It makes predictably depressing reading. In short, the listing is being left as it is but with a few modifications being made to its file.
As I understand it, EH essentially states that ACD's fame as an author is pretty much the only reason that house is even Grade II listed. The house itself is not considered to be in possession of any features that would warrant an increase in protection. The report also states that unless some significant new information comes to light EH won't consider conducting any further reviews.
To say I am not impressed is an understatement. It seems that in English Heritage we have an organisation that is content to watch this part of it vanish.
