Robson Green explores the extraordinary lives and homes of the people who live on Britain's coastline - from families who are swapping their city homes for a new life by the sea to those who have lived on the coast for generations. Robson's coastal journey reaches the east coast as he finds out more about the community spirit that makes life by the sea so fulfilling. This week he meets a couple living on a seal sanctuary, the volunteer lighthouse keeper who lives four days a month at the remote coastal location of Spurn Point, and meets the people who live on the former World War I campsite that today houses chalets with listed status.
