cutting door in block construction at a building corner

Posted by tr on May 16, 2007, 2:56 pm

I need to cut a new 32" exterior door in to my masonry block home.
the location of this will be right at the corner junction of two
exterior walls. The type block in this area is the shorter 4"
height...not the typical 8 or 9 inch high hollow core block. I have
a
flat roof and this door way will be about 2.0 feet below the roof
line.

Can I cut flush with the perpendicular exterior block wall and mount
my double 2x8 side framing flush with the perpendicular corner
wall...or
should I cut so there is at least some of the return wall stub left
in
the corner ?

Also...do I need to support the opening during cutting will some
type
of post/ceiling support..?..or will the block construction be strong
enough to cut out
the 32" x 90" or so opening and install the reinforced sides (double
2x8's each side) and
header (5 2x10's) without a temporary support system ?

Do your codes allow that? I believe here in the UK you aren't allowed to put
a door right at the junction (buttressing issue).
