Every council in England works to its own local plan, and Bromley’s has to manage the largest land area of any London borough, more than half of it designated Green Belt or Metropolitan Open Land. Alongside extensive conservation areas covering village cores such as Chislehurst, Keston and Hayes, the council has taken the somewhat unusual step of removing permitted development rights specifically for upward extensions and roof alterations across sixteen parts of the borough, meaning adding a storey often needs full planning permission even where it wouldn’t elsewhere. BetterLivingSpace checks Green Belt, conservation area and Article 4 status for every Bromley property individually, so nothing we produce is generic and every proposal is built around what actually applies to that site.
