This project is the first in the series of four offered in the SURE-track and focusses on the building and street level and the theme of Sustainability. Due to the growth of the population, an enormous demand for dwellings and other real estate, and the negative influence of vacant buildings on the quality of life, the discussion about the transformation potential of existing real estate has been resurrected. This offers real challenges for urban planners, designers, developers, and managers. In this project, various strategies are developed and evaluated to transform an existing building complex into a complex that meets market-driven needs and current and future demands, including sustainability, financial feasibility and risk analysis as well as other trends and developments.
