Hi, welcome to osm.
There are a few problems with the terrace you had added.
The building outlines on the property are expected to be traced instead of the shape of the land plot or building lot on which they sit.
The addr:housenumber has an ‘ accent added after the number.
The street name needs to have the ‘street’ part with an upper case S.
As the osm is essentially a database from which data is extracted to enable maps to be made or for navigation or other data evaluation, it is important that the correct and exact formatted data is entered into osm.
