Received the following information from my lawyer yesterday
"We are in contact with the developers and, for your peace in mind we can tell you that they have the Final Building Works Certificate approved by the Architects’ Association. They have already applied for the First Inhabitant Licence (this is the last licence granted by the Town Hall, which makes the properties habitable). Everything is progressing as planned and the developers are doing everything in their power for handing over the properties before the end of the year."
Looks like the end is in sight!
