Considering the youth population in Eskişehir, this project aimed to gather undergraduate students from all universities to learn and examine the field of “sustainable science”. To demonstrate the purpose of the museum, the building communicates with the existing green areas and the surrounding environment; also, because of the location of the site, diverse accessible paths and having a courtyard in the center make a welcoming approach for visitors. The most important feature of the project; the tree exhibit, starts from ground level to the upper parts that provide sun-light to all floor levels.
