Many architecturally valuable old buildings in the world have been downgrading or being torn down for new constructions. Among them, while public buildings are somehow concerned for conservation, private houses are mostly abandoned. When these houses eventually collapse, it will be too late to preserve and difficult to restore due to lack of historical documentations. In this case, the common survey method is to mainly examine physical relics or traces at site. This kind of resource is usually limited and sometimes impossible due to no excavation authorized. In some of these houses, however, there may be original senior residents still living here for long. They can be an invaluable (or even the only) information resource of the house in the past. The question is how to help them recall memory most effectively by claimed scientific methods, not just by ordinary interviews. This paper aims to propose an implemental framework for tracing that particular sort of houses. Then it takes the No.47 Hang Bac Street house (Hanoi, Vietnam) as the case study and publishes the results here. The framework is expected applicable anywhere for that sort of houses.
