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.
