I might be wrong but building new houses in Avebury will probably not regenerate the village. With the school now gone and the post office/general store about to close as well any real village infrastructure (other than the social club, playing field and church perhaps) no longer exists. Inevitably, people who can afford it will move into the new development on the Bonds Garage site and, although that is not necessarily a bad thing, I fear it might be the thin end of the wedge with not just five houses being built on the former garage site but many more at the back as well (and later [and even worse] wherever developers can get their hands on land in the area).
The only really safe option is a green zone around Avebury where no further building (with the possible exception of small improvements and extensions) is allowed.
