Description
The two-storey building in the southern part of the Fire and Rescue Station 2 in Hannover-Stöcken is the largest construction project of the Hanover Fire Department since more than 30 years. On the ground floor a pioneering institution is located, in order to be even better prepared for major loss events: A disinfection device for emergency service personnel and vehicles, a medical storage and a vehicle depot. The paramedic school upstairs meets the criteria of passive house construction.
