchange Building (1903, Berlage), now Amsterdam Cultural Exchange http://www.beursvanberlage.net/zalenverhuur_eng/
  2. Guggenheim Museum Extension (New York) by Gwathmey Seigel http://www.gwathmey-siegel.com/projects/architecture/cultural_projects/gugg/indexright.html
  3. The Pyramid at the Louvre (Paris) by IM Pei http://www.greatbuildings.com/buildings/Pyramide_du_Louvre.html
  4. Tai Po Railway Station (Hongkong) now Railway Museum
  5. Cheong Fatt Tze Mansion (Penang) now a Boutique Hotel www.cheongfatttzemansion.com
  6. Gare d' Orsay (Paris) former railway station now Museum http://www.aviewoncities.com/paris/garedorsay.htm www.musee-orsay.fr
  7. Castle Vecchio (Carlo Scarpa) Italy, now a Museum
  8. Commercial Building, Frankfurt
  9. "Dancing Building" , Prague (Frank Gehry corner at the Jiraskuv Bridge. Officially named the 'Rasin Building,' soon after its conception it was dubbed 'Ginger and Fred,' as it dances like the famous couple Rogers and Astaire around the corner. The building definitely pinpoints some directions modern architecture can take when faced with a city that demands either 'restauration' architecture or 'new' architecture. http://lava.ds.arch.tue.nl/gallery/praha/tgehry.html
  10. Hubertus House (Aldo van Eyck) Amsterdam http://www.greatbuildings.com/buildings/Hubertus_House.html
  11. British Museum & the extension by Norman Foster, London: the addition of a Glass Court http://www.greatbuildings.com/buildings/The_British_Museum.htm
  12. Reichstag, Berlin : the addition of a glass dome as a modern expression & technology to enhance the buiulding in its new function of a rooftop viewing gallery. http://berlin1.btm.de/infopool/jsp/e_b_002_reichstag.jsp
  13. Extension to the York Theatre: the interpretation of historic arches in the new lobby
Some of these examples attempted to show the new buildings are distinct from the old. Others utilised the architectural language of rhythm but all did not make any attempt at imitating the heritage building.

Prof Chan ended her presentation by recapitulating on the need to ensure proper documentation by the authorities, the need to handle change innovatively and to make the intervention reversible. She added conservation should leave behind a cultural heritage not to be dismissed by posterity as lacking in authenticity.

BEYOND CONSERVATION Ms Wo Mei Lan, Director, Liu & Wo Architects Pte Ltd

Ms Wo presented a first-hand account of a restoration architect who is also the consultant to the restoration and addition of a new 4-storey to a residential development (The Lotus) one of the winners of the 2002 URA Heritage Awards.

Ms Wo introduced 6 restoration projects:
  1. 3-storey shophouse at Mohd Sultan, River Valley which is converted into commercial use on the 1st storey and residential (4 studio units) on the upper floors
  2. 2-storey single residence at Neil Road
  3. Ten units of shophouse converted into a boutique hotel of 79 guest rooms)The Royal Peacock) at Keong Saik Road
  4. Envelop-control site with redevelopment into a shophouse façade comprising 3 units and 29 guestrooms (Keong Saik Hotel)
  5. 3 units of shophouses converted into a boutique hotel of 42 guestrooms (Chinatown Hotel)
  6. The Lotus: 18 units of dwelling houses with a rear entrance facing the communal facilities sandwiched between the new 4-storey block and the conservation houses.
Ms Wo proposed that it is possible to have creative adaptive re-use and that conservation ideals and economic goals can coexist in harmony. She cited the above examples of conversion of shophouses into boutique hotels and residential-commercial use as viable adaptive re-uses.

CONSERVATION - THE ENGINEERING APPROACH Er. Lee Tuck Cheong, Technical Director, Maunsell Consultants (S) Pte Ltd

Maunsell Consultants was the Consulting Engineer for the 2 buildings which won the URA Heritage Awards, namely, The Fullerton Hotel (2001 URA Heritage Award) and the Sun Yat Sen Villa (2002 URA Heritage Award) Er Lee mentioned that for new construction, RITA appraoch was used but for conservation buildings an additional "S" was added, i.e., strengthening of existing structural members:
R : Research
- History, Construction : Basic Structural Form
- Documents : "As-built" drawings, calculations
- Sources: Building & Construction Authority (BCA), National Archives
     
I : Investigation
- Site: geological formation study, trial holes, foundation exploration, underground constraints (existing MRT, sewer, etc)
- distribution of boulder clay formation as in the Fullerton Building and MRT reserve line underneath the Sun Yat Sen villa Annex
- Building Measurement Survey (draw up existing Structural Plan) - Reinforcement Steel Survey
- Building Condition Survey
:
T : Testings
- Sub-Structure : Soil Testing, ground water testing
- Superstructure : Non-destruction testing: concrete compression, ultrasonic pulse velocity tests (UPV); carbonation tests; reinforcement tensile tests
- Actual load tests (working load only)
:
A : AnalysisInput
(Results of Investigations & Testings) Þ Process (Engineering Break-Analysis - Computer Modelling Technique) Þ Output (Structural Capacity of Building)

For the Fullerton Building, such findings is important to ascertain the new loading of the new Ballroom
S : Strengthening
New Floor Layout : Identify New Elements and Existing Elements that need strengthening New Structural Plan

For the Fullerton Building, Raft and beam strengthening was carried out. A total of 193 beams (50%) and 160 columns (80%) were strengthened.

For the Sun Yat Sen Villa, bracing and propping of the external structural was carried out.
CONSERVATION - A DEVELOPER'S PERSPECTIVE
Mr. Daniel Teo, Chairman & Managing Director, Hong How Group


Mr Teo started by reminiscing lost heritage such as Eu Villa, Meyer Chambers, Amber Chambers and listed heritage which are now being protected in Singapore such as Stanford Building, House @ Meyer Place, House of Tan Yeok Nee (now Chicago School of Business), CHIJMS, Victoria Concert Hall, Supreme Court and Goodwood Park Hotel.
  1. He shared his experience on 4 conservation projects in River Valley: No 3 Kim Yam Road : a 3-storey terrace house with extension within the building profile
  2. No 11 Kim Yam Road: a 3-storey terrace house with extension within the building profile
  3. Nos 287, 289 River Valley Road: two 2-storey terrace houses with a 4-storey rear extension
  4. No 338E River Valley Road: 2 units of identical-looking bungalows of which the rear bungalow was demolished to allow redevelopment of a new building in view of the yet to be gazette of River Valley as a conservation zone.
It is noted that URA subsequently allowed the demolition of the narrow front gates at No 11 Kim Yam Road to allow car park at the front which set the precedent for No 3 to be allowed so accordingly.

His current project is at Armenian St/ Loke Yew St which is proposed as a boutique hotel/ lifestyle store.

Mr Teo ended his presentation by outlining the following points for the authorities to consider:

1. Transferable Plot Ratio
2. Property Tax Concession
3. Exemption of Development Charge
4. Encouragement of Soho Concept by Exemption of Conversion charges
5. Clarification of the Purpose of Road Widening Line
6. Back Land issue
7. Fire Safety Bureau considerations
CONCLUSION

The Guest Lectures were thought-provoking in that it poses questions to what extent the authorities' would allow in terms of envelop-control guidelines to achieve greater architectural expression of the old v new, and hence, the attendant guidelines to complement the new thinking. We have seen how Assoc Prof Chan's inspirational foreign examples and how this can breathe a new fresh of new ideas into the architectural language to be used in the integration of old v new. On the other hand, to what extent will the authorities allow a diversity of voices in this whole Remaking of Singapore to create a place where all Singaporeans belong and be rooted. Will the new Conservation Advisory Panel fall into this role???


On the part of the practising architects, from what we have seen, many of our new buildings or extensions to heritage buildings not particularly experimental, from the Raffles Hotel extension (which is a reproduction of the historic monument itself) to the ubiquitous shophouse with extensions to the rear. The "safest" solution is to imitate, of course, we have reached a stage where our local architecture can stamp its unique identity in our quest to be a great city, a global City of Distinction.

Of course, it is fair to say that Singapore may not have many opportunities to do large-scale conservation and extension projects as in the British Museum, Reichstag, Guggenheim. We only have the humble shophouse.

In view that the authorities are now working out in detail the Identity Plan, there could be more opportunities for daring, bold, experimental, innovative architecture that marries the old and new. Furthermore, we still have Victoria Theatre and Concert Hall, the Museums, and even heritage buildings are undergoing evolution. Even some of our newer buildings will eventually become heritage buildings in time to come. Although we may not have many opportunities, we still have some opportunities to create such exciting marriage of old and new architecture in time to come
