Modern architectural heritage buildings in Turkey are crucial in terms of transferring not only the cultural identity of the nations to further generations but also architectural sustainability of its distinguished period. By time, where these buildings can have constructional problems with its original structural systems, proposing a new system related with new earthquake regulations is inevitable in order to conserve them. Because most of the buildings are under threat of being demolished. The purpose of the research is to evaluate existing modern architectural heritage buildings in terms of its existing structural system and to develop a constructional model for renewal of them.

Then, the architectural plans and sections of the buildings as a data has been collected through literature survey by content analysis. At the end, the model proposal has been developed for each hotel buildings according to existing structural systems. The proposed models can be applied to sustain the life of the hotel buildings with a retrofitted structural system. So, the paper tries to conserve/protect the modern architectural heritage buildings by retrofitting its construction via presenting a remarkable study of two hotel buildings.
