Structure in General
- The diameter of the cylindrical tower is 45m.
- The building envelope consists of two layers, a metal brise-soleil with an aluminium-and-glass curtain wall behind.
- The outer layer is inspired by "mashrabiya" screens found in traditional Islamic architecture, and which serve to protect from the sun's heat and glare, and grant privacy.
- The screen serves to shade the tower from the heat, but also helps protect from sand residue forming on the glass behind it.
- The density of the screen varies depending on the orientation: 25% opacity on the north elevation, 40% on the south, 60% on the east and west.
- From a distance, the tower appears to have a uniform facade; the facade's intricacy and varied density become apparent at close quarters.
- The glass of the inner-layer curtain wall is slightly reflective so as to help reduce solar gain.
- There is a walkway between the sunscreen and inner layer to enable the curtain wall to be cleaned.
- Solar blinds are also available behind the curtain wall.
- A large atrium inside the building runs from the ground to the 27th floor, reaching a height of 112m.
- There is a restaurant at level 42 offering panoramic views of the city of Doha and the Corniche.
- At the top of the tower, at 182m, there a full-span dome housing a private residence.
- The built-in spire atop the building is a lightning rod.
- A programmed external lighting system with LEDs in the facade illuminates the tower at night.
