Hello, and welcome to OSM.

A bit of warning here.  Please never redraw buildings on OSM by following aerial imagery.

Buildings are traced by following the official outlines.  You can find a preview as "Digital Vlaanderen GRB" in the list of backgrounds.

Aerial imagery is distorted and does not show reality.

Also, we do not repeat postcode and gemeentenaam on every address in OSM, this is not necessary because we already have full coverage of postcode and city areas.  This calculation is automatic.

We had to undo your edit.
