@Ernesto77: The point here is that adding your house on the map is fine, and in that case it must be a regular polygon with the proper shape of the house and a "building" key on it so that it can be shown as a house.

Your edit was undone because you tagged it incorrectly, as if it was a mountain peak.  That is why other mappers reacted.

user_5359 was kind enough to draw the building properly.  You can try edit it now, and add more tags, as long as they are factual, e.g. the address.  Possibly more tags, such as the height, roof shape, color… that can be nice for 3D views.  Ordinary family houses do not have names.

Happy mapping!
