Against the backdrop of blue sky, blue sea and green trees, they are graceful, light and bright. This building has been regarded as a classic building in the world and has been recorded in history.

The appearance of the Sydney Opera House is three groups of huge shells, standing on the base of a cast-in-place reinforced concrete structure that is 186 meters long from north to south and 97 meters wide at the widest point from east to west. The first group of shells is on the west side of the lot. Four pairs of shells are arranged in series, three pairs face north and one pair faces south. Inside is a large concert hall. The second group is on the east side of the lot, roughly parallel to the first group, with the same form but slightly smaller scale. Inside is the opera hall. The third group, to the southwest of them, is the smallest, consisting of two pairs of shells, and contains the dining room. The other rooms are cleverly arranged within the plinth. The entrance to the entire building complex is at the south end, with a large step 97 meters wide. Vehicle entrance and parking are located under large steps.

The Opera House is divided into three parts: the Opera Hall, the Concert Hall and the Benilan Restaurant. The opera hall, concert hall and lounge stand side by side, built on a giant granite stone base, each composed of four towering large shell tops. These "shells" are arranged in order. The first three are covered one by one, facing the bay, and the last one is standing with its back to the bay. It looks like two groups of clams with their covers opened and placed upside down. The pointed shells of different heights are covered with white lattice glazed porcelain. Under the sunlight, when viewed from a distance, they look like upright shells and two giant white sailing ships floating on the blue sea. Therefore, It is also known as the "Sail Roof Theater". The shell-shaped pointed roof is made of 2,194 curved concrete prefabricated pieces weighing 15.3 tons each, stretched with steel cables, and covered with 1.05 million white or cream-colored ceramic tiles.
