Listed buildings and protected trees in Winchester
Listed buildings everywhere in England are recorded by Historic England, and the checker looks for them at every address. Winchester doesn't publish listed building outlines, so where a listed building is recorded near an address, we ask the homeowner to check whether it's theirs.
Winchester doesn't publish its tree preservation orders as data. If there are mature trees near your project, ask the council whether any are protected before you start.
