BOSS (Building Organisation Student Society) was founded by students in 1993 as the student association for the department of Management in the Built Environment (formerly known as Real Estate and Housing), at Delft University of Technology. The association is a connection between students and education. In addition it serves to facilitate contact with students and practice. Various national and international activities are organised by BOSS to achieve this.

BOSS has over 200 members and offers them the possibility to get acquainted with the sector and to develop themselves alongside their studies. A large part of these members is active in committees in order to make the activities truly unique events. The enthusiasm and dedication shown by the members in this is clearly expressed during the successful activities that BOSS organises.
