The development will be located off Silfield Road, north of the A11 and south of land which will be developed by Endurance Estates. Outline planning permission for 500 homes on the site was granted by South Norfolk District Council in February 2014. The land covers an area of approximately 21 hectares (52 acres).
Phase 2 will be directly accessed of Silfield Road to the west, approximately 100m north of the A11. Any potential impact of the development proposals on the local area has been carefully considered throughout the design process and through discussions with South Norfolk District Council.
The masterplan accommodates sufficient parking for residents of the site, and complies with South Norfolk District Council’s car parking standards for new residential developments. A majority of the houses will have private driveways with garages, to help ensure that all parking for new residents is contained within the development.
The site is in a sustainable location with good connections to bus and rail services, providing accessibility to local facilities and services. The nearest existing bus stop is located between the junctions with Park Close and Green Lane and is therefore within easy walking distance for the new residents, while Wymondham rail station is located approximately 1km north of the proposed site access.

As part of the initial work carried out gathering information for the site, a Site Specific Flood Risk Assessment was prepared in support of the outline planning application.
The site is identified in Flood Zone 1, which comprises land assessed as having a less than 1 in 1,000 annual probability (<0.1%) of river or sea flooding in any year.
The majority of the site drains via ‘greenfield runoff’ with the eastern section of the site draining north east towards the River Tiffey, and the western section of the site draining west to the Bays River. A small portion of the eastern section of the site is drained via an existing ground drainage system which outfalls into an open drain.
Any increased runoff associated with the proposed development will be attenuated down the existing ‘greenfield runoff’ rates, using sustainable drainage methods such as attenuation ponds and vortex flow control devices.
An Environmental Noise Assessment was prepared in support of the outline planning application to establish the noise conditions across the site off Silfield Road.
The assessment found that the main source of noise affecting the site was road traffic along the A11. To ensure that internal noise levels meet the agreed criteria in the new homes, we are proposing to install acoustic glazing and ventilation.
Furthermore, a 2.0m high close-boarded timber fence is proposed along the length of the A11 boundary.
Overall, the site is of low ecological value, lacking flower-rich verges or substantial areas of semi-natural habitat, although two lengths of hedgerow qualify as ‘Important Hedgerows’ due to their richness and overall character.
No bat roosts have been identified on site, and the on-site ponds do not have great crested newts but there is a nearby garden pond with great crested newts and the adjacent verges on the site may be used to some extent.
Our proposals include high-quality ‘green infrastructure’, intended to provide on-site habitat for wildlife – including great crested newts and birds – while also serving to provide corridors of habitat to maintain and enhance the movement of wildlife across the landscape. These habitat corridors are intended to connect the adjacent development and to maintain links between the Lizard conservation area and other areas to the north with the open farmland to the south.
A number of existing trees have also been incorporated into our design while boundary vegetation around the site will be enhanced with native shrub and tree planting.
