“There are numerous cracks in ashlar stones on the external elevation. Mr Green suggests pointing these cracks with a putty lime mortar, pigmented to match the stones. Mr Wilshaw promotes the idea of replacement of the damaged stones with reclaimed ashlars. Mr Wilshaw rejects the visual and structural adequacy of a pointed repair. I agree with him. As with so many matters, neither repair (pointing with pigmented putty or replacement with a new or reclaimed block) will replicate the building's condition immediately before the subsidence occurred. However, bearing in mind the intent of Parliament as set out in Section 19 of the Act, I have no hesitation in deciding this matter in favour of the replacement block proposal. No matter how skilfully any pointing is done, I believe that putty lines over the surface of the damaged block will look visually intrusive – both immediately upon repair and subsequent to a number of years of weathering. I should just add that in giving consideration to these matters, I recognise, as Parliament did, that these buildings are to endure for many centuries to come. The repairs undertaken now need to stand the test of time.”
