I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission requirements unknown.

The property is managed by the National Trust who control the land to the north and west and prohibit TOAL. The land to the south is not controlled by them.
It may make sense to park in the main car park (£4) and walk to non-NT land as the parking in town is very limited
