The 94-story tower is being developed for mixed use by the Sama Dubai company, formerly known as Dubai International Properties, part of the Dubai Holding group. The Contractor is a Joint Venture between Al-Habtoor and Al Jaber, the Architects and Engineering Consultants are Robert Matthew Johnson Marshall (RMJM), and the Cost Consultants are Hanscomb Consultants Inc. Construction began in 2005 and when completed in 2009, the tower will be Doha's tallest building and will be taller than several other proposed skyscrapers in the city.
Construction work in 2007 included advanced enabling works and tower piling. Podium piles have already been installed, while the main structure building works were scheduled to commence in the first half of 2007.
The orientation and geometry of the tower will offer magnificent views of the sea. The bold sloping roofs and angular glass facades will glow and sparkle as they capture the changing sunlight at different times of the day, and transform into illuminations of quiet elegance with shimmering reflections in the water as dusk descends.
The tower will include a 70,000 m² retail area, as well as 60 floors of serviced and unserviced apartments, 20 floors of office space, and a 235-room 5 star hotel. The tower is located in the West Bay district of Doha, next to the Doha Corniche. Estimated construction costs of Dubai Towers Doha is 2.3 billion Qatari riyal (631.9 million USD).
