From the latest pic, it was planted on the slant. So what you are now seeing is the true height.
It has a very narrow space on their side. If it doesn't run, it will push.
We haven't seen a view of ground level your side. Do you have the space to sink a barrier? Do you have the space to dig/cut out any invasion, oerhaos annually?
... a clumping bamboo. ... It took me just five minutes to slice down through the roots
Once when I moved house I tried to take a division of a bamboo with me. It was the end of the day and I was getting tired. I spent over an hour with a sharp spade, pruners, pruning saw and axe, and made little progess. In the end I left it.

The height of that new growth and the existing green canes look very much like Phyllostachys bissetii, often sold as a hedging plant which is probably why the developer used it. I have some in my garden. It is a running bamboo and definitely more vigorous than any others I grow. Mine is planted in the confine of a walled border and on shallow soil so it has behaved itself, so far! It provides a very effective screen to hide my neighbour's home office.
If you remove any unwanted emerging canes and roots around now, when they are easy to cut, the clump can be controlled. The growing season is about six weeks, so by the end of June, there should be no further threat of new canes developing.
However, if you don't keep a close eye on it and manage it carefully every year, it can become problematic. I'd speak to your existing neighbour about it, and, if not remedied, your new neighbour. Ideally, it needs to be removed or a robust root barrier needs to be incorporated along the fence to prevent intrusion into your garden.
@Plantminded It was thanks to your help that I chose it. It is also known as Red Panda bamboo. You can just see it at the end of the border. You know that photos are not my thing!
I have worked as a Gardener for 24 years. My latest garden is a new build garden on heavy clay.
I'm starting to wonder if bamboo shouldn't be regarded as invasive now. Not a plant I'm overly keen on, although I did have a Fargesia variety many years ago in a previous garden. I haven't seen it escaping into the surrounding areas, so I can only assume it hasn't been troublesome I know I've posted before about an item [probably on G'sWorld] with a bamboo expert, and he said that they can all get out of hand if you aren't careful, regardless of type. I certainly think there should be some warning on the running kinds, and they definitely shouldn't be used by landscapers. A disaster waiting to happen...
It's a place where beautiful isn't enough of a word....
I live in west central Scotland - not where that photo is...
There is a trench between the fence and our soil, we had some clay soil dug out and replaced with fresh soil with wooden boards to hold the soil back from bottom of fence. So far no signs of bamboo and enough room I think to get a barrier of some kind in place.
Life's tragedy is that we get old too soon and wise too late.
That’s a lovely border @GardenerSuze, your bamboo makes a great feature.
A fair point @Fairygirl, a disaster waiting to happen for an inexperienced gardener who is unaware of the consequences of being misinformed. I wondered whether they grow well in your area and are less of a problem in your soil and climate?
That looks like you could incorporate a root barrier quite easily @Bright star. I have a row of concrete blocks below my fence to contain my bamboo but there are other textile type root barriers available which will take up less space. My soil is also shallow in that area with a solid sandstone seam not far beneath the surface so that helps too!
