What should be considered before proposing new development?

• Be aware that the proposal could affect historic structures or areas, some of which are protected by designation, n.b. there are limitations on the scope for demolition and alterations without consent, especially to listed buildings and in Conservation Areas.
• Where building activity is involved or land/property is designated or listed etc, seek early expert advice from District, City or County Councils and preferably employ suitable professionals to bring forward your proposals.
• Retain and re-use existing buildings wherever possible. This is a fundamental sustainable approach and should be considered at the outset. Where demolition is necessary, assess the nature and significance of the asset in its setting first.
• Ensure that any new buildings are sensitive to their locality. The key to success is thoughtful design, enhancing the historic base wherever possible.

What should be considered if a proposal might affect archaeological sites or historic landscapes?

• Consult with the City or County Council’s archaeologists to determine if these sites/landscapes are likely to be affected and whether a desk-based assessment or a field evaluation (excavation) needs to be undertaken.
• Recognise that archaeological remains are fixed components of the site, to be treated as seriously as ground conditions or drainage.
• Be aware that design solutions can lessen the impact of development upon buried remains, perhaps avoiding the need for expensive excavations, but success often depends on early identification in the planning process.

What should be considered when converting or re-using an historic building?

• Consider the effect of development on the architectural and historic interest of an area/building and seek design solutions that are compatible with the character. The preservation and restoration of key features can enhance the attractiveness and value of a development.
• Seek out uses which maximise the qualities of a historic building. In town centres, for example, the re-use of upper floors above commercial premises can help to ensure the long-term survival of the building.
• Favour traditional materials and application methods to avoid permanent damage to the character and fabric of a building, for example, lime based plaster, render and paints.

What should be considered when refurbishing or extending an historic building or structure?

• Reduce energy loss where it can be achieved without harm to the character and importance of the historic building. Often, set-solution or new energy standards applied to new buildings may not be suitable for historic structures and more imaginative methods of upgrading are required. Some flexibility in the application of Building Regulations is allowed, and most historic buildings can be viewed as special cases in regard to Part L.
• Ensure that new insulation is accompanied by appropriate means of ventilation to avoid damage to roof structures caused by condensation.
• Traditional timber windows can be sensitively up-graded by adding separate secondary glazing or insulated blinds or shutters. Avoid their replacement with PVCu and other unsustainable products.
• Recognise the likely adverse impact of solar and photovoltaic panels on visible roof slopes (or free standing).
• Extensions should aim to meet the same high standards of sustainable design as all new buildings.
