Hello AshviniNihara. Please note these recommendations for future edits: https://wiki.openstreetmap.org/wiki/Good_changeset_comments. A single word is not enough information for other users to know what changes you have made.

Also, the name tag should only contain the name of the item, not its description, so name=building is incorrect.
