Hi all,
I am building an extension, and am pondering how to fix the door into the door opening. Its a 300mm cavity wall, with a 90mm deep door frame recessed by 50mm to match the doors on the rest of the house. A quick diagram is here:

manufacturers of the door say that I must put frame fixings through the thinnest part of the frame, but that would be too close to the inner edge of the blockwork to be sensible. I seem to recall coming across a photo of something I think was called a `toothed return'. Rather than putting a full height return off the leaf into the cavity, just a few blocks are returned where the frame is to be fixed:

this a sensible thing to do though? I can't remember where I saw the photo, and whether there were any things to beware of if doing it, so any advice or alternative suggestions would be welcome. It might not even be called a toothed return, which may be why I can't find anything about it again now.thanks,
dan.
