6. INSPIRATION FROM
NATURE

7. CONCEPT BEHIND THE ARCHITECTURE:-
 The design of the Sydney Opera House was inspired by nature, its forms, functions and colours.
 Utzon was influenced in his designs by bird wings, the shape and form of clouds, shells, walnuts
and palm trees.
 He looked upon nature for guidance when designing, as nature over time combined both
efficiency and beauty, hand in hand.
 His analogies cited frequently on natural forms such as the ‘palm leaf’ structure of the vaulted
shells and the idea of the ‘walnut kernel’ for the performance spaces within the shells.
 The roof structures of the Opera House are called ‘shells’. The design of the ‘shells’ was one of the
most difficult aspects of the building’s design.
 Jorn Utzon claimed that the final design of the shells, was inspired by peeling an orange. It is said
that the shells of the 14 separate roofs, form a sphere if combined.

8. ARCHITECTURAL FEATURES-

9. Site Plan

10. FACILITIES-
o Joan Sutherland Theatre: A proscenium theatre with 1,507 seats.
o Drama Theatre: A proscenium theatre with 544 seats.
o Playhouse: A non-proscenium end-stage theatre with 398 seats.
o Studio: A flexible space with 280 permanent seats.
o Utzon Room: A small multi-purpose venue for parties
o Recording Studio, etc

11. Concert Hall: With 2,679 seats, the home of the Sydney Symphony Orchestra and used by a
large number of other concert presenters.

12.  STRUCTURE-
The distinctive roof comprises sets of interlocking vaulted ‘shells’ set upon a vast terraced platform
and surrounded by the terrace areas that function as pedestrian concourse. The whole Podium is
constructed in reinforced concrete with load-bearing walls instead of columns, cellular rather than framed.
Reinforced concrete columns are generally only used to support the concrete shells or understage
structure, and are visually separated from the Podium structure.

13.  MATERIALS-
The structure of the building is made from reinforced concrete and the facades from polarized glass with
steel frames. The shells are covered by white and cream mate tiles made in Sweden, although from a
distance they all look white to the eye.
Roof shells A Three groupings of soaring curved, concrete framed roof shells, clad with white ceramic tiled
lid panels, surmounted by fine curved stainless steel lightning rails and infilled by glass walls.
Podium exterior A Massive ‘solid headland plateau’ structure supporting white tiled shell groups with
minimal external penetrations and clad in precast pink granite slabs of monumental size, including hoods
Western Colonnade protecting deeply shaded openings. Approach and ascent of Podium via
sweep of full width Monumental Steps rising from Forecourt.
Broadwalk A Flat, open and uncluttered platform paved with precast pink granite paving units,
surrounding the massive Podium ‘headland’ of the main structure on the west, north and eastern sides.
Forecourt A Broad, open and hard-paved level platform, serving as the principal land approach path to
the building and as the immediate setting for the Monumental Steps and Podium.
Lower Concourse (1988) B Sheltered access to Sydney Opera House below western edge of Forecourt,
connecting East Circular Quay with Covered Concourse and parking station, incorporating food, beverage
retail outlets, lavatories.
Covered (Vehicle) Concourse A Undercover pedestrian arrival ‘foyer’ space for those arriving by vehicle
and Lower Concourse, or to enter Stage Door. Spatial character dominated by the form of the unpainted
concrete folded beams overhead.

14. FUNCTIONALITY:-

15. o The Opera House is Sydney’s best-known landmark. It is a multipurpose performing arts facility whose
largest venue, the 2,679-seat Concert Hall, is host to symphony concerts, choir performances,
and popular music shows.
o Opera and dance performances, including ballet, take place in the Opera Theatre, which seats just over
1,500.
o There are also three theatres of different sizes and configurations for stage plays, film screenings, and
smaller musical performances. The Forecourt, on the southeastern end of the complex, is used for
outdoor performances.
o The building also houses restaurants and a professional recording studio. In 2007 the Opera House was
designated a UNESCO World Heritage site.
o It was named for Bennelong, one of two Aborigines (the other man was named Colebee) who served
as liaisons between Australia’s first British settlers and the local population. The small building where
Bennelong lived once occupied the site.
o In 1947 the resident conductor of the Sydney Symphony Orchestra, Eugene Goossens, identified the
need of Australia’s leading city for a musical facility that would be a home not only to the symphony
orchestra but also to opera and chamber music groups.

18. CIRCULATION:-

19.  Wheelchair access: Access and seating in these venues were modified to allow level access to
selected areas for patrons using a wheelchair and their companions, and two platform stair
lifts have been installed between foyer level and the Playhouse auditorium.
 Escalators: These were installed on one side of each of the staircases linking the Box Office Foyer
to the Southern Foyers of the Concert Hall and Joan Sutherland Theatre.
 Hearing and vision support: In all venues, an audio induction loop and an FM radio system have
been installed to assist patrons with hearing impairments.
 Access compliance: The realities of an ageing demographic among patrons and visitors will place
increasing demands on providing improved and more equitable access across the site.

20. AESTHETICS:-

21.  The aesthetic qualities of the Sydney Opera House relate both to its topographical setting on
Bennelong Point, and its distinctive architectural features. The place's dramatic aesthetic appeal is
enhanced by subtle floodlighting on the white roof shells at night.
 The design, form, scale and location of the Opera House make it one of the most significant
landmarks in Australia. The Sydney Opera House is significant in the course of Australia’s cultural
history, both for its place in the national history of building design and construction, as well as
the history of the performing arts in Australia.
 The Sydney Opera House represents a masterpiece of modern architectural design, engineering
and construction technology in Australia.
 It is a national icon that has become an internationally-recognised symbol of modern Australia
and of Sydney, Australia’s largest city. The Sydney Opera House is an enduring symbol of modern
Sydney and Australia, both nationally and internationally.
 The process of building the Sydney Opera House resulted in the development of a number of
innovative technical and creative solutions that were groundbreaking in the history of building
design and construction in Australia.
