Exploring the philosophy of aesthetics in Malay interior design through ornamentation and woodcarvings: a case study of Istana Tengku Long

This paper examines the philosophy of aesthetics in Malay interior architecture with a focus on ornamentation and woodcarving. Far from being mere decoration, Malay carvings are visual languages that encode religious, cultural, and ecological meanings. Grounded in the triadic philosophy of religion (Islam and tawḥīd), custom (adat and social hierarchy), and nature (tropical wisdom and environmental harmony), Malay ornamentation embody values of refinement, modesty, and continuity. Through floral, geometric, and calligraphic motifs, interior spaces in traditional Malay houses and palaces communicate cosmological ideas while also serving practical functions such as ventilation, lighting, and privacy control. The study applies this philosophical framework to Istana Tengku Long in Besut, Terengganu; a palace renowned for its refined woodcarvings and intricate interior ornamentation. By analysing the motifs, placement, and symbolic functions of carvings within the palace, the paper demonstrates how Malay interior aesthetics function as a holistic system integrating beauty, faith, social order, and environmental adaptation. Findings underscore the relevance of Malay aesthetic philosophy in contemporary heritage conservation and the need to safeguard not only the physical forms of ornamentation but also their symbolic meanings.
