Wall plates on curved inner leaf wall

[health mechanic]

The brickies have built up the inner leaf of thermal blocks slightly inwards to meet the inner leaf of the old bricks which were 115. This means the wall plate sits on the corner end of the new extension inner leaf on full thermal bricks but where it joins the old house sits only on 50% of thermal blocks, with other half hovering over cavity. My worry is that the weight of the roof joists may cause cantelevering into cavity. There are dwarf walls about 80cm in from the eaves. But not sure sufficient to

Did your brickies not have a string line?

[health mechanic]

Old external cavity walls were 105-70-100...total depth 270.....new are 100...100..100...total 300

 

 

 

Not issue on gable ends..where no wall plate, but front where front it is as half old wall , half new.....rear is stud so no issues 

 

Seemed they wanted to marry up with inner leaf

That’s some dog$hite blockwork ..! How’s the wall plate going to be held down as your straps will be a challenge if the wall plate isn’t flush to the inside wall. 
 

To fix this I would install a wider wall plate and let it overhang into the cavity but be flush to the inner face.

Why do they want to make the new wall plate inline with the old? They haven't done a lap joint so it's not like they are tying them together.

 

I agree with @PeterW, you can't put straps on that. I'm not sure I see the point in wider timber, but I can't see it would do any harm. Did the SE have any detail on this?

 

How have they tied old and new masonry together? I'm not very experienced, so don't take it from me, but I thought it was usual to have an expansion joint at such a join?

Think you should tell the brickies about the new invention called a trowel.  By the looks of they just throw their cement from about 6 foot away and call it a job done.

 

No insulation?

Brickies started so well..but slacking at end..agree will have to see if extra heavy straps will do. There is an ashlar wall which may take some of the slacking but not ideal. Not sure of any other solution?..you take eye off the ball for a day and this happens.

It's there, just covered in snots.
