I visited these buildings with Anna Dimitriou last year in Oktober. The buildings were already looted and there were some graffiti. Even if they are not in the zone of the old airport of Athens I guess they are part of it. There is a plan since 2013 for development in the area and just recently the government announced the demolishion of some buildings. But I wasnt sure which buildings they were so I went for a quick visit couple of days ago. There are still a lot of things and few walls are intact. Hopefully next year I will do some stuff there before its completely gone.
