Björn Hennemann (Leun) is the first graduate of the architecture programme at the University of Applied Sciences Giessen -Friedberg. Department of Building he successfully passed the diploma examination in the young course, which began teaching at the University of Applied Sciences in 2001.

The standard period of study for architecture at the Giessen -Friedberg University of Applied Sciences is eight semesters. Björn Hennemann was able to obtain his diploma after only three years because credits from his previous studies in civil engineering were transferred. There are close links between the two Degree Courses offered by the Department of Civil Engineering, allowing study periods in the other discipline to be recognized as qualifications.

Students of architecture at the University of Applied Sciences in Giessen can choose between two specializations: building renovation and construction management, and project control. Björn Hennemann opted for construction management. In his diploma thesis, supervised by Professors Nikolaus Zieske and Herbert von Wehrden, he focused on two main tasks. He created an architectural design for the vacant "Old Post Office" on Bahnhofstrasse in Giessen . He also presented a concept for the construction process, including cost estimation, scheduling, and the preparation of specifications.  

With the development of a design for the listed former post office building, he dedicated himself to a project of building within an existing structure, a field of work that is gaining in importance. For the existing floor plan and the rear building, the task was to propose a suitable use and to concretize its practical implementation through an architectural design. Any necessary extensions had to be integrated into the urban planning and design context.

The young architect envisioned the entire complex as a hotel and conference center. The plan calls for a restaurant and bar on the ground floor, and administrative offices on the upper floor. For the rear building, which would be enlarged by adding another story to the roof, Björn Hennemann proposed hotel rooms, seminar rooms, exhibition spaces, and a wellness area. He also designed expansion space and direct access for the neighboring "Mathematikum" (Mathematics Museum).
