“In considering whether to grant planning permission .… for development which affects a listed building or its setting, the local planning authority or, as the case may be, the Secretary of State shall have special regard to the desirability of preserving the building or its setting or any features of special architectural or historic interest which it possesses.”
“Historic Environment Good Practice Advice in Planning: 3” (2nd Edition - 2017). The document advises that an assessment be carried out which includes the following steps: “Step 1: Identifying which heritage assets and their settings are affected Step 2: Assess the degree to which these settings and views make a contribution to the significance of the heritage asset(s) or allow significance to be appreciated Step 3: Assess the effects of the proposed development, whether beneficial or harmful, on the significance or on the ability to appreciate it Step 4: Explore ways to maximise enhancement and avoid or minimise harm”
“Options for reducing the harm arising from development may include the repositioning of a development or its elements, changes to its design, the creation of effective long-term visual or acoustic screening, or management measures secured by planning conditions or legal agreements. For some developments affecting setting, the design of a development may not be capable of sufficient adjustment to avoid or significantly reduce the harm, for example where impacts are caused by fundamental issues such as the proximity, location, scale, prominence ornoisiness of a development. In other cases, good design may reduce or remove the harm, or provide enhancement. Here the design quality may be an important consideration in determining the balance of harm and benefit.”
