Laverstone Gardens does not exist. There is no postcode for it, it is unlisted in the Hertfordshire A-Z and Google thinks it a derelict factory building approached via Offly Street.
The seven residents of this cul-de-sac are more than happy with this state of affairs. The postman knows where they live, as does the electricity board, the gas company and BroadWater. However, since their houses don't appear on the map, they are never bothered by cold callers, religious groups or campaigning politicians. Their council tax is based upon the theory they live on undeveloped urban waste ground and is therefore lower than tax band A but they do receive annual grants toward their food and shelter.
Laverstone Gardens appears in this guide book by permission of the residents, but they denied consent to include it on the map.
