One of the rooms is quite large at 18' x 16' and another smaller room has no door and leads into the hallway.
1) Is it OK to lay the larger room in one piece with a standard 10mm gap around the perimeter or will it need to be laid with an expansion gap running along the middle of the room. Obviously this gap would have to be covered with a joining strip.
2) Does she need to leave a gap between the smaller room and the hallway and fit a joining strip or can she just continue into the hallway?
I hope these two questions make sense.
