Preservation is usually considered as an endeavor to carefully protect history, the object of preservation being viewed as a treasure that cannot be touched. When a building is damaged, architects try to conserve the authenticity of the historical by rebuilding exactly what used to be there. But how do we deal with Preservation beyond restoring a seemingly historical condition? How do we preserve beyond the physical? How do we preserve the essence of a building, its human dimension and engage in a new environment? Just like renaissance architects considered the human body as the measure of all things, this project deals with damaged buildings as amputated human bodies in need of a Prosthetic Implant. Prosthesis /prɒsˈθiːsɪs,ˈprɒsθɪˌsɪs/                                                                                                   an artificial body part, such as a limb, a heart, or a breast implant. From Ancient Greek prosthesis “addition, application, attachment” or prosthetic implant is an artificial device that replaces a missing body part. Students will be invited to diagnose or analyze their patient / building through a series of fragmental design explorations generating key moments deemed worthy of preservation. This strategy encourages flexible thinking and the possibility of addressing multiple dimensions of a building. Design as such is not seen as a linear process leading to the creation of a final object, but as the guidance of multiple, simultaneously acting forces into an integrated assembly. The students will be tasked to design a house for a keeper with a small public program as an apparatus that will complete the existing and operate as a prosthetic implant.
