Abstract

Purpose: The Dalian Harbor Compound, a historically significant residential heritage site, faces challenges in meeting modern living standards, complicating its conservation and regeneration. Given the lack of efficient architectural survey methods in China, this study explores and applies precise and efficient technologies like laser scanning for architectural surveying, aiming to develop effective renovation strategies. Research design, data and methodology: This study breaks through traditional architectural survey methods by using 3D laser scanning point cloud data as the basic data, combined with drone tilt photography and 3D modeling technology, to establish a database of the Harbor Compound buildings. This approach clarified the situation of building deterioration and further refined and supplemented the survey and data statistical methods for this type of building. Results and Conclusions: Based on the acquired basic data from the Dalian Harbor Compound, we conducted a strategic study on the directions of local restoration and functional transformation and, according to this research direction, explored the architectural characteristics of such historically significant and valuable residential heritage buildings. A conceptual intent for the renovation of the Harbor Compound within its architectural context has been proposed.
