Multiple Rooms Are in the Same Enclosed Region

This warning displays when multiple rooms reside in the same region of the building model.

Warning: Multiple rooms are in the same enclosed region. The correct area and perimeter will be assigned to one room, and the others will display “Redundant Room.”

Issue: In schedules, Revit displays Redundant Room.

One of the rooms displays the correct area and perimeter. The others display Redundant Room so that the space is not counted more than once in schedule totals. When a view displays the rooms using the Interior Fill visibility setting, the rooms that report Redundant Room display in a darker color because the room areas overlap.

Solution: You should separate the regions, delete the extra rooms, or move them into different regions. Do either of the following:

• Use room-bounding model elements or room separation lines to divide the region into multiple rooms.
• Remove the extra rooms.
