This is the entry point to LE2 3LR.  The little dotted line leads to 6 cottages not shown on the map.  These cottages are the only houses for LE2 3LR.  The cottages lie almost parallel to Knighton Church Road and at right angles to South Knighton Road.  This is a common error.  Google Maps has been corrected to show the entry point.  The current dropped pin for LE2 3LR is for a house on Knighton Church Road from which there is no entry to Egerton Houses.  Check Royal Mail find an address to confirm 'Egerton Houses' as belonging to this post code.
