Since the 2010s, virtual reality (VR) has become a vital tool for various fields, including film, television and video game, giving rise to VR imaging. With its immersive and interactive nature, VR imaging offers a unique viewing experience and has been widely adopted for cultural heritage preservation. In China, VR is increasingly used to showcase cultural heritage, providing new avenues for digital preservation and dissemination. Sai Kwan Mansion in Guangzhou exemplifies traditional Chinese residential architecture, embodying historical and cultural significance. However, rapid economic development has led to its decline, with only 100 mansions remaining, of which just ten retain preservation value. This project focuses on Sai Kwan Mansion, analyzing its history, architectural features, and conservation status through VR imaging. Using interdisciplinary methods from VR, cultural heritage, and game design, the study explores VR’s role in intangible cultural heritage preservation. It employs 360° stereoscopic VR technology and InstaVR for interactivity, allowing users to engage as “Miss Sai Kwan” and explore the mansion through guided icons and audio narratives. By leveraging VR, the project aims to document and share Sai Kwan Mansion’s cultural legacy, fostering public awareness and appreciation, particularly among younger generations. It advocates for VR’s potential in cultural heritage conservation and promotes global dissemination of Chinese architectural heritage.
