The Uniwide Coastal Mall was envisioned in the 1990s to become the country's biggest shopping mall complex. It was built on a 10-hectare portion of MBDC's 40-hectare Central Business Park II in Parañaque City at a time when Cabangis and Rey were UHI's respective chief financial officer and controller. The mall was 90% complete and was partially operational with tenants already occupying the finished parts of the mall fronting Roxas Boulevard prior to the 1997 Asian financial crisis. The mall never formally opened as a result, and only contained few operational establishments, including GALA Bowling Club, Shakey's Pizza, Prodatanet, Jollibee, B.I.R. Parañaque, Wide Aero Av School, Uniwide Theatre and Movie Hall, McDonald's, Mang Inasal, Hyundai Showroom, Super8 Grocery Warehouse and Dunkin' Donuts. The building was then converted to a transport terminal for public utility vehicles from Batangas and Cavite. By 2006, Coastal Mall was superseded by SM Mall of Asia as the country's biggest shopping mall complex in full operation, and with the construction and opening of Parañaque Integrated Terminal Exchange in 2018 as the new transport terminal hub, Coastal Mall as a whole ceased all functions and was totally abandoned. By April 2022, the main structure was fully demolished, with the approval of the Philippine Reclamation Authority obtained by the Manila Bay Development Corporation (MBDC).
