Until 2007 it was the tallest building in the PRC, the fifth tallest in the world by roof height and the seventh tallest by pinnacle height. Along with the Oriental Pearl Tower, it is part of the Pudong skyline. Its height was surpassed on September 14, 2007 by the Shanghai World Financial Center which is next to the building.The Shanghai Tower, a 128-story building located next to these two buildings and now under construction, will be even taller.

The building is located on a 24 000 m2 plot of land near the Lujiazui metro station and was built at an estimated cost of 530 million USD.

It was designed by the Chicago office of Skidmore, Owings & Merrill. Its postmodern form, whose complexity rises as it ascends, draws on traditional Chinese architecture such as the tiered pagoda, gently stepping back to create a rhythmic pattern as it rises. Like the Petronas Towers in Malaysia, the building's proportions revolve around the number 8, associated with prosperity in Chinese culture. The 88 floors (93 if the spire floors are counted) are divided into 16 segments, each of which is 1/8 shorter than the 16-storey base. The tower is built around an octagon-shaped concrete shear wall core surrounded by 8 exterior composite supercolumns and 8 exterior steel columns. Three sets of 8 two-story high outrigger trusses connect the columns to the core at six of the floors to provide additional support.

The building has 3 main entrances to the lobby, two for the office portion and one for the hotel. Additionally, a 6-story podium at the tower base houses the Hyatt's conference and banquet facilities (first two floors) as well as a shopping mall, restaurants and nightclubs such as the hotel's "Pu-J's" on the third floor. The 3-story basement has a food court, express elevators to the observation deck, and 600 vehicle and 7,500 bicycle parking spaces below. Above, 61 elevators (supplied by Mitsubishi) and 19 escalators carry visitors throughout the building. The lower 50 floors (in the first 4 segments of the tower) are made up of 123,000 m2 of Grade A offices, divided into 5 elevator zones (3-6, 7-17, 18-29, 30-40, and 41-50). Office spaces are open-plan (column-free) with a floor-to-floor gross height of 4.0 m, net height 2.7 m. Levels 51 and 52 are mechanical floors, accessible only by service elevators.

Shanghai Grand Hyatt

The building's anchor tenant is the five-star, 555-room Shanghai Grand Hyatt hotel which occupies floors 53 to 87. It is one of the highest hotels in the world, second in Shanghai only to its sister property, the Shanghai Park Hyatt, occupying the 79th to 93rd floors of the immediately adjacent Shanghai World Financial Center. These have since been surpassed by the The Ritz-Carlton, Hong Kong, which occupies floors 102 to 118 of the International Commerce Centre. However, the tallest building to be used exclusively as a hotel is the Burj Al Arab in Dubai (excluding the taller Ryugyong Hotel which was never in use). Additionally, the world's longest laundry chute runs down the full length of the tower to the basement, and incorporates buffers to slow down the laundry during its descent.

The Hyatt's famous barrel-vaulted atrium starts at the 56th floor and extends upwards to the 87th. Lined with 28 annular corridors and staircases arrayed in a spiral, it is 27 m in diameter with a clear height of approximately 115 m. It is one of the tallest atriums in the world, the tallest being Burj Al Arab's.
