Thanks for the offer but that doesn't work for me, I don't want it bodged as thats easily possible with other pieces. The hole missing there is not flat and any angled pieces leave a gap visible above and below, it hurts my ocd too much which is why I just made it 1 square wider without ridges and I'll look into decorating the top at some other point, it just seemed strange that you can't build a right angle roof with roof ridges lol
