Option 1 is the author's house, which would be convenient but difficult for crew to access. Option 2 is Barnes Park, suitable for exterior filming but risky due to unpredictable weather. Option 3 is Sunderland College, ideal for a planned scene but very inaccessible for crew. After consideration, the author chooses their house as the primary location for convenience and ease of access, with Barnes Park as the backup due to better crew access.
