One practical feature of the Thai style house is the ease with which it can be assembled or taken down. The entire house is built in light, pre-fabricated sections with each section forming a wall. Each wall is then fitted together and hung on the superstructure - a frame of wooden pillars - without nails. In former times, the fact that the house could be taken down and re-assembled with relative ease was well-suited to the indigenous way of life. When families decided to move, as they frequently did, the house would be taken down, stacked on a raft and floated down the nearest klong to a new location.
