Atkins has released plans for these huge wind turbines as part of this 240m-tall development in Bahrain.
The Surrey-based multidisciplinary practice will start construction of the turbines in April after the successful completion of a feasibility study.
The practice claims that its inclusion of the turbines into its landmark Bahrain World Trade Centre - currently under construction - is the world's first large-scale integration of its type.
According to the architect, two 50-storey sail-shaped office towers will support the three 29m-diameter 'horizontal axis' wind turbines.
The towers themselves are positioned on top of a three-storey podium, which incorporates a shopping centre, restaurants, business centres and car parking.
Atkins' head of technology, Richard Smith, said: 'With this building our client wants to demonstrate Bahrain's commitment to reducing demands on fossil-fuel energy reserves.
'The complexity of integrating large-scale wind turbines into a building is not to be underestimated, and the knowledge and experience we gain from this project can be shared with designers around the world.' by Rob Sharp
