The evergreen shrub at the far end of the picture is a Choisya,, and as Flowers says the nearest one is a hydrangea. Both are shallow rooted shrubs and will do no damage to buildings.
No need to worry about those.
There's something a bit taller to the right of the caravan - I can't see it clearly enough to identify it.
