项目所在场地的北侧和东侧有一面3米高的挡土墙，南侧临近山脊。钢筋混凝土墙伫立在平坦的地面之上，轻巧的木屋则倚墙而建。这种将底层停车场与上层居住空间通过“地上地基”分隔开来的建筑方式在该区域十分常见。它不仅巩固了上层空间，还在底层创建了可供住户进餐和运动的开放式庭院空间。

The site is an artificial construction site, has 3m retaining wall in two directions in the north and east, and has a block ridge on the south. The RC wall are erected on the flat ground and the wooden house rides on that. It is also due to the fact that the “building method” in the surrounding area separates the parking space and the living area up and down by artificial ground. In addition, the first floor piloti space is consolidated with solid foundation, and there are small yards in some places, creating spaces for lunch, exercise, and regional opening.

该住宅被设计成传统的“获得式高跷屋”，以适应非自然的人工建筑场地。这种房屋具有优良的防虫、防潮、防盗性能。由于二楼的生活空间围绕在天井花园周围，房间的采光和通风效率都得到了大幅提升。住户在通过大量窗户开口欣赏一楼美景的同时，也与喧闹的城市保持了合适的距离。

In other words, it is designed as a pure “acquired” stilt house that adapts the volume to an artificially construction site that is not an earth-derived site such as a wetland or slope that is the origin of the stilt house. The stilt type is excellent in insect proof, moisture proof and crime prevention. And because the living area on the second floor has a plan that surrounds the light garden, not only it enhances daylighting and natural ventilation efficiency, but we can also get in touch with the first floor softly. Because of acquired stilt house, it is possible to create a semi-public first floor that spreads throughout the site and a private second floor with many windows that take in landscapes, and have appropriate distance to the city.
