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

- Castle Vecchio (Carlo
Scarpa) Italy, now a Museum
- Commercial Building,
Frankfurt
- "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

van Eyck) Amsterdam http://www.greatbuildings.com/buildings/Hubertus_House.html
- British Museum &
the extension by Norman Foster, London: the addition of a Glass
Court http://www.greatbuildings.com/buildings/The_British_Museum.htm
- 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
- 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: |
- 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-storey single residence
at Neil Road
- Ten units of shophouse
converted into a boutique hotel of 79 guest rooms)The Royal Peacock)
at Keong Saik Road
- Envelop-control site
with redevelopment into a shophouse façade comprising 3 units
and 29 guestrooms (Keong Saik Hotel)
- 3 units of shophouses
converted into a boutique hotel of 42 guestrooms (Chinatown Hotel)
- 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: |

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

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. |
- 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
- No 11 Kim Yam Road:
a 3-storey terrace house with extension within the building profile
- Nos 287, 289 River
Valley Road: two 2-storey terrace houses with a 4-storey rear
extension
- 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. |
