Opera house vs Doha Tower

Informations

The Sydney Opera House is a multi-venue performing arts Center at Sydney Harbour in Sydney, New South Wales, Australia.

It is among the 20th century's most famous and distinctive buildings.Designed by Danish architect Jørn Utzon, but completed by an Australian architectural group headed up by Peter Hall, the building was officially opened on 20 October 1973 after a gestation beginning with Utzon's 1957 choice as winner of an international design competition. The Government of New South Wales, led by the premier, Joseph Cahill, authorised work to start in 1958 with Utzon directing construction. The government's decision to construct Utzon's design is often overshadowed by conditions that followed, including cost and scheduling overruns as well as the architect's ultimate resignation.The building and its surrounds occupy all of Bennelong Point on Sydney Harbour, between Sydney Cove and Farm Cove, adjacent to the Sydney central business district and the Royal Botanic Gardens, and close by the Sydney Harbour Bridge. The construction comprises multiple performance venues, which together host well over 1,500 performances annually, attended by over 1.



2 million people. Performances are presented by numerous performing artists, including three resident companies: Opera Australia, the Sydney Theatre Company and the Sydney Symphony Orchestra. As one of the most popular visitor attractions in Australia, the website is visited by over eight million people annually, and approximately 350,000 visitors take a guided tour of the building each year. The building is managed by the Sydney Opera House Trust, an agency of the New South Wales State Government. On 28 June 2007, the Sydney Opera House became a UNESCO World Heritage Site, having been listed on the (now defunct) Register of the National Estate since 1980, the National Trust of Australia register since 1983, the City of Sydney Heritage Inventory since 2000, the New South Wales State Heritage Register since 2003, and the Australian National Heritage List as 2005. Moreover, the Opera House was a finalist at the New7Wonders of Earth campaign list.

Burj Doha, also known as Doha Tower (Arabic: ??? ????) and formerly called Burj Qatar and Doha High Rise Office Building, is an iconic high rise tower located in West Bay, Doha, Qatar. On October 18, 2012, the building received the CTBUH Skyscraper Award for the Greatest Tall Building Worldwide in the CTBUH. The $125-million office building, designed by French architect Jean Nouvel, has a height of 238 metres (781 feet ), with 46 stories. In 2004 the project was named as High Rise Office Building and after completion of construction in 2012 was branded as Burj Doha by the owner, H. E. Sheikh Saud bin Muhammed Al Thani. The public has noticed the building's'phallic form', no matter what Nouvel calls a'fully assumed virility. 'Doha Tower comprises 46 floors above floor, three floors below ground and a total gross floor area of approximately 110,000 m². It has no central core, leaving more inner space accessible to its occupants. The design is unique, the first skyscraper with inner reinforced concrete diagrid columns, which form a cross (X) shape that joins with the eye cylindrical facade. The design expresses the local culture, connecting the very contemporary with ancient Islamic designs (Mashrabiya). Islamic screens were designed to shade the building from high temperatures as well as the unpleasant sand residue found on glass throughout the area. The building is designed to hold offices for companies wishing to operate in the diverse business district of West Bay. Doha Tower is owned by Sheikh Saud bin Muhammed Al Thani and operated by Hamad Bin Saoud Group. It is now the sixth tallest building in Doha.
