William Barnes on Architecture, Building and Beauty of Form

To make a blind window in a wall only to match a light-receiving one, or in the building of a stair-climbed turret to build a turret as its fellow only for the sake of a needless fellowship, or a matching of one with one, seems to be a slighting of the rule of fitness - no waste no want - and so of a rule of the Beautiful. A better rule might be -

     'Let your want give your plan,
      And then grace it as you can.'

From Thoughts on Beauty and Art, Macmillan's Magazine, June, 1861.

Does this rule or principle apply to Poundbury?
