We were there last week, and as we had considered AYA previously, we took a quick drive by. The construction is directly behind it (further up the straight "road" from the etang), and construction still looked pretty heavy duty. There was a very large crane and at least 10 cars for the workers on the new villa. I have no guess on construction timing, but it was definitely still in the framing/foundation phase. Interestingly, it appeared there were folks renting it. The agency I spoke with refused to rent to me (see my post above), so either someone worked out a good deal or another agency didn't have the same standards. From what I saw, it is hard to believe that the work could be done in 5 months, but maybe the loud part would be...
AYA is a great looking villa with a central location, good view of St Jean, and relatively alone on the hillside, other than the work going on behind it. I don't think there was a villa on either side, but relatively older ones below.
