Hi,
Thank you very much for having a look on it.

Yes, I accidentally added it twice, as a node and the building. Didn't meant to do that but it was late when I noticed it. Node is fits better than building because like you mentioned, its apartment building. Our legal registration address is here but we also partly operate here. On the ground floor we have areas which is used as small warehouse. Also customers use this address for picking up their goods/orders. 
Development itself is going on different address but we do not have public access to it.
So its one of our locations which is legal address but also we actually(not fully) operate here.

I would love to provide more information whenever its needed.
