The Pentominium was a planned 122-storey, 517 m (1,696 ft) supertall skyscraper located in Dubai, United Arab Emirates. Construction on the tower was halted in August 2011. It was designed by Andrew Bromberg of architects Aedas and funded by Trident International Holdings. The AED 1.46 billion (US$400 million) construction contract was awarded to Arabian Construction Company (ACC).

Construction started on 26 July 2008. Before construction stopped, the building was expected to be completed in 2013. 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. As of 2023, the tower still stood incomplete.

In December 2023, Select Group acquired the long-stalled Pentominium Tower, which was renamed Six Senses Residences Dubai Marina in March 2024. The company plans to resume its construction with a return design from 2007 in May 2024.

Had the project been completed as scheduled, the Pentominium would have been the second tallest building in Dubai after Burj Khalifa and the tallest residential building in the world, surpassing the 472.4-metre (1,550 ft) Central Park Tower in New York City.

Projected residential height

The Pentominium would have been the tallest all-residential building in the world instead of the Central Park Tower upon completion if construction had resumed; it has the highest projected height of any residential building under construction. 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."

The project management contract was awarded to the project management firm Precipio.

Apartments and design

The word "pentominium" is a portmanteau of the words "penthouse" and "condominium". Each residential floor would have had just one 4-bedroom apartment of over 600 m (6,500 sq ft). 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.
