What if a tree within a conservation area is removed without permission? If we are notified we will have to investigate why the tree was removed, and if its removal was not justified we may prosecute the person who removed it. What if I want to do work to a property in a conservation area? Any changes you make to a property through repairs, maintenance or alterations, should be in keeping with the character of both the building and the area. You should take care to match original materials and methods of construction, and avoid damaging or removing features of historic or architectural value. Planning permission may be required for these works including any demolition.
