Repairs will be made to both the copper cladding and the stonework. The two domes will be completely covered to provide weather protection during the work.
The copper on the domes will be replaced like-for-like, retaining as much as possible of the original material; however, a significant proportion of the copper is expected to have to be replaced. As the work is on a like-for-like basis the City of Edinburgh Council has confirmed that it does not require listed building consent.
The new material will be unweathered copper so for the first few years the refurbishment will be very much in evidence. This will be an opportunity to take a full photographic record of the repairs once they are completed. The unweathered copper will take several years to acquire the familiar green verdigris.
