Must have dispensation , as a licenced runway needs 75m from runway centreline to a holding point. 49m is ridiculously close and the runway is narrower than a standard. A runway excursion could end up with an impact with that wall. When you look at it on Google Earth, I am surprised the CAA permit commercial movements. As for the spire in poor weather.......! If I applied to build a wall 49m from the runway at Luton, I know what the answer would be (ignoring who owns the land).
