quick draw macgraw

Thanks do you still need expansion joint as they are both concrete and does the edge of tiles have to start at this joint what if you get crap cuts at both ends of room? Suppose i'll know more when i look at it.
Stumac i was going to square them with the entrance door with longest run in but there are no units in yet and as the walls may be out the tiles may run out away from the kick boards looking crap.

Cheers Steve.
