Lintels overhanging a newly made door way?
Tony Graham
We stay in a semi-detached with up and downstairs.
We had a doorway knocked into an outside supporting wall so we could access
an already in place extension. It was more convenient with this layout.
We submitted plans for the work but for the life of me I can't find them and
the building clerk is coming next week to inspect it (hopefully grant a
certificate)
The work was carried out 2 years ago so its all very hazy the actual
details.
What I'm looking to know is, is there a guide on how much the concrete
lintel should overhang the brickwork below? Given it is the ground floor of
the outside wall.
They told me just to take pictures at the time as that should suffice.
Cheers.

supported on brickwork either side of the opening? How wide is the
opening - is it just single door size?
For a single door width, 150mm each end should be sufficient - so the
overall length of the lintel should be at least 300mm greater than the
width of the opening.

Cheers Roger. Yes sorry the overhang that supports the brickwork either
side of the door opening.
I managed to find the plans and like you say it should be min 150mm bearing
each side.
I've also found the pictures with measurements and it doesn't bode well.
The lintel measures 1040mm and the door opening measures 820mm.
So I make it 80mm short!!! It looks to be sitting at 120mm overhang at one
side and 100mm at the other!.
Anyone know how picky these guys are?
In my favour it was done in 2007 and there has been no cracks etc above it
plus the lintel was meant to be a Robeslee 100mm x 70mm and it looks more
like a 150mm x 70mm if that makes a difference?

How much is it supporting?
I have one lintel overhanging on one end by maybe 2.5-3" !
No it wasn't one of mine - and it is holding up 4-5 courses of brick for 3'

Its the ground floor of an outside wall so I suppose it is holding up the
whole of the gable end!!!!

It's probably holding up 2 dozen bricks at the most.
The brickwork above is supported by the brickwork on either side of the
opening, by deflection

More like a triangular section of brickwork over the opening (the
interlocking of the bricks or blocks tends to share the load sideways).
It's not going to fall off, for a doorway sized lintel. As to whether the
BCO will like it is another matter. This would be an opportune moment to be
of few words... But see what others think - personally I wouldn't be too
worried if the wall it is bearing on is of good construction.

For a door sized gap, it won't actually be carrying much - if you took
it out you would leave just a triangle of bricks above the opening
unsupported.

Nonsense. It's holding up the triangle of brickwork above the doorway
that's all. Cills have far more weight on them.

I'd expect the BCO to be fine with that. http://www.buildingdesign.co.uk/facil-group4/naylor-lintels/
suggests a standard bearing of 100mm either side on an opening of less
than 1m, although it would depend a bit on the strength of the
brickwork it's sitting on.

Unlikely, the bricks would fall away in an inverted triangle above it until
they reached the point where the outside walls supported the rest. The angle
is about 45 degrees.
Its more of a problem as the lintel could be supporting one or more
rafters/trusses (not likely if its on the ground floor) or joists depending
on how they run.

Thanks guys. The BCO arrived and granted the certificate.
He just had a quick squint of the "blurry" pictures with the measuring tape
against the lintels.
Thanks again.
