Closing Off Area Beside Glazed Door

[mnodggs]

Hi All,

I have made a large opening at the rear of my property to put in a glazed large sliding door. In the image below the yellow box is an approximate size that the sliding door will occupy. I need to build up the area in the red box.

The sliding door will be aluclad, and the makeup of the exposed blockwork on the left is one layer of solid concrete block where the dpm is and then hollow blocks up until steelwork, although the steel is resting on one solid concrete block. I will be externally wrapping the entire property after the door has been installed.

What's my best bet to build up the area in red? Its not quite a full block wide, and trying to tie new block work into the existing hollow blocks seems like it will be a messy job. Is my best bet to put in some timber framing, fix this to the exposed blockwork on the left and allow the glazed sliding door to mount to that, with a bit of insulation board between the framing? This seems like the easiest option. If I went this route, what would I use to cover the external framing and insulation so it is flush with the external render so the external insulation can be easily applied.

Bonus Question:
The exterior of the steel beam is essentially the same as the interior seen below. What do I need to do here? Should I just prime the steel work, fill the gap with insulation board and allow the external wrapping to fix to that?

Why not get doors to fit , or add a glazed panel .?

I'm gonna hazard there's a run of kitchen cabinets running down the left hand wall ....

You are exactly right. The opening is that big on the left, because there was an existing window with that edge on the left.

Did the structural engineer specify a minimum return on that side for lateral stability.

No, what I am putting in doesn't need to be structural, It might just need to be strong enough for fixing one end of the fixed Aluclad pane

But you have removed something structural.

Brick walls on one elevation often need a certain amount of wall returned to act as a buttress.

Imagine a tall garden wall 8,0 high that just stops at each end, then imagine the same wall with a return if say 700mm - the return makes the wall rigid, especially against wind load.

I’ve no idea if it’s relevant in your case as I can’t see the rest of the building

Yes I see what you mean, the engineer just said there needed to be x amount of overlap for the steelwork into the brickwork, which is what was done.

He didn't specify that I need to rebuild for further structural support.
