Rehabilitation design is not an activity restrictedly practiced in Architectural offices, but also taught and practiced at Architecture schools. Architects and students have to define their own method to approach rehabilitation design developments; however, they can be theoretically supported. The doctoral research RE-ARCHITECTURE theorized a rehabilitation design process; which was tested by Architecture students in the Netherlands and Portugal, during the academic year of 2005/2006. To better control the effective degree of the contribution, students filled in two questionnaires, one before and one after the development of a rehabilitation design, sustained by RE-ARCHITECTURE. These results sustained the improvements and developments of the simultaneously developed design process support system, REARCHITECTURE®. This paper presents a survey of the results of the Portuguese students.
