Design Guideline for Resilient Floating Housing in Tambak Lorok Coastal Settlement

Abstract

This study formulates design guidelines for resilient floating housing in Tambak Lorok, Semarang, a coastal area highly vulnerable to tidal flooding, land subsidence, and sea-level rise. Using a qualitative descriptive approach, the research identifies contextual issues through literature study, field observation, and review of relevant references, which are then synthesized into adaptive design principles. The main findings emphasize strategies for structural adaptation to fluctuating water levels, the use of sustainable materials, modular spatial systems, energy efficiency, as well as sanitation and waste management in flood-prone coastal areas. Feedback from the community indicates preferences for both floating and stilt housing types, with particular attention to materials, modular layouts, and communal infrastructure systems. The results highlight the potential of floating architecture as a flexible and sustainable adaptive solution compared to conventional approaches such as seawalls. This study contributes conceptually and practically by providing guidelines that can be applied in the planning of resilient coastal housing and replicated in other vulnerable urban coastal areas.
