- Concrete
The bulk of the Sydney Opera House is made of reinforced concrete, with over 1,000,000 individual tiles covering its exterior. This material was chosen because it is strong, durable, and relatively easy to work with.
- Glass
The Sydney Opera House is known for its distinctive glass walls. These walls were made using a special type of glass called "float glass," which is produced by floating molten glass on a bed of molten tin. This process results in a glass that is extremely flat and free of imperfections.
- Steel
Steel was used for the structural framework of the Sydney Opera House. This material is strong and lightweight, making it ideal for use in a building with such a large roof structure.
- Timber
Timber was used for the interior of the Sydney Opera House, including the floors, walls, and ceiling. This material was chosen because of its warmth and natural beauty.
- Ceramic Tiles
The Sydney Opera House is covered with over 1,000,000 ceramic tiles. These tiles were made from clay that was fired at a high temperature, making them extremely durable. The tiles were also glazed in various colors, which reflects sunlight and gives the building its unique appearance.
