I am looking to floor a floorboarded through living and dining room, including hallway, and am veering towards engineered wood as it seems to be the way to go for quality but avoiding solid wood expansion/buckling problems. It seems pretty straightforward with a plywood base and then the sections glued on top if my research is correct. I also understand I would need an expansion gap between the two rooms, and at the hallway door presumably as it is parallel with the division of the two rooms and therefore also is effectively the middle of a double length room. Is there any more subtle way of leaving a gap between rooms and at the doorway than the standard wood/plastic/metal strips which are rather bulky and unsightly ? They are OK at the doorway at the end of a room but in the middle of the floor seem to me rather clumsy looking. Our old house also had a through lounge and we had it laminate floored by a friend who didn't leave any gap in the middle with no obvious problems for around five years.
