A major update and expansion for Century City’s Century Plaza Hotel. Work began in March 2016. The project will remodel the 1966 hotel, scale down the number of rooms to 394 from 726 and add 63 new residences. But that’s just the start: developer Next Century associates will also add two 46-story residential towers behind the hotel, an open-air lobby, public plazas and fountains, and a massive outdoor garden that extends more than two acres. The garden will be flanked by 100,000 square feet of restaurants and retail.
