Hi George,
In that case the Albert Dock should have been turned into a car park as proposed in the 1970s. There are many other buildings - warehouses, churches etc. which have been imaginatively restored. Look at the Novas building on Parliament Street as just one recent example. The external fabric of The Custom House was sound enough and the building should have been saved. There was a campaign to save it, led by Peter Fleetwood-Hesketh, but in the immediate post-War years, the politicians were chasing a different vision of the future.
