The most detailed map of Wonersh is on the Waverley Planning Department website. The map overlays house names and numbers onto an Ordnance Survey map which, being Crown copyright, can only be used under licence. We have therefore used OpenStreetMap which has the advantage of being free to use but is not quite as accurate as the Ordnance Survey, particularly with respect to the shape of properties. Additionally, we have had to manually add the house names to our maps and so we would be grateful to hear of any errors. Please bear in mind that we are unable to change the maps themselves, only the text we have added to them. We also have an interactive map here . Clicking on a sector map will bring up an enlarged version.
