Located in the new Lusail Marina development north of Doha, this 25-story tower sits adjacent to the Arabian Gulf and includes both hotel and office components. The tower’s striking form was largely driven by sustainability concerns.

By eroding the building mass, SOM created deeply shaded areas and terraces that offer sweeping views of the Gulf. The perceived temperature on the balconies is up to five degrees Celsius cooler than the outside air. The building’s facade is sheathed with a copper screen, which permits views while dramatically reducing heat gain. All of these features combine to help reduce the building’s cooling load, a significant concern in this desert region.
