Traditional Chinese architecture is one of the major historic building types in Hong Kong. Though the documentation on traditional Chinese building structure and form is extensive, the study on the decorative components is not as abundant. The deficiency is recognized particularly in timber components due to their high vulnerability to weather and fast deterioration under natural condition. Such situation is also observed in the design of traditional Chinese timber lattices in the partition doors and windows, which are regarded as unique artistic components in the traditional Chinese architecture. The objectives of the study are set to re-discover on the design, expression and associated cultural meanings of the traditional Chinese lattices in Hong Kong and its identity in the Lingnan context. Apart from being an artistic expression with high aesthetic value, the design of the lattice patterns and features are also recognized as symbolic means for the manifestation of collective and individual aspirations and beliefs of the people. They carry the hope for fortune, peace and longevity; and the influence of traditional Chinese thinking from Confucian and Taoist can also be traced. In the traditional Lingnan architecture, Hong Kong is closely related to its context, Guangzhou style. However variations in character of the local lattice design can still be found and the identity of Hong Kong is also to be sought. A field survey on the lattice design in the graded historic Chinese architecture in Hong Kong was carried out. As there is little research reference and the sampling is limited, the objective is set to establish a procedure for the collection of data for comparative analysis. By recording the results, finding out the characters and symbolic meanings, the associated intangible cultural significance can be established. The understanding of such intangible substances will be the essence for future conservation and the conserving of authenticity will rest on the inheritance of the intangible rather than the tangible form and material. / published_or_final_version / Conservation / Master / Master of Science in Conservation
