Exit the M5 at Junction 4 and take the A38 signposted for Birmingham.
This road is called the Bristol Road - just make sure you are heading for Birmingham!
The A38 is a dual carriageway all the way to Longbridge.
As you come to Longbridge, turn right at the top of the hill onto the B4120.
Low hill Lane is just under half a mile on the left hand side.
Enter by Gate Q from Low Hill Lane.
