I have just added this to the map of places to fly your drone at Drone Scene - Location # 600
Land owner permission not required.
One of the few places you can fly drones in London: https://www.royalparks.org.uk/parks/richmond-park/visitor-information/flying-drones-in-richmond-park
Parking is available and it’s a short walk to the flying field.
The originator declared that this location was not in a flight restriction zone at the time of being flown. It remains the responsibility of any pilot to check for any changes before flying the same location.
