The Pentominium is a 122-storey, 516 m (1,693 ft) supertall skyscraper on hold in Dubai, United Arab Emirates. Construction on the tower has been halted since August 2011. [1] It was designed by Andrew Bromberg of architects Aedas [6] [7] and funded by Trident International Holdings. The AED 1.46 billion (US$400 million) construction contract was awarded to Arabian Construction Company (ACC). [8] The Pentominium has one of the deepest excavations done in the world.


Construction started on 26 July 2008 and, before construction stopped, the building was expected to be completed in 2013. [5] By May 2011, 22 floors had been completed. However, in August 2011, construction stopped after Trident International Holdings fell behind on payments for a US$20.4 million loan following the global financial crisis. [9] As of 2019, the tower still stands incomplete.

Had the project been completed as scheduled, the Pentominium would be the second tallest building in Dubai after Burj Khalifa as well as the tallest residential building in the world if completed before World One.

Projected residential height

The Pentominium would have been the tallest all-residential building in the world instead of the 432 Park Avenue upon completion if construction had resumed; it has the highest projected height of any residential building under construction. [5] It has been described as "one of the most architecturally significant projects in the city currently under construction" due to the "large number of offset cantilevered spa gardens and apartments down one side which create an imbalance for the building and, as a result, some fairly significant building sways which have to be corrected during construction." [10]

The project management contract was awarded to the project management firm Precipio. [11]

Apartments and design

The word "pentominium" is a portmanteau of the words "penthouse" and "condominium". [12] Each residential floor will have just one 4-bedroom apartment of over 600 m2 (6,500 sq ft). [12] [13] Amenities available to residents would include a swimming pool, an observation deck, a private cinema, a health club and a banqueting hall, along with a cigar lounge and a business centre.
