The extent to which the exterior of the building contributes to the architectural or historic interest of any group of buildings of which it forms part, generally known as group value.
Department for Digital, Culture, Media and Sport
Group value occurs when a group of assets may not be exceptional, but together form a landscape that tells us about the historic economic, industrial or social development of an area.
This may include fine examples of urban planning such as squares, terraces and model villages. The assets do not need to be identical or of the same type, group value can be found in areas with mills and associated workers’ terraces, schools and churches for example.
- Are the assets historically linked to each other?
- Were the assets built at the same time, or as a planned group?
- Do the assets, when viewed together, form a group with similar architectural details or building materials?
