With the development of parametric design in architecture and structural engineering, parametric design has been applicated in many complex skyscrapers or large-span structures. It can also be used in traditional projects such as Chinese villa. The application of parametric design on Chinese villa has been developed with the back ground of Linyi Aozhen Graceland. The technic includes the processes of building standard parametric structural model, locating and assembling each villa unit, fixing the boundaries of adjacent villa units, generating YJK model and drafts. The technic can improve the efficiency of the design process of low-density villa projects greatly.
