cepezedinterior and cepezed together are creating the design for the modernization of the TN building at the TU Delft. The complex beside the Mekelpark, directly adjacent to the auditorium of the university, is one of the buildings at the faculty of Life Science and Technology (TNW) and dates from the early 1960s. The building is out-dated in several respects and no longer fits in well with the current requirements for high-quality research and education. Based on an extensive spatial-functional as well as technical concept Design Brief, cepezed devised an initial concept for the modernization. This focused entirely on compact reconfiguration, robust sustainability, the creation of a high-quality research and education environment and good integration with the surrounding campus.
