Located on Xinhua Street in Huadu District, Guangzhou, the Senior Retired Officials Activity Center occupies 8,514 m² in the historic core of former Huaxian County. Responding to growing demand for public amenities, the project transforms a former parking lot into a much-needed public green space. Preserving 46 existing osmanthus trees, the design applies the “New Shan-Shui” philosophy and urban palimpsest theory. Titled “Harmony under the Moonlit Blossoms,” it uses concentric circular forms to express Mid-Autumn themes of unity and spatial continuity.
