Architecture, Building and Structure Design Ju Long Plaza SCPG Incity Mixed Use by Aico Ltd Creating energetic urban public space with pedestrian friendly scale while respecting the existing urban context is the core design principle for this large scale urban complex. Designers opened up the northeast corner of the site, right cross street from Hongjialou Cathedral which is a historical landmark of the city, and dedicated it as a cultural plaza. At the center of this plaza is the renovated 100-year-old Sister House. This unique experience marks the entry point of the vibrant 24-hour leisure and entertainment district.
