You see, the real problem here is that these huts were never intended to last long. They were simply built out of cheap materials and the priority was for them to go up fast. So they fulfilled their task admirably. However, the question now is how and to what extent do we preserve them? Always a tricky question.
Anyway, progress is definitely being made but it's not just a case of preserving what we have now but also ensuring that the site is maintained and accessible for the future.
