Courtyard No.3 faces south and is a typical parallel main-and-cross courtyard complex of the Taishun family. The main courtyard has a width of five bays, while the cross courtyard has three bays. The architectural sequence along the central axis of the main courtyard is as follows: the inverted seat (locally called the street house) → the first courtyard → the living room (with the first and second doors, the second courtyard, and the main house). The total depth is approximately 52 meters. The cross courtyard does not have a second door, and the first courtyard lacks side rooms, while the second courtyard has single-sided side rooms. The entire courtyard complex has a total width of eight bays, which is less than 24 meters. The inverted seat of the main courtyard is two stories high, with the eastern end room serving as the main entrance. The side rooms (three bays each) and the living room are all single-story. The first courtyard has luxurious interior and exterior eaves decorations, with corridors on all four sides. The main house has eaves columns that reach the ground, while the other buildings have cantilevered eaves corridors. The living room in the main cross courtyard has a door on the corridor wall for interconnection.
