Ladder it and jump over,i do one similar to that every 6 weeks.Wait for the comments on H&S but it works for me,there`s far to many to go indoors of every one and it would be a logistical nightmare for the live in caretaker to makesure they know i`m coming,there the same as them low 3rd floor balconys surrounded by grass and the ladder wedges right in against the wall so to be honest it`s safe.
