After a construction period of 13 months, the modern, two-storey extension for ADAC Pfalz was successfully completed above the existing garages. This created around 450 m² of additional usable space for employees alongside the existing administration building. The new building was designed and realised as a KfW Efficiency House 55. A connecting structure, also newly constructed, ensures short distances between the buildings. A photovoltaic system was also installed on the roof of the new building to ensure sustainable electricity generation.
