#### *2.1. Case Study*

The south-facing curtilage (Figure 1a) was a traditional courtyard with two-story masonry–timber structure, which was located in Shengzhou City, Zhejiang Province, China, with cover an area of 685.23 m2, ridge height of 7.45 m, and gross weight of 3.65 × <sup>10</sup><sup>6</sup> kN. According to the architectural style, it was identified as being built in the late Qing Dynasty or the Republic of China. The combination of beam-lifted and Chuan-Dou frame was adopted as the load-bearing structure, and there were stone foundations and capstones under the wooden columns. The primary and secondary entrances and exits of the inner courtyard were both located in the south, the surrounding exterior walls were built with a rowlock cavity wall, and the wall foundation was stacked with rock blocks. In coordination with the emergency project of flood prevention improvements of Chengtan River within Cangyan village, the curtilage movement was planned to be conducted over a one-week period and included as follows: monolithic moving 15 m in the western direction over four days, and then 40 m in the southern direction to the new location in three days, shown in Figure 1b.

The monolithic movement of the heritage curtilage was achieved based on lifting jack technology, and the speed was set as 0.8–1.6 mm/s [3] under a horizontal pushing load provided by the push-in jack (SCLRG-100-500-T) with a rated pushing load of 1000 kN and a pushing distance of 500 mm, as shown in Figure 2a. Due to the complicated structural form and the weak structural integrity, the bottom of the masonry wall and wooden pillar were reinforced by a two-clip steel beam with block stone fillers between them to form underpinning beams. In addition, 9 longitudinal and 16 transverse H-shaped steel beams were assembled in Figure S1 (Supplementary Materials) as the integral, and the underpinning chassis was built in a grid pattern with appropriate diagonal crossing beams to enhance the horizontal stiffness The protective supporting platform was also adopted for the superstructure of the curtilage. Thereby, the vertical loads were transferred from wooden pillars and masonry walls to the steel structural chassis, and the top major structure was separated from the original foundation to form a mobile body, which was displayed in Figure 2b. The monolithic movement was achieved by the sliding movement between upper and bottom rail beams using the floating jack as the special sliding support, which could reduce the horizontal resistance and regulate vertical deformation. The upper and bottom rail beams were connected to the steel chassis and were placed on the foundation, respectively, shown in Figure 2b.
