The floating house in Tempe Lake is one of the Buginese’s traditional settlements in South Sulawesi. However, the characteristic of Tempe Lake is a cistern lake, causing the lake’s water to overflow during the rainy season and dry out during the dry season. The extreme climate condition, inconsistent wind direction and waves cause constant movement of the floating house. Nevertheless, the fisherfolk community have learned to adapt to these conditions as their livelihood is largely dependent on the floating house. The aim of this research is to improve the design concept of the floating house so that it can adapt to the seasonal changes in the Tempe Lake, and determine the most suitable location and layout that will ensure the safety and durability of the floating houses, hence the sustainability of the use for the livelihood of the fisherfolk community. The research findings showed that the concept of the floating house on a raft adapts well to the seasonal changes. During high tide, the floating houses will be moved to the lake side to avoid the waves and strong winds, and also to simplify the fisherfolks’ activities. During the dry season, the floating houses will be moved afloat to the centre of the lake. The arrangement of the floating houses depends on the minimum crash distance considering the waves and the change of wind directions. The fishing boats are positioned alongside the houses to allow the house to freely move about a tether pole. The open building concept is used so that each room can be used for various purposes, including fish drying.
