The Manager of Mitcham Common said in July 2017:

It’s my understanding that the remaining wall is unstable and will shortly be demolished and replaced by a wall and fence design very similar to the one that exists along the southern and eastern boundaries of The Meadows estate.

The new wall was photographed on 6th September, 2017:
