Wall stability without a return

[John6767]

Hi

Is the 2.1m external lobby/porch wall stable without a standard 3-brick (665m) return?

'Approved Document A' doesn't have a minimum wall length before a return/buttress is required.

If not stable, what are the options?
A 300 x X mm brick pier at the bottom corner, bed reinforcement/mesh, SE masonry wall panel design, or else?

Does it have a roof above?

Yes of course, will have a sloped roof on top attached to the house front.

If it has a roof it will provide a degree of stability, but might a narrow brick pier work lose over time with a wide, heavy door banging shut?
Your diagram isn't very clear, some dimensions would help.

Exactly, my concern is the wide door/window.

I made another diagram (sorry for the quality as I was in a rush), hopefully it has more info, let me know if you need some specific detail.

You need to get the 2100 long wall checked as a panel wall, bonded at one end, and simply-supported top and bottom, with one free edge.

If it was shown not to work, a coated steel post within the cavity might be necessary, with a plate bolted to the concrete foundation, and fixed to a wall plate or other part of the roof at the top.

With a 300 thick wall showing its edge, your bricklayer will need to do some careful cutting.

A quick check showed the panel capable of taking the lateral load, even with being conservatives, utilisation is <50%.

You mean a windpost? I didn't mention it as an option due to its cost and lead time. Had a look now on ladder type reinforcement, not a cheap option as well! The mesh is not as effective structurally I suppose.

Despite the above, what a cost effective measure could still be done here to strengthen the wall for the worst days?
