Take the A1 motorway until it terminates and position yourself in the lane signposted for the city centre.
Follow this road, the B268, until you reach a roundabout (Ludwigskreisel). Here you get into the lane heading to Westspange/A620 and on to Völkingen and Luxembourg.
After about 5 km, you will come to the Klarenthal/Großrosseln exit. Drive off here. Follow the road to the next set of traffic lights and then turn left in the direction of Forbach.
Almost immediately, you take the next turning left in the direction of Klarenthal.
Follow this road. After passing the place name sign for Klarenthal - you should now be on the Kreisstrasse - drive straight ahead at the next traffic lights and, directly after the traffic island, take the first turning left.
Our office building has a striking high glass portal which you should be able to see from the junction.
