The aim of this study is to clarify the space transformation of houses with raised floor in Phnom Penh, Cambodia. We conclude the result as below from the date mostly based on the field survey. Previously one family lived in one house, but now several families live in one house by making additional new space and dividing large previous house space. They can access to their houses by using vacant land space for passage or arranging stairs on several positions or sharing corridor and veranda with each other. They satisfy the needs by sharing living space and access.
