Charlie Dimmock and Tommy Walsh create a garden for a lock-keeper in Molesey, Surrey, on the bank of the River Thames. While the oblivious owner is away on a health and safety course, the team builds a shady, secluded area with decking and a small water feature, as well as using a new process to lay cobbled paving in record time. However, while the rush to meet the usual two-day deadline, lock-keeper Steve is not in any hurry to come back.
