We’ve received a letter from the council about an application for planning permission to build some flats next door to our house. But they’ve already started building work, and attached the front facing wall directly to our property. I’m not sure they have the legal right to do this.
See a solicitor immediately. At the very least you should have received two month’s notice under the Party Wall etc Act. If they don’t have the right to build on to your property it will be better to stop the work going ahead at an early stage than to try to get the builders to rectify matters later. You may need to take out an injunction to prevent damage to your property. The planning permission issue is separate, but you should discuss what’s going on with the planning officers.
