A couple of weeks ago a mature tree was chopped down in southbank rd (the one leading down the hill to the back of surbiton station). It stood outside Beauclere House - actually a block of flats. It was on your right about half way down the hill - at one end of a street flowerbed.
The council say it was a sycamore but from my recollection it was an oak.

Can anyone help on the id?
