Unlike most traditional buildings, Doha Tower doesn't have a central core, its service core is off-center, in this way the available interior space is maximized, in addition, a series of reinforced concrete columns in diagrid (diagonal grid) form are built adjacent to inner side of the curtain wall, to structurally support the building. These columns are canted and intersected with each other, forming the shape crosses.

Diagrid system obviates the need for traditional columns that are spreading over floor spaces, while it can effectively support buildings like traditional columns, it can be seen at the exterior of many buildings around the world, most notably, the Gherkin in London, which is also a cylindrical-shape building, the difference is that the diagrid system used on Doha Tower is placed inside the building's facade, the tower is the first skyscraper that has internal diagrid columns.

The facade of the tower comprised of two layers, the inner layer is a traditional curtain wall, while the outer layer is a intricately patterned stainless steel screen.

The facade screen is a reference to the ancient Islamic design, Mashrabiya. On the screen, a single geometric motif of different scales are overlaid along the facade, the screen is designed to shade the building from the sun, reducing the temperatures inside the building, and to shade the sand residue found on the glass of the facade. As the solar conditions is different on four directions, the densities of the motif layers overlaid on the facade is designed to be different on four sides of the building, the opacity is significantly higher on the sides facing the sun, however, when looked from a distance, the difference can't be seen at all.

Another purpose of the design of Mashrabiya is that it can protects the activities of building's occupants from being seen, while it can still offers the occupants good views from the outside.
The use of traditional Islamic design in this modern building expresses the local culture, in October 2012, Chicago based organization CTBUH (Council on Tall Buildings and Urban Habitat) awarded Doha Tower the CTBUH Skyscraper Award for Best Tall Building Worldwide.
Apart from the layered motifs, an lighting system is integrated in the facade screen, when nights come, the facade screen is enhanced with programmable light shows.
