Thats good advice. When getting PP for our stables, we emphasised it being back from the line of the house so that the views were maintained, and also specified we would paint them dark green to make them blend in. It works too, when viewed from the signed walk on a hill in the distance, you cant really see the stables but you can see the soft pink lime harled house very clearly.
If theres no fencing near the house, it almost gives you an opportunity to define the curtilage where restrictions will apply - ie we did this, we put the fence x yards back from the back of the house and now as far as planners are concerned, thats the curtilage from what I can tell. NB they do also still have with listed buildings the ability to control stuff which is outside the curtilage affecting the buildings context but as long as you are sensitive with where you put things or (if PP/LBconsent needed) you show you are trying to minimise impact they are (from my experience) not too bad. The main thing they are concerned with is the house, if you play ball with them on materials (2x the cost of normal) and techniques (2x) and dont try and apply for unsympathetic extensions etc they will prob be happy. eg ours is B listed (GII* equivalent) but although they wouldnt allow any alteration to the footprint, we did agree with them that on the plain rear of the house we could have a small sloping mansard roof for part of the width which meant we could fit in two ensuite showerrooms to the bedrooms. Yet on paper this would be a no-no, but they recognised that actually it improved the look of the rear.
just some thoughts, hope they help.
