We bought our first house a few years ago and are set to self build our extension early next year. I have most of the build right in my head but wondered if anyone could puzzle out one point of the joint on a brickwork.
The thing that's puzzling me a little is that various wall constructions have been used previously and how they are going to join with the new. The original house is built of solid wall construction. The previous occupants built a second floor extension above the kitchen and the old drawings suggest this is built with a 250mm cavity wall on top of the solid wall with a cavity tray. The 2 story extension we're building is on the side of the house and the initial drawings are suggesting a newer 300mm cavity wall construction for this wall.
The perpendicular joint at the front of the house is easy enough with wall starters off the original brickwork. How am I best joining the 300mm wall up at the rear where the solid wall ground floor and 250mm cavity upstairs will be extended and old butts up with the new 300mm at is going to be out of whack in 2 places as the wall goes up?
Thanks in advance for any advice
