Building is a relatively permanent enclosed construction over a plot of land, having a roof and usually windows and often more than one level, used for any of a wide variety of activities, as living, entertaining, or manufacturing. This is an art or business of assembling materials into a structure. Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, and aesthetic reasons. Tall building is anything that ‘breaks the existing skyline and/or is significantly taller than the surrounding built form’. Here is the list of Tallest 10 Buildings in the world

1.Burj Khalifa

Burj Khalifa is the Tallest building in the world. Dubai is recognised as a home to Burj Khalifa and other megastructures. The Burj Khalifa has broken so many world records standing at 828m (2,716.5 ft.) above ground. It has the highest number of stories in the world (over 163), which includes the world’s highest outdoor observation deck and the highest occupied floor in the world. The elevators operating in the tower are the tallest service elevators in the world running at the longest travel distance. It is the highest outdoor observation deck in the world, has the elevator with longest travel distance in the world. The Burj Khalifa is crowned as one of the most elite and highly coveted residential places in the world. It is the tallest free standing structure in the world. It is the highest occupied floor in the world. It is the second highest swimming pool in the world (76th floor). Totally 54 working elevators traveling 40 miles per hour. The cost of the Burj Khalifa is USD $1.5 billion.

Burj Khalifa was designed by Adrian Smith and the architecture firm of Skidmore, Owings & Merrill in collaboration with Samsung C&T Corporation. It is also a top tourist attraction in Dubai. Burj Khalifa is one of the best spots to watch sunsets in Dubai. This towering skyscraper lies in the heart of Downtown, a district commonly referred to as the ‘Centre of Now‘. People flock here from around the globe to witness the exciting celebrations, fountain shows and fireworks. The concept behind the development by His Highness Sheikh Mohammed Bin Rashid Al Maktoum was to build on Dubai’s ever-growing status as a popular tourist destination, with this skyscraper adding to that vision. It’s three times as tall as the Eiffel Tower and nearly twice as tall as the Empire State Building. Burj Khalifa and Downtown Dubai itself are developed by Emaar Properties. Excavation beginning on 6th January 2004, the tower was completed and opened to the public on 4th January 2010. It was inspired by the spider lily flower. As a first precaution, the tower was built in a Y-shape to make it more stable.

2.Shanghai Tower

Shanghai Tower is located in Shanghai, China. It surpassed the second tallest building in the world. 632-metre high Shanghai Tower, designed by Gensler. The Shanghai Tower is a masterful piece of civil and environmental engineering. It is one of the world’s most impressive architectural marvels. The project started in November 2008 and Opened to the public in 2016. It’s cost is around £1.5 billion. The Chinese government has described this building as ‘a symbol of a nation. We were given rare access to this new addition to the building just before completion in the company of Gensler’s managing principal, Daniel Winey and Xia Jun, Shanghai Tower’s design leader and a star in the Chinese architectural firmament. Shanghai Tower is designed to embrace and stimulate the life of the city. Yet, instead of parks spread horizontally across the city, the tower provides gathering spaces stacked vertically. Within 127 stories, Shanghai Tower houses Class A office space, entertainment venues, retail, a conference center, a luxury hotel, and cultural amenity spaces. By emphasizing public space and locating shops, restaurants and urban amenities at the atrium levels, Shanghai Tower provides a new experience for living and working in super tall towers. It has the tallest and fastest lifts travelling at 40mph to almost the full height of the tower: that’s 580 metres in 32 seconds.

The ground floor becomes an ‘open market’ linked to the subway network. The glass has been designed to minimize reflected light, so that people inside can see out over Shanghai. With car parking below ground, the first five stories above ground comprise the commercial retail podium. The building is separated into nine zones, each separated by public sky lobbies. These 12 or 15 storey-height voids are formed within the twisting space between the external glazing and the structural core. The floors of these lobbies extend out to the curtain wall and therefore close each volume off from the one above and below. Each sky lobby is landscaped with a mixture of semi mature trees and local varieties of shrubs in planters. With these sky gardens acting like Trombe walls, there is no requirement for heating or mechanical ventilation in these airy spaces. The building is designed to withstand an earthquake of up to 7.5 on the Richter scale with the help of the world’s largest tuned mass damper. Other energy-saving devices are there in this LEED Gold building range from geothermal heat sources to gas-fired co-generation. While most of the tower’s energy will be provided by conventional generating systems, a bank of 270 wind turbines at the top of the tower should create around 350,000 kWh per year. It is sited adjacent to the neighboring Jin Mao Tower.
