Welcome to OpenStreetMap.

I can see from your website that you operate from 84 Strathville Road, but what your edit has inadvertently done is to remove the building from the map.

If your company premises occupy the whole building, then you might want to add something like office=company and/or an appropriate value of craft=*, together with tags for contact details and website. This lets data consumers know what sort of map feature you are, as they won't see your website address in the changeset comment.

If the business occupies only part of the building, it might be better to map it as a separate node (point).

I've added links to the documentation for the tags below, but if you'd like any help please reply below.
