On the M25, take Junction 22. Follow signs for Radlett until you reach the first black and white mini chevron roundabout. At this roundabout, turn right into Shenley Lane and follow for about 1 mile. At the next roundabout (Napsbury Park) go straight over and we are the last building on the right, next to the park

On the A414, take the slip road opposite Aylett Nursery (Shenley B5378) and turn left towards London Colney. After the playing fields, we are the first building on the left. The local area is shown on the map below. The red ring shows our location.
