Build Rooms in the Visual Designer

You can physically build multiple rooms in the designer using various assets like walls, columns, doorways, etc. However, they will all appear in the list view as one large order, sorted in order of how the products are added to the design view. You cannot designate certain rooms to certain folders at this time. 

The other option for building multiple rooms is to create a unique design for each room, which would then appear as unique orders/invoices for each room.
