Anything growing over, around or into an old building is bad news.
Ivy, Virginia Creeper and Wisteria are fine on a free standing well supported trellis but on a building the following problems are caused:
Trees should always be kept well away from a building, their roots often damaging primitive Victorian foundations.
If your station is in a Conservation Area you will need permission to remove a tree if the girth is greater than 150mm.
If the building is listed only a rare species of tree or shrub is likely to be in the listing.
Your friendly local Conservation / Historic Building Officer will be happy to advise, they are usually found in a District Council or Unitary Authority.
