Treon Seongsu is a premier redevelopment in Seongsu Strategic Zone 3, offering unobstructed, south-facing views of the Han River. A linear three-tower layout ensures river views from all residences, while carefully arranged building masses create open view corridors that refine the riverfront skyline. The project uniquely features a 30,000㎡ Grand Garden, extending the waterfront park between Seoul Forest and Ttukseom Hangang Park, and delivering a rare dual premium of Han River and park views. With private elevators, three-sided open units, and resort-style amenities including a sky lounge, river-view fitness center, and infinity pool, Treon Seongsu sets a new benchmark for luxury living in Seongsu.
