For the last ten years, new training programs centred on real estate management and finance have seen their development soar around European countries, at graduate, postgraduate or executive levels. However and paradoxically, real estate business case studies are not yet such developed in European countries. Thus management and real estate case studies examples for training and education are still very few and concern more US or Asian experiences than European ones (see for example the ECCH case studies catalogue). The aim of this contribution is to expose a successful example of contribution between real estate industry and academics for developing a real estate case study in the European property market context. T1 Tower is thus one of the first multimedia case studies (developed in collaboration with SITQ) which places students in the position of a property developer who must analyse the Paris commercial property market in order to decide whether or not this is the best time to develop a property in La Defense Business District.
