Also, buried in amongst the trees on Hanworth airpark is a pillbox or similar, it is located in the far South East corner of the Air Park, looking at Google earth it is on the crossroads of the Hounslow rd and Uxbridge rd (where the Horse and Groom and Hanworth library are located) does anyone know in which era this was erected?
The pill box is located nearer to Hanworth Park House in the middle of the Airpark, link below

The Pill Box is to the left of the red circle or select Birds Eye and face South. The pill box is now to the right of the red circle
I think the structure at the Horse and Groom crossroads you are talking about is an old Ice House, the area is named after it, The Mount.
It was built around 1865 by Algernon Perkins who resided at Hanworth Park House, and used it as an Ice House or Cold Store.

Again select BirdsEye and face South and you can just make it out in the trees to the right of the Red Circle.
