ABSTRACT
This paper investigates an alternative conceptual architectural structure that serves as a seaside erosion buffer whilst also offering recreational holiday facilities for a fragile marine-based eco-system. The specific site context is Pulau Dayang Bunting in Langkawi, Malaysia, famous for its doline originated fresh water lake. The lake, located in a ‘brecciated, fault zone area of the Permian Chuping Limestone formation’, is under serious threat. Its southernmost land boundary separating it from the sea measures only three meters wide. The issue is how to strengthen it? Based on the waves’ behaviour the proposed structure will float in the sea fronting the narrow isthmus. The water currents will be dissipated and rechanneled to deposit sand on the beach side without jeorpadising the unique characteristic of the narrow lake-sea divider. If necessary, this proposed structure or segments of it may also move to another location that requires a seaside erosion prevention or rehabilitation.
