New Extension Wooden Frame And Roof Panels Overlap Our Side ...

[boomster]

our neighbour bought his house from the Council and our's is still Council owned and the two properties are joined. No problem with that. However, our neighbour has got a builder to erect a lean-to on her back-door patio and the supporting frame side struts and plastic roof panels encroach a good 3" over our side of a dividing garden wall. Apart from looking an eyesore, rainwater will run onto our side of the wall and cause damp problems with the wall. (We have only just removed internal mould and decorated inside and can't afford to repeatedly decorate.)
We did make it quite clear to the builder as soon as we realised what he was about to do, so he can't pretend he wasn't aware of the problem.
I feel like cutting off the offending protrusion. Am I within my legal rights to do so? If, perhaps, you've had a similar experience, or know of someone who, I'd be most grateful for any helpful and useful advice regarding the said matter.

You are within your rights, but best to discuss situation with neighbour then just take your proposed action. As a council house, council ought to be interested in the land encroachment.

Thanks Buider'sMate. We have a meeting with a council representative at the properties in 2 weeks from now and I'll write to let you know how we get on.
