Today we see top 10 highest buldings of the world. So lets start....................

| Burj Khalifa |
standing at 829.8 m (2,722 ft).
Construction of the Burj Khalifa began in 2004, with the exterior completed 5 years later in 2009. The primary structure is reinforced concrete.
The building was opened in 2010 as part of a new development called Downtown Dubai. It is designed to be the centrepiece of large-scale, mixed-use
development. The decision to build the building is reportedly based on the government's decision to diversify from an oil-based economy, and for
Dubai to gain international recognition.
The building was named in honour of the ruler of Abu Dhabi and president of the United Arab Emirates,
Khalifa bin Zayed Al Nahyan; Abu Dhabi and the UAE government lent Dubai money to pay its debts. The building broke numerous height records,
including its designation as the tallest tower in the world.
Burj Khalifa was designed by Adrian Smith, then of Skidmore, Owings & Merrill (SOM), whose firm designed the Willis Tower and One World Trade Center.
Hyder Consulting was chosen to be the supervising engineer with NORR Group Consultants International Limited chosen to supervise the architecture of the project. The design of Burj Khalifa is derived from patterning systems embodied in Islamic architecture, incorporating cultural and historical elements particular to the region, such as in the Great Mosque of Samarra. The Y-shaped plan is designed for residential and hotel usage. A buttressed core structural system is used to support the height of the building, and the cladding system is designed to withstand Dubai's summer temperatures. It contains a total of 57 elevators and 8 escalators.
Critical reception to Burj Khalifa has been generally positive, and the building has received many awards. However, the labour issues during
construction were controversial, since the building was built primarily by workers from South East Asia, who were allegedly treated poorly.

| Shanghai Tower |
It also has the world's highest observation deck within a building or structure (Level 121, 561.25 m),and the world's fastest elevators at a top speed of 20.5 m/s (74 kph). Designed by Gensler and owned by the Shanghai city government,
It is the tallest of the world's first triple adjacent super-tall buildings in Pudong, the other two being the Jin Mao Tower and the Shanghai World Financial Center. Its tiered construction, designed for high energy efficiency, provides nine separate zones divided between office, retail and leisure use. Construction work on the tower began in November 2008 and topped out on 3 August 2013. The exterior was completed in summer 2015. Although the building was originally scheduled to open to the public in June 2015, as of October 2016, most of the building is still closed. The observation deck was opened on 1 July 2016.

| Abraj Al Bait |
The building complex is metres away from the world's largest mosque and Islam's most sacred site, the Masjid al-Haram. The developer and contractor of the complex is the Saudi Binladin Group, the Kingdom's largest construction company.
The complex was built after the demolition of the Ajyad Fortress, the 18th-century Ottoman citadel which stood atop a hill overlooking the Grand Mosque. The destruction of the fort in 2002 by the Saudi government sparked Turkish and international outcry. It is also the most expensive building in the world. The tallest tower in the complex is the tallest building in Saudi Arabia, with a height of 581.1 metres (1,906 feet). Currently it is the fourth tallest freestanding structure in the world, surpassing Taipei 101 in Taipei, Taiwan, but shorter than the Shanghai Tower in Shanghai, China, the Tokyo Sky Tree in Tokyo, Japan and the Burj Khalifa in Dubai, United Arab Emirates. The site of the complex is located across the street to the south from an entrance to the Masjid al Haram mosque, which houses the Kaaba. To accommodate worshippers visiting the Kaaba, the Abraj Al-Bait Towers has a large prayer room capable of holding more than 10,000 people. The tallest tower in the complex also contains a five-star hotel, operated by Fairmont Hotels and Resorts, to help provide lodging for the millions of pilgrims that travel to Mecca annually to participate in the Hajj.

| Ping An Finance Centre |
The building is located within the Central Business District of Shenzhen in Futian. Its 18,931 square metre lot was purchased by Ping An Group via auction at a price of 1.6568 billion RMB on November 6, 2007.
Its foundation stone was laid on August 29, 2009 and construction started in November the same year. On March 15, 2013, the construction process was temporarily halted, due to the suspected use of concrete made with unprocessed sea sand, which could corrode the steel structure. Construction resumed on the building after sample testing.
On the morning of July 15, 2014, upon a 10-metre long steel column being lifted to place, the skyscraper exceeded 443.8 metres in height, surpassing the KK100 tower to become the tallest building in Shenzhen. The building topped out on April 30, 2015 and became the second tallest skyscraper in China at a height of 600 metres. The original plan was to add a 60-metre antenna atop the building to surpass the Shanghai Tower and become the tallest building in China. However, in February 2015, it was decided that the antenna would not top the tower due to the possibility that it might obstruct flight paths.

| Lotte World Tower |
At New Year 2016 the LED-pixels of the facade showed "2016".On March 17, 2016, prior to the final phase of external construction, the Diagrid lantern-shaped roof structure was completed. The roof structure was constructed with steel counterparts that are each 12 meters high and weigh 20 tons. The counterparts were made up of bent metal panels that are 6 cm thick, and the structure itself is 120 meters high, and it covers Floors 107–123. Approximately 3,000 tons of steel parts, a high-precision 64t tower crane, high-precision GPS alignment systems and highly skilled welding technicians were used in the construction of the roof itself.

| One World Trade Center |
The new skyscraper stands on the northwest corner of the 16-acre (6.5 ha) World Trade Center site, on the site of the original 6 World Trade Center. The building is bounded by West Street to the west, Vesey Street to the north, Fulton Street to the south, and Washington Street to the east. The building's architect was David Childs, whose firm Skidmore, Owings & Merrill (SOM) also designed the Burj Khalifa and the Willis Tower.
The construction of below-ground utility relocations, footings, and foundations for the new building began on April 27, 2006. One World Trade Center became the tallest structure in New York City on April 30, 2012, when it surpassed the height of the Empire State Building. The tower's steel structure was topped out on August 30, 2012. On May 10, 2013, the final component of the skyscraper's spire was installed, making the building, including its spire, reach a total height of 1,776 feet (541 m). Its height in feet is a deliberate reference to the year when the United States Declaration of Independence was signed.
The building opened on November 3, 2014. On March 30, 2009, the Port Authority of New York and New Jersey (PANYNJ) confirmed that the building would be officially known by its legal name of "One World Trade Center", rather than its colloquial name of "Freedom Tower". The building is 104 standard floors high, but the tower has only 94 actual stories. The new World Trade Center complex will eventually include five high-rise office buildings built along Greenwich Street, as well as the National September 11 Memorial & Museum, located just south of One World Trade Center where the original Twin Towers stood. The construction of the new building is part of an effort to memorialize and rebuild following the destruction of the original World Trade Center complex.

| Guangzhou CTF Finance Centre |
The Guangzhou CTF Finance Centre is situated on 290,000-square-foot (27,000 m2) lot along Zhujiang East Road in Zhujiang New Town, Guangzhou's central business district. In that neighborhood, the skyscraper is located east of the central axis with an underground mall and connections to public transportation underneath it.The Guangzhou CTF Centre is part of the Guangzhou Twin Towers.
The other tower of the pair, the 1,439-foot (439 m) tall Guangzhou International Finance Center, is located on the other side of the axis and is also known under the name "West Tower". The Guangzhou CTF Centre is therefore known as the "East Tower" as well. Both towers have a similar height, size, and function, and are situated close to the 1,982-foot (604 m) tall Canton Tower. The Guangzhou CTF Finance Centre is owned by Chow Tai Fook Enterprises, and houses the world's fastest elevator, which can reach speeds up to 1,200 m/min. (44.7 miles per hour (71.9 km/h).The Guangzhou CTF Finance Centre consists of a skyscraper and an eight-floor podium, that is connected to the skyscraper. The podium features a 100-foot (30 m) high atrium with a glass roof.The skyscraper is supported by a square core with sides of 105 feet (32 m) and eight concrete mega columns on the sides.

| Taipei 101 |
Its postmodernist approach to style incorporates traditional design elements and gives them modern treatments. The tower is designed to withstand typhoons and earthquakes. A multi-level shopping mall adjoining the tower houses hundreds of stores, restaurants and clubs. Fireworks launched from Taipei 101 feature prominently in international New Year's Eve broadcasts and the structure appears frequently in travel literature and international media.
Taipei 101 is primarily owned by pan-government shareholders. The name that was originally planned for the building, Taipei World Financial Center, until 2003, was derived from the name of the owner. The original name in Chinese was Taipei International Financial Center.Taipei 101 comprises 101 floors above ground, as well as 5 basement levels. It was not only the first building in the world to break the half-kilometer mark in height, but also the world's tallest building from March 2004 to 10 March 2010 As of 28 July 2011, it is still the world's largest and highest-use green building.

| Shanghai World Financial Center |
It is now the third-highest hotel in the world after the Ritz-Carlton, Hong Kong, which occupies floors 102 to 108 of the International Commerce Centre. On 14 September 2007, the skyscraper was topped out and is 492 metres (1,614.2 ft), making it the 8th tallest building in the world and the fourth tallest structure in Mainland China. The SWFC opened to the public on 28 August 2008, with its observation deck opening on 30 August.
The observation deck offers views from 474 m (1,555 ft) above ground level. The SWFC has been lauded for its design, and in 2008 it was named by architects as the year's best completed skyscraper.In 2013, the SWFC was exceeded in height by the adjacent Shanghai Tower, which is China's tallest structure as of 2016. Together, the Shanghai World Financial Center, Shanghai Tower and Jin Mao Tower form the world's first adjacent grouping of three supertall skyscrapers.
Designed by American architectural firm Kohn Pedersen Fox, the 101-storey tower was originally planned for construction in 1997, but work was temporarily interrupted by the Asian Financial Crisis in the late 1990s, and was later paused to accommodate design changes by the Mori Building Company. The building of the tower was financed by several multinational firms, including Chinese, Japanese, and Hong Kong banks, as well as by the Japanese developer and American and European investors. The American investment bank Morgan Stanley coordinated the tower's financing for Mori Building.

| International Commerce Centre |
The ICC faces the second-tallest skyscraper in Hong Kong, the 2 International Finance Centre (IFC) directly across Victoria Harbour in Central, Hong Kong Island. IFC was also developed by Sun Hung Kai Properties, along with another major Hong Kong developer, Henderson Land.The height had been scaled back from earlier plans due to regulations that did not allow buildings to be taller than the surrounding mountains.
The original proposal for this building was called Kowloon Station Phase 7 and it was designed to be 574 m (1,883 ft) tall with 102 floors. It would have risen 162 m (531 ft) over the then-current tallest in Hong Kong, 2 International Finance Centre. The building has 108 floors above ground and 4 below ground. Due to prevalence of tetraphobia in Hong Kong, floors that would have included the number "4" (4, 14, 24, etc.) were omitted. Therefore, it is marketed as a 118-storey building.
