I spoke to the lady who lives at number 3 and she says there are 3 cottages there, 1, 2 and 3. Nothing has been knocked down or added to the cottages. The cottages are in a X shape. 1 and 3 the end ones. 2 and 4 were the ones running vertical which has now been made into 1 cottage (no 2) but is very small.
Thanks for your help anyway. much appreciated.
