Karachi has a collection of buildings and structures of varied architectural styles. The downtown districts of Saddar and Clifton contain early 20th-century architecture, ranging in style from the neo-classical KPT building to the Sindh High Court Building. Karachi acquired its first neo-Gothic or Indo-Gothic buildings when Frere Hall, Empress Market and St. Patrick's Cathedral were completed. The Mock Tudor architectural style was introduced in the Karachi Gymkhana and the Boat Club. Neo-Renaissance architecture was popular in the 19th century and was the architectural style for St. Joseph's Convent (1870) and the Sind Club (1883). The classical style made a comeback in the late 19th century, as seen in Lady Dufferin Hospital (1898) and the Cantt. Railway Station. While Italianate buildings remained popular, an eclectic blend termed Indo-Saracenic or Anglo-Mughal began to emerge in some locations. The local mercantile community began acquiring impressive structures. Zaibunnisa Street in the Saddar area (known as Elphinstone Street in British days) is an example where the mercantile groups adopted the Italianate and Indo-Saracenic style to demonstrate their familiarity with Western culture and their own. The Hindu Gymkhana (1925) and Mohatta Palace are examples of Mughal revival buildings. The Sindh Wildlife Conservation Building, located in Saddar, served as a Freemasonic Lodge until it was taken over by the government. There are talks of it being taken away from this custody and being renovated and the Lodge being preserved with its original woodwork and ornate wooden staircase. 
Indus Valley School of Art and Architecture is one of the prime examples of Architectural conservation and restoration where an entire Nusserwanjee building from Kharadar area of Karachi has been relocated to Clifton for adaptive reuse in an art school. The procedure involved the careful removal of each piece of timber and stone, stacked temporarily, loaded on the trucks for transportation to the Clifton site, unloaded and re-arranged according to a given layout, stone by stone, piece by piece, and completed within three months. 
Architecturally distinctive, even eccentric, buildings have sprung up throughout Karachi. Notable example of contemporary architecture include the Pakistan State Oil Headquarters building. The city has examples of modern Islamic architecture, including the Aga Khan University hospital, Masjid e Tooba, Faran Mosque, Bait-ul Mukarram Mosque, Quaid's Mausoleum, and the Textile Institute of Pakistan. One of the unique cultural elements of Karachi is that the residences, which are two- or three-story townhouses, are built with the front yard protected by a high brick wall. I. I. Chundrigar Road features a range of extremely tall buildings. The most prominent examples include the Habib Bank Plaza, PRC Towers and the MCB Tower which is the tallest skyscraper in Pakistan.
