It's an overgrown school field behind - the agent said the school only mow it once a year and never use it. The garden is astroturf
I am trying to move very close to my elderly parents - this is a 5 min walk from them and so I know the area quite well.

On Zoopla it describes this price as the owner's estimate
Agent was pretty uninterested so I didn't get anything useful out of her
