What about the question whether the wall (from which the extension is built) fronts a highway. If it doesn't then it doesn't matter whether it is the principal elevation. There may be a very large front garden containing lawns trees and shrubs. Or there may be a paddock or field between the house and highway. Can there be any guidelines as to the kind of distance which would be needed, or whether it would make any difference if the land between the house and the highway was non-domestic (eg a farm field). It does not refer to fronting the highway which serves the property, a factor which may be relevant eg in bypassed villages, as it could be a different highway the house has ended up fronting. Anyone have any thoughts?
