Architectural plans of a property development that is blamed for causing structural damage to French colonial-era buildings on Phnom Penh’s Sisowath Quay show drawings of a five-story residential building, complete with underground car parking. According to the plans, dated July 11, the mysterious company behind the development is called Sam Ang Vattanac Company. Chhun Leang, co-found and president of Vattanac Bank, which is part of a family-run group of businesses that includes Vattanac Properties, has denied that her firm is involved in the Sisowath Quay development. Ms Leang has said that the project is the responsibility of an individual whom she declined to identify. The director of the firm’s Vattanac Properties is one Sam Ang Vattanac, who is the son of Ms. Leang.
