Taoyuan building project exceeds flight height limits, city orders revisions

A major commercial development in Taoyuan, Taiwan, faces significant hurdles after exceeding aviation height restrictions. The "Landmark Plaza Taoyuan Zone B," a project by Cathay Life Insurance valued at billions of dollars, was slated to receive its occupancy permit in October. However, recent measurements revealed the building surpasses the permitted height by 17 meters within a regulated flight path zone.

Taoyuan City's Department of Urban Development stated that the height restriction was part of the building permit review in 2020. At that time, the architect's design indicated a height below 60 meters, leading to the permit's issuance. The issue resurfaced in April when the Taoyuan International Airport Corporation conducted new measurements, identifying the project's location within a stricter conical surface control area and confirming the over-height violation.

In response, the city government has mandated that the developer revise the building's design to meet aviation safety standards. This process requires an environmental impact assessment and urban design review. Additionally, the supervising architect must be changed, as the original architect has passed away. If the revision necessitates it, the over-height sections will need to be demolished before construction can proceed, following approval of the revised construction plan.
