Ponte City is a skyscraper in the Berea neighbourhood, just next to Hillbrow, Johannesburg, South Africa. It was built in 1975 to a height of 173 m (567.6 ft), making it the tallest residential skyscraper in Africa. The 55-story building is cylindrical, with an open centre allowing additional light into the apartments. The centre space is known as "the core" and rises above an uneven rock floor. When built, Ponte City was seen as an extremely desirable address due to its views over all of Johannesburg and its surroundings. The neon sign on top of the building is the largest sign in the southern hemisphere. It currently advertises the South African mobile phone company Vodacom.
The Nakagin Capsule Tower is a mixed-use residential and office tower designed by architect Kisho Kurokawa and located in Shimbashi, Tokyo, Japan. Completed in 1972, the building is a rare remaining example of Japanese Metabolism, an architectural movement emblematic of Japan's postwar cultural resurgence.[1] It was the world's first example of capsule architecture built for permanent and practical use. The building still exists but has fallen into disrepair. As of October 2012, around thirty of the 140 capsules remained in use as apartments, while others were used for storage or office space, or simply abandoned and allowed to deteriorate.
