The buildings here share a section of a roof covering common walkway to flat specific entrances, however the buildings but do not share any common walls. In the national address database the two buildings have addresses Mankkaanmalmi 16 A and B.

Furthermore, each building is divided into 3 flats. I was not sure which way in this case the marking should be done do so for clarity I opted for marking the buildings as separate. If this is OK, just delete my note. If not, please advise of the correct way.
