With the construction of the urban-rural integration, Chinese township's structure begins to adjust. The changes of the site layout planning of rural schools bring a large number of vacant rural school buildings. This paper aims to study the possibility and rationality about the rural school building reuse in northwest China. The appropriate retrofitted buildings types are public buildings such as culture building, medical building or welfare building. The construction method is proposed which includes the repair, replacement and increase. Finally, the example that the rural school building transformed into the disabled care center proves the possibility and rationality about the renovation patterns. The use of this kind of renovation patterns will save construction costs, bring economic benefits and a good social effect.
