300mm wide cavity brickwork wall supported on 220mm brickwork

[2kwiggle]

The architect wants a wall that has a recess at between two slab levels. The bottom meter high of the wall is a 300mm thick cavity brickwork wall, the middle meter high is a 220mm brickwork wall and the top meter is 300mm thick cavity wall again.

I am trying to figure out the best way to support the top, wider wall. Any suggestions would be appreciated.

There are also cases where a window opening, 1.1m wide and 1m high is within the 220mm brickwork wall which also needs support.

If there is a lot of repetition, possibly consider a purpose made 300 wide precast lintel/beam for the top portion.
If there is not a lot of repetition then ask the architect if you can have 330 brickwork instead of a 300 cavity wall. This would then be easy to resolve.

You are allowed to corbel brick in and out as long as it meets certain criteria. Look at BIA Tech Note 36A
