HHHR Tower

HHHR Tower, also known as the Blue Tower, is a supertall skyscraper on Sheikh Zayed Road, Dubai, United Arab Emirates. The construction of the 72-floor, 317 m building started in 2006 and was completed in 2010. Designed by architect Al Hashemi, the building is primarily residential, with some commercial uses.

When completed in 2010, HHHR Tower was the second-tallest residential building in the world, surpassed only by Q1 in Australia, which stands 323 m tall. As of 2022, HHHR Tower is the 16th-tallest residential building in the world and the sixth-tallest residential building in Dubai. The tower comprises 454 residential apartments.

The building was built by a joint venture between Al Ahmadiah Contracting and Trading Co., from the UAE and Hip Hing Construction Co. Ltd. from Hong Kong. Another hallmark project by this team is the Masdar City in Abu Dhabi.
