There are 2,243 units in five blocks with 18 floors in height. Currently, 10,000 people live in the complex.

The housing estate was originally built in the 1960s and named the Parker Estate (百嘉新邨; in reference to Mount Parker, south of the estate) and later sold. In 1972, the housing block was split to five blocks: the Fook Cheong Building (福昌樓), the Montane Mansion (海山樓), the Oceanic Mansion (海景樓), the Yick Cheong Building (益昌大廈), and the Yick Fat Building (益發大廈). There are shops on the street front. The highest building is the Oceanic Mansion, with 18 floors. Due to it being a composite building, it is dense.

The location is a private estate which became popular with tourists and locals after a photograph of it by Romain Jacquet-Lagrèze became viral in 2013. The photograph of the housing estate was the cover of his photo book 'Vertical Horizon'. This spot became so popular that residents have placed warning signs asking visitors to be respectful. The structure has inspired locations in films like Transformers: Age of Extinction and Ghost in the Shell and music videos like "Labyrinth" by Mondo Grosso and Hikari Mitsushima and "Cave Me In" by Gallant and Eric Nam.
