Not sure if the residents of this property: https://goo.gl/maps/8t77GFvbCKSKAtxJ9 have taken any precautions. It's grown very big.

Wow. I know it can get pretty tall but its rare to see it that tall in this country.
I'm guessing its grown through the pavement as they've got a different section of tarmac out the front. Compared to the lovely paving stones outside the other houses.
It does look glorious though.
My old house in Chiswick had it planted out the back instead of hedges. My mate (who I was renting from) told me he'd planted it with a barrier (to stop it spreading). But it'd grown over that into next door's garden. Fortunately next door was in her senior years and the garden was left to go wild so it wasn't too noticeable. Its going to be a bitch to get out.

You could build a couple of bike frames from all that.

Not you, but the previous resident may have. If its been there a while it may be ok. It spreads like crazy. Usually people will put a solid or material barrier around the bamboo to stop it from spreading.

Its not a huge plant so personally I'd stick it in a decent sized pot (making sure to get it all when you dig it up). You have to water it which is a ball-ache but its pretty bad if it spreads. It can grow through concrete. Probably unlikely with that small plant and your chunky slab. There was a house up the road from me when I lived near Chiswick where the bamboo (a fairly big plant in fairness) had grown under a brick wall and through the pavement.
