There's no long saga of battles with the builder or anything. We have been up till the last week pretty much perfect customers from a developers point of view (coughed up the money at start of year and sat back and waited to be called). The actual problem is that one of the doors leading onto the hall does not have an architrave while the other 3 do. The reason is that the wall is too thick for it to have been fitted as per the others, we said fine why not do a "fake" architrave to restore the balance to the whole hallway and give the impression of 4 identical doors....they have said no and are continuing to say no.
we were intending to hold off on closing but outside factors are meaning that this is increasingly an unlikely option for us.
Overall yes it is a rather minor thing and one I was initially fairly easy going about, their absolute refusal to do anything is now getting my back up though!
