Khanqah of Sultan Ibrahim Khorrambid is a unique relic of the Timurid period. This building has exquisite stucco decorations, combined stone and tile decorations, and mosaic tiles. The building has a central domed chamber (gonbadkhaneh), the dome of which almost completely collapsed due to the earthquake and only a small part of it remains. Considering the climatic conditions, public expectations, and the need to preserve the decorative elements, reconstruction of the dome is deemed necessary. In the reconstruction of the dome, there are obstacles such as the weakness of the existing structure, the type of structure to be reconstructed, and the style of the dome. In this study, three methods for reconstructing the dome have been proposed: constructing the dome with bricks and implementing a wooden ring in the arch, implementing a combined metal and brick structure, and implementing the dome with a wooden structure. Considering that a small volume of the dome remains and on the other hand, preserving the decorations is important, implementing the dome with a light structure (the last case) is suggested.
