The extent to which an asset contributes to the architectural or historic interest of any group of assets of which it forms part, particularly where assets comprise an important architectural or historic unity or a fine example of planning, where they make a significant contribution to the streetscape or area or where there is a historic functional relationship between the assets. Sometimes group value will be achieved through a co-location of diverse assets of different types and dates; groups of assets that together fulfil one of the other criteria.
Group value recognises the importance of setting for heritage assets, both individually and collectively.
Group value can add significance to assets worthy of designation individually, or can be applicable to groups of assets that do not merit individual designation.
Where assets which individually meet other criteria have a clear visual, design or historic association with one another the whole group will be considered for inclusion.
Within the Cambridgeshire Local Lists, group value may also recognise the contribution of an asset to the setting of an asset included on the National List, or could be applied to former ancillary buildings that do not meet the definition of being curtilage listed.
Examples may include a group of prehistoric ring ditches forming a cemetery, a collection of estate buildings designed by the same architect, or a historic farmstead which retains the farmhouse and associated buildings including barns, cartshed and stables.
