One of the more controversial issues in building conservation is facadism: the situation where a historic facade is preserved, but an entirely new structure is constructed behind. Is this meaningful preservation, or the reduction of history to a thin shell of decoration? The relationship between public front and private interior is gone; the three-dimensional is flattened. Where the new building is larger and taller - as is often the case - then scale and context are also lost. At the same time, beloved streetscapes are being saved even if they are somewhat illusory. There can be few more blatant, or incongruous, examples than this: the facade of its 1928 predecessor stands like a tiny film set in front of the post-modern bulk of the Lloyds Building.
