Radical ideas about reshaping the city lie behind the latest draft development plan for Dublin. Architecture never stands alone; there is always a context and, in the modern era, a planning framework laying down a set of rules about what can and can't be built. This used to be fairly primitive, based on broad-brush zoning - but not any more. The two-dimensional approach has been replaced sequentially by local area plans, integrated framework plans and now the development of tailor-made plans for "character areas" in collaboration with architects and other professionals.
