Pearl City Mansion, Modern skyscraper in Causeway Bay, Hong Kong

Pearl City Mansion is a modern skyscraper in Causeway Bay that rises 34 floors above ground and reaches 109 meters in height. The building combines residential apartments with commercial spaces throughout its structure.

Pearl City Mansion was completed in 1971 as a 34-storey, 109 m tower at 22-36 Paterson Street. It surpassed Wing On House in Central to become the tallest building in Hong Kong, and the first in the city to rise above 100 metres. Its site, together with the neighbouring Hang Lung Centre and Regal Hongkong Hotel plots, had been the Dairy Farm milk and ice works before the 1960s.

The building shows how Hong Kong changed in the 1970s when the city had to build upward to make room for growth. Today it stands as an example of how quickly the city modernized during that period.

The tower stands at 22-36 Paterson Street, at its junction with Great George Street, a short walk from Causeway Bay station. Its podium holds the Jade & Pearl Plaza mall, whose floors are reached by lifts and escalators; the residential blocks rise above. Nearby are the Park Lane hotel, Hang Lung Centre and Fashion Walk.

The building has kept its original design concept from the 1970s, featuring clean lines and functional elements that were typical of modern architecture from that era. These features make it a visible document of that building period.
