Jean Nouvel may be one of the world’s most famous architects, but it will be the city’s chief planner — currently Amanda Burden — who will have the final say over the design of a soaring luxury tower next to the Museum of Modern Art.

The City Planning Commission is requiring that a completed design would have to be approved by the commission’s chair before a building permit can be issued.

The commission approved the tower with several changes, the most significant being lowering its height from a proposed 1,250 feet — about as tall as the Empire State Building without the antenna — to 1,050.

Final approval was granted by the City Council this week.
