At this stage, the school is just this building: https://www.openstreetmap.org/way/177665619. That is what I tried to reuse for creating the school. 
As far as I know, two buildings are currently being renovated to be integrated into the school (https://www.openstreetmap.org/way/243138364 and https://www.openstreetmap.org/way/177665555) , but they are not ready, yet. So I imagine at this stage they should not be labeled as being part of the school ?
