Diamond Tower, Skyscraper in coastal Jeddah, Saudi Arabia

The Diamond Tower, or Burj al-Masa, is a planned 94-storey, 432-metre supertall skyscraper in Jeddah, Saudi Arabia, designed mainly for residential use. Its faceted blue-grey glass facade is wrapped by a pale structural band carrying rows of balconies that spiral around the tower, which is to twist a full 360 degrees over its height. The first 12 floors are set aside for parking reached by ramps, and the top level is planned to hold three restaurants.

Al-Masa Tower is a planned 94-story, 432-metre supertall in Jeddah, designed mainly for residential use. Its first 12 floors are set aside for parking, with cars carried up by specially built ramps. On completion it is expected to become Saudi Arabia's second-tallest building and to twist a full 360 degrees along its height.

The name Burj al-Masa means "The Diamond Tower" in Arabic, and the building is planned to twist a full 360 degrees over its height. Its top level is designed to hold three upscale restaurants, and the first 12 floors are given over to parking reached by specially built ramps.

The tower is a planned project, not an operating building, so there are no apartments, offices or shops to visit yet. Its design puts parking on the first 12 floors, with cars carried up by specially built ramps close to each residence. The top level is planned to hold three upscale restaurants.

The facade rotates around its own axis as it rises, creating a shifting form. This movement produces a play of light and shadow that changes with the time of day and position of the sun.
