I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission requirements unknown.
The marker is at a layby where you can park (switch to satellite view to see it)
Walk north about 500 meters on the grass verge (talk good walking boots) and you'll see the estate from a high evaluated view near the roadside giving excellent views of the estate and should have no issues with VLOS from outside the estate boundary.
Be wary of road traffic when taking off and allow plenty of battery before landing to ensure landing is not rushed to again take into consideration of any traffic. A high vis may be advantageous if you want to make yourself highly visible as it is a 50mph road.
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 16/10/2022. It remains the responsibility of any pilot to check for any changes before flying at the same location.
