The Community Assembly of Greater Norwich is located in an area covering Norwich City and the surrounding areas of Broadland and South Norfolk districts. It is a growth-focused region, incorporating urban fringes, market towns including Aylsham and Diss, and key sites such as the Norwich Research Park.

Greater Norwich has a rich concentration of historic assets. At its core is the City of Norwich, formerly England's second city, with its two cathedrals and many other historic buildings. It has the greatest number of medieval churches in northern Europe, monastic halls, former merchants' houses, the city wall and industrial heritage. Market towns, villages and hamlets show a pattern of development that has built up over the centuries, with a wealth of medieval churches, including a number of round tower churches, farmsteads and historic halls. A number of areas of formal parkland, such as those at Raveningham and Blickling Halls, are designated by Historic England.

Greater Norwich is surrounded by natural environments designated for both habitat and species protection. Many of these area are marshland, rivers or broads of international and national status classified as Special Areas of Conservation (SACs), Special Protection Areas (SPAs) and Ramsar sites for wetland importance.
