In 1957 an international design competition for the new Opera House in Sydney was won by Danish architect Jørn Utzon. The unique location on the Benne Long Point in the middle of Sydney Harbour, where the building might come, inspired Utzon's relatively young for a building in profile looked like a fleet of sailboats. Utzon Opera House wanted a 'modern Gothic cathedral' creation. In 1958 has started the construction of the Opera.
The building consists of a plateau where two amphitheaters are saved. Above these theaters raise large white scales that resemble billowing sails. The design of this construction proved much easier than building it.
The biggest problem was the shape of the scales that were not geometric, and are not repeated in a fixed pattern. This problem was solved when Utzon had the idea to cut different scales from a single bulb. He probably came to this idea when he saw to his son an orange peel. A virtual sphere with a diameter of 75 meters which became the figure of the scales was derived.
The roof consists of main dishes, side dishes and bowls ventilation. The bowls are poured on the site and are constructed from prefabricated ribs with cables were strung together and then were compressed into a bow. In the space between the ribs are prefabricated ceramic lids placed back covered with more than one million tiles. Matt and glossy tiles are then placed in an alternating pattern, so that the scales have been a lively atmosphere and the building white and various shades of gray as the response to changes in the daylight.
The pointed arches of the scales are derived from different heights and overlap. The highest peak is about 54.5 meters high arch.
The Opera House was built in three phases. First the shelves when the scales and eventually the cladding and the glass walls. Utzon wrote two books containing ideas about the underlying architecture of the building, Red Book (1958) and Yellow Book (1962).
The third phase Utzon unfortunately they could lead. This phase came to because when a new government came in New South Wales in 1964 Utzon was severely criticized by the government and was no longer paid. In 1966 he found himself forced to leave Australia with his family. The third phase was then completed under the direction of Peter Hall, Lionel Todd and Littlemore DS.
When entering the building, visitors first find themselves in the simple space under the stairs, which are completed with concrete beams. Via this a staircase leads to the great plateau. Side aisles are rising through the foyers and bars on the north side connected with the foyer on the south side. There is also a concert hall which is covered with birch veneer and a traditional opera house design.
In 1973 the Opera House opened by Queen Elizabeth. She compared the arches of the building with the pyramids in Egypt, also controversial, but now is seen as a world wonder. The Sydney Opera House will eventually be seen in its world as a miracle. In any case, has become the architectural symbol of the city of Sydney.
