I remarked on a cluster of white things in and around Lock Road a few years ago (2009 to be precise) and now they have been joined by a lot more white on the other side of the road. The street sign rather gives it away that this is the junction of Lock Road and Back Lane.
The extension has taken a lot of the garden and the wall continues to block what was the front of the house which used to be open to the street. The whole effect is to make the house untypically private for the area and slightly intimidating. Thanks to the lack of windows it looks more like a prison that a home.
