Many historic buildings have been demolished to make way for new development in the city of Hong Kong due to immense redevelopment pressure and high land value. In particular, there are tremendous challenges for extending the scope of conservation from individual building (“Point”) & a street (“Line”) to an area/district (“Plane”). The underlying factors contribute to sustainable implementation of the Point-Line-Plane approach differ in the case for individual building conservation of individual buildings, streets and areas. Based on the literature review and international case studies, 60 factors related to the adoption of “Point”, “Line” & “Plane” approach were shortlisted and then downsized to 35 factors for a large-scale questionnaire survey in Hong Kong. With the use of factor analysis, different success criteria for delivery of the point, line, and plane heritage conservation approach were identified respectively and implications on conservation policy were discussed. This study also provides recommendations on possible incorporation of the point-line-plane approach.
