Here is one architect reporting affection for the Tricorn Centre.
Portsmouth, which has played such an important role in British history, can hardly boast such a rich galaxy of distinguished buildings that it can afford to see one destroyed. The Tricorn has been empty and neglected for years, but during that time considerable advances have been made in technologies for the cleaning and conservation of concrete. We have all noticed that public perception of what is beautiful or ugly works on the pendulum principle and reaches its nadir just before a fresh and positive evaluation.
