From Norwich take the A140 to Cromer and Aylsham. Stay on that road for approx. 10 miles until you reach the town of Aylsham. At the roundabout turn right and continue along the A140 towards Cromer.
Take the second turning left, about a mile along the road, to the Industrial estate. Take the first turning onto the industrial estate once you reach the long sweeping bend in the 30 mph speed limit and keep to the left.
