Welcome to OpenStreetMap and thanks for adding these.

If you want to map a new (presumably residential) building as a point because the aerial imagery hasn't caught up yet, you might want to use something like:
building=residential
addr:housename=Naymar Court
addr:postcode=NW10 7SR

This will help data consumers understand what you've added.

If you'd like any help, please feel free to ask.
