General Electric’s $200 million permanent headquarters cleared another permitting hurdle as it received final approval from the Boston Planning and Development Agency Tuesday.

Designed by Gensler’s Boston office, the 388,070-square-foot complex will include a new 12-story, 293,300-square-foot building connected to two existing warehouses by a pedestrian bridge and ground-level plaza.

The project still is under review by state regulators under the Massachusetts Environmental Policy Act (MEPA). GE is targeting a 2018 completion date.

GE announced in January that it would relocate its global headquarters from Fairfield, Connecticut to Boston. State and city officials offered the corporation $145 million in financial incentives. GE opened its temporary headquarters in Boston in August.
