Thank you for this, Nigel. I went back to the slide to check, as the new building looks so different, hardly recognisable. A whole new top floor has been added, and the wing on the lower ground towards the T-junction seems to be new, replacing a short square wing. The high, steep, rocky slope where the rescue was being carried out does not appear in the pictures, and I would not have thought Gansey Point high enough. The nearest such ground would seem to be west of Port St. Mary. Your local knowledge will be better than mine, Nigel.
