The residential towers, containing in excess of 4,700 residential units, were constructed in five phases during the 1990s. The majority of units are between 40 and 60 square metres. Each phase was built together with a shopping arcade. Phase 5 is also known as Tolo Place (海濤居).
The shopping centres for phases 1 to 3 are relatively small. MOSTown, formerly named Sunshine City Plaza (新港城中心), the shopping arcade built with phase 4, is by far the largest, and has retail floor space of in excess of 175,000 square metres (1,880,000 sq ft). Sunshine Bazaar (新港城廣場) is the name given to Phase 5 of the mall.
