There are direct efforts from the Egyptian government to bring to life the glory of the khedive Era through the restoration and retrofitting of the khedive heritage buildings. In this context this research will cover the efforts to retrofitting and reallocate the spatial activities of the Al-Tahrir complex. The study will spot light on one of the attempts to reuse the Al-Tahrir complex as a recreational complex building that includes hotels, conference halls and a mall. A preliminary architectural design plans, and 3d model will be demonstrated in the study to show the efforts done to enliven this complex building, which is one of the famous buildings of the khedive architecture.Adding a mass to a heritage building must be done wisely without hiding the main original building. And it can be done through the double skin façade way using the glass material.
