The Obsidier Tower is a new landmark in the New Administrative Capital of Egypt, which is located 30 kilometers east of Cairo. This 385-meter skyscraper is a unique structure in terms of design, technology, and sustainability. It is expected to become the tallest tower in Africa and one of the tallest in the world.

The name of the tower is inspired by obsidian, which is a volcanic glass that is formed from fast-cooling lava. This material has been used throughout history to make arrowheads and other sharp tools due to its sharp edges. The tower's design is inspired by the geometric shape of a diamond and obsidian.

The Obsidier Tower is designed by the world-renowned architecture firm Skidmore, Owings & Merrill (SOM). The tower's unique shape is achieved through an innovative structural system that uses cable-strung concrete walls. This system allows the tower to have fewer columns, which increases the amount of usable space inside the building. It also helps to reduce the tower's environmental impact by minimizing the amount of concrete used in its construction.

The tower is also designed to be highly sustainable. It has a high-performance glazing system that reduces energy use by controlling the amount of sunlight that enters the building. It also has a rainwater harvesting system that collects rainwater and reuses it for irrigation and other non-potable uses within the building.

The Obsidier Tower will have 40 floors, with a total area of 116,000 square meters. It is planned to be a mixed-use development, with offices, residential units, retail spaces, and a hotel. The tower's public spaces will be located at the top of the tower, including a sky deck, observation deck, and a restaurant.

The tower is expected to become a new icon for the New Administrative Capital and a symbol of Egypt's modernization efforts. It will be a source of pride for the people of Egypt, as well as an attraction for tourists and investors from around the world.

In conclusion, The Obsidier Tower is a new landmark in the New Administrative Capital of Egypt, designed by the world-renowned architecture firm Skidmore, Owings & Merrill (SOM). It is a unique structure, with an innovative structural system, high-performance glazing system, and rainwater harvesting system that make it highly sustainable. The tower is expected to become the tallest tower in Africa and a new symbol of Egypt's modernization efforts.
