In Hangzhou, an extraordinary residential development has drawn global curiosity for redefining what high-density living can look like. Known as Regent International, this massive S-shaped structure rises roughly 675 feet and was designed by Alicia Loo, also associated with the iconic Marina Bay Sands. Built to accommodate tens of thousands, the complex is already home to around 20,000 residents, making it one of the most densely populated residential buildings in the world.

What sets this development apart is its self-contained lifestyle. Residents have access to a wide range of amenities without ever needing to leave the building. Everyday conveniences such as grocery stores, dining options, swimming pools, and beauty services are all integrated into the structure, creating a lively, almost city-like environment under one roof. This setup has proven especially appealing to younger tenants, including students and early-career professionals, thanks in part to relatively affordable rent levels.
