The ethos and practical application of conservation has evolved from a concern with preserving isolated fragments of archaeological importance to enhancing the urban fabric through land use planning. Responding to successive threats and pressures for change has provided professional practice with a cumulative body of justificatory principles, which are often taken as the values supporting conservation planning. It is the exposition of these underlying tensions, which forms the basis for this book. Conservation and Planning examines the values underlying conservation policy and their translation into conservation planning practice. It is not an architectural study but examines conservation more in terms of planning, environmental, social and cultural policy. Two case studies of local planning authorities in England are used to examine how not only national policy is interpreted subject to local considerations but also how conservation values and concepts fare in their real-life application.
