The second drama is a simple one but not easily fixed.
I am having a built in robe in one of the bedrooms and unfortunately the plans were read incorrectly. The robe is 100mm too short which means a coat hangar will not fit into the robe .... not a great outcome so they have to redo it. Sounds simple right but the problem is that the roof, cornice and all the built in stuff needs to be removed.
They are fixing it not a problem but still ... poor builder!
