This looks like 2 buildings in the imagery **not** 1. If things look different compared to imagery please state this in your change-set comment to reduce the likelihood of other mappers changing the features you mapped. 

If it is in fact 2 buildings, then map it as 2 buildings and add a POI in the meantime (explain your intent/rationale in your comment for more complex situations). There are other ways to link features in OSM.
