Five designers collaborate for Four Seasons Resort O'ahu at Ko Olina

The Resort Group (TRG), one of Hawai'i's largest landowners of resort developments; Westbank (WB), Canadian luxury hotel and residential developer; and Four Seasons Hotels and Resorts announced plans for Four Seasons Resort O'ahu at Ko Olina, an integrated luxury beach resort and private residences that will be part of the master-planned Ko Olina development.

Jeffrey R. Stone, TRG's founder and master developer of Ko Olina, and Westbank founder Ian Gillespie will oversee the development of Four Seasons Resort O'ahu at Ko Olina, which will encompass a re-inspired Ihilani Resort. The new resort will introduce the first Four Seasons-branded private residences in Hawai'i.

With the reacquisition of Ihilani from Cornerstone Real Estate Advisers complete, Westbank will take the development lead on Four Seasons Resort O'ahu at Ko Olina. For the renovation/conversion, Westbank assembled a design team that includes James K.M. Cheng Architects, Japanese architect Toyo Ito, Honolulu-based design firm Group 70 International, Oahu-based Philpotts Interiors and landscape architecture firm SWA Group.
