I know I have to suck this up. But the (attached) neighbours have been building their extension now for a year. They started up using builders who regularly blocked our cars in the driveway. Now they're doing it themselves which means noise from 8am all weekends. My dh only gets home from work at midnight, including saturdays, so likes (needs) a lie in on a sunday. Then to cap it all off, they have complained that our Alexa unit is too loud. There. Moan over.
As we're about to discover too, if they've got planning permission or it falls within permitted development rights, you have to suck up the fact that the extension is being built. But you don't need to suck up unlimited noise at the weekend. Check your local authority's guidelines on working hours and ring their enforcement team if they're making noise outside those hours. If DUT builders can't comply with those hours, that's their problem, not yours.
Not being unreasonable in terms of the times they are doing it, our neighbours moved in and completely gutted/redid the whole house. Fine in the week as we both work full time and it wasn't a problem them starting at 8am as normally about to leave by then. But then they stepped it up (trying to move in before xmas) and one Sunday morning, 8am, I was fast asleep and they started drilling on the other side of the bedroom wall. I lost my shit! Threw stuff at the wall and shouted loudly and they immediately stopped until lunchtime 😁 I would have a word and ask that they try and limit the work to reasonable times, it isn't fair to have to listen to the noise 7 days a week.
