Hi, thanks for mapping. 

The buildings you mapped are well done as to their location. 

However, you incorrectly tagged a few buildings with a layer=-1.

Layer is typically used when some things (like a bridge and a road) are on top of each other. The layer tag helps the map know which one is above or below the other in real life.

That is not the case here. Probably you were confused by the fact that your editor proposed to add a layer when buildings partly overlap each other.

Instead you should opt to reposition the buildings.

Thanks so much for your contribution, Martien, HOT global validator.
