The world’s tallest tower at one-mile long or 1,600 m is planned for Jeddah by the Kingdom Holding Company (KHC), according to latest news reports.

This would make it twice as tall as the Burj Dubai, which is under construction.
Tenders for the major construction packages for the Mile High Tower, as it is known, are expected by June this year, following a final investment decision on the project, according to recent reports in Meed.
While the final height and number of storeys are yet to be finalised, the tower is likely to be part of the Jeddah Project, and is expected to cost in excess of $10 billion.
The masterplan for the Jeddah Project was prepared by Pickard Chilton, according to KHC’s website. KHC has also appointed Bechtel to supervise and develop the Jeddah Project. 
Located in the city’s northern area on the Red Sea coastline, the Jeddah project has an area of 5.3 million sq m.
“The investment value of the (Jeddah) project is estimated at SR50 billion upon completion, comprising of a colossal skyscraper with a surrounding area for other facilities (residential, commercial, construction of a five-star hotel and offices),” says KHC’s website.
“The residential area will be 1.5 million sq m, the commercial area will be 470,000 sq m, education vicinity will have an area of 150,000 sq m and the offices area will be 800,000 sq m. The remaining area will be utilised for leisure facilities, tourism and the construction of four-star hotels,” the website adds.
According to the Meed report, UK’s Hyder Consulting is working in a joint venture with Arup, also of the UK, as engineer on the project.
Saudi firm Omrania is the project architect and is working in a consortium including Pickard Chilton, which prepared the concept designs.
The tower plot will be 170,000 sq m and, according to Meed, Omrania has spoken to wind consultants and lift manufacturers to deal with the logistical challenge of transporting elevator passengers to such a height.
US-based Pickard Chilton’s website provides details for a Mile High tower in Asia. According to the firm, the Mile High Tower proposes a lighter, dynamic structural system that actively responds to forces placed upon it. Controlled by wind-detecting sensors, stabilising aileron-like fins run the length of the tower frame and modulate their position to control resonant motion and building drift.
The separation of the structural frame and the building envelope enhances the quality of the interior space by providing an abundance of natural light and ventilation. Equipped with wind generators, photovoltaic panels, a heliostat, and sewage treatment facilities, the tower attains a high degree of sustainability with minimal environmental impact.
