text: The building is already mapped as addr:housenumber=60 but that doesn't make sense as the building also faces Draycott Avenue and isn't likely to be number 60 on that side. So I've added a housenumber (52-54) to Knight Frank which is already mapped there.  But the entire building is tagged as KX sports and I suspect that is not the case. Probably KX should be retagged as a point node and moved to whichever part of the building has its entrance. Presumably too there are other occupants so a survey is needed.
