Yes, Digitaal Vlandeeren GRB is the layer you can use to draw buildings.
I was planning to do a revert but it proved impossible because you have been changing more stuff in this area since this change.  I will try to do it manually.

I am actually quite horrified at the number of mistakes.  I admit that it must not be easy to get your first contributions right.  With respect, I’d like to invite you to consider doing fewer changes on the same day and spending a little more time studying how the map works and how we tag objects.

I was preparing an email to you to warn you about several mistakes with today’s edits, namely this: Silly shapes like this, which I found in invalid multipolygons, https://www.openstreetmap.org/way/1192331501
Areas overlapping footways, double or triple definition of some addresses, abuse of the layer tag (probably to escape genuine warnings by the iD editor), damage to building outlines, and more.

I will try to spend some time fixing as much as I can.  I will ask other mappers to help.
