This book presents a huge number of contributions on corporate and public real estate management, urban development management, design and construction management and housing. These topics correspond with the names of the four sections of the Department of Management in the Built Environment at the Faculty of Architecture and the Built Environment, TU Delft, the Netherlands. The book is a Liber Amicorum for prof. Hans de Jonge to mark his farewell as professor of real estate management and development. Due to the special role Hans de Jonge has had for over 25 years in our department the book includes many other contributions as well, from his former and current PhD candidates, university managers, and academic and professional colleagues from inside and outside the faculty. It offers a diversity of words of praise, personal memories, solid pieces of academic work, and reflections on the present, past and future of real estate management and development. As such the book presents a very interesting story of twenty five years of teaching and conducting research being started, guided and/or influenced by Hans de Jonge. It shows the contribution that Hans, his team and others have made to the growing body of knowledge on how to match the demand and supply of real estate and how to contribute to an efficient and effective building stock that evokes interesting experiences.@en
