Got home to find our neighbours have put scaffolding up all over their house. Some of the poles overfly our property, although none of the supporting 'legs' are encroaching. When we put scaffolding up to do roof works some time ago, we let them know we were doing so, as a courtesy. AIBU to think most normal neighbours living in a semi detatched would have let their 'other halves' know?!
(Also, I now have no idea what works they are doing, whether there is anything happening on our party wall etc. and no-one is home for me to ask...)
