It’s a bit strange to create such a large gap on a street.

So, just an address node but no building here?

AFAIK, there is a new building, but it isn’t on UrbIS yet.  (Last time I asked friends at Brussels City, they were approx. 1.5 year late compared to the real situation, i.e. most buildings where construction started less than one year and a half have not been sent to UrbIS.)
