I think this cottage is the one to the right of the bus shelter.
Lets get this right; come off the High Street by Frog Lane on the road that goes back to the A4. The cottage in question is on the corner, go straight on to the church. It's basically the same big wall before it now, and it's all one house.
The cottage you are on about is on the right going out of Lockeridge, going to Alton Barnes.
