The condo is located in a high-rise residential building in Nanjing along the Qinhuai River, and the millennium Stone City Wall is on the north of it. The owner couple, who are about to retire, want to transform the existing standard three-beds condo into a residence suitable for retirement living. The design intentionally opens up the enclosed rooms and transforms the three-bedroom layout into one bedroom or as we can also call it: one garden. Original Linear circulation is reorganized into a looped circulation which makes one can stroll in the garden. Walking through the aisles with various functions, the framed view of the interior and exterior windows changes and enriches the sight constantly. It has the same spatial experience as living and moving in a Chinese garden. In the post-pandemic era, people spend a lot more time at home, interesting residential spaces have never been more important than they are today.
