The site presents an attractive diversity of topography, landscape and habitat. At the centre of the land in question is Colney Hall, once owned by the Barclay family, and regarded by the residents of Colney as the former heart of their Parish, providing in effect a Park, with varying degrees of access for the local residents.
The Colney Hall estate occupies approximately 29 hectares (excluding the Woodland Burial Ground) in the north western part of the Norwich Research Park. It is accessed by its own driveway from the Watton Road. It is bounded to the West partly by the River Yare and partly by adjoining parkland, to the North by the River Yare, to the East by the River Yare and adjoining farmland and to the South by the Watton Road. Colney Hall is divided into two landscape character areas:More open parkland areas in the southern part of the siteMore wooded parkland to the north. In the northern tip of the estate, there is a County Wildlife Site known as The Heronry.
There are open views to the Hall from the South across the historic parkland which rises gradually from the Watton Road towards the Hall. The land slopes away quite sharply down to the north from the Hall and the Walled Garden eastwards toward The Plantation. The Plantation itself is fairly flat land with trees and glades, which slope steeply on the west boundary down to the river valley. Around the North, East, and West boundaries trees and woodland provide good screening from distant views.
The Hall itself is a Grade II listed building set within the remnant of a historic landscape. The landscape is not on the English Heritage Register of Parks and Gardens but is on the Norfolk County Council local list.
