Thanks to Jacqui Wall who identified this as being the Assistant Manager's House (and not the Manager's House as previously identified!) and told us this about the history of the house, "although initially lived in by Arthur and Bet Williams (and their 3 girls) for a short while whilst awaiting completion of their 'proper' house, it actually was used long-term as the assistant-manager's house. The true manager's house was a 2-storey one situated just inside the entrance to the camp on the left."
