Many of the proposals are greenfield sites. I am aware that a number of other sites have already been given planning permission but have not yet been developed. For example the Dane Lane/Bedford Road area of Wixams has a site that has been fenced off ready for work but nothing has happened for over 5 years. This site has some derelict housing on it. I am concerned that developers are looking for easy site options and not bothering with the more difficult / more expensive sites that require more detailed preparation. Another possibility is that developers are holding land hoping to change the planning to a more attractive proposition. If, as the Local Plan implies, there is a requirement for housing then it would seem important that sites already allocated should be developed before new fields are swallowed up.
