That, sir, is not a bloody mess!

I'll pop up a quick snap of my kitchen this evening...

i did the whole inserting cooker into the chimney breast, never ever again. the amount of soot was unbeilevable. decided to keep the structure though as didn't want to face removing it all the way up the house.



3 weeks after i got the cooker in, the mrs became pregnant again and we had to bloody move as its only a 2 up 2 down and we have one child already.

Totally unqualified view but all that weight on those london brackets makes me nervous yikes That looks like a metre span supported by two smallish brackets?

What's the view from those that know?

Not trying to be a dick here either.

I agree. I'd have wanted something much more substantial!

Mine were done on those brackets all approved by the building inspector, I questioned it and was told the wall supports the chimney breast not the brackets, they are just holding the bottom few bricks up.

Must be ok.

in a nutshell - this. the builder made contact with a bloke at building control, explained the quality of the brickwork, thickness of the wall and the circumstances of the neighbouring property, he said if that is all correct then the brackets will suffice (subject to inspection/sign off). so we will see.

the builder said he has been to properties where a removal was done in similar circumstances and no support was installed at all, in the past!

and before anyone asks, yes I did a party wall notice, yes they knew about the supports and yes they agreed to the work!

The support of a chimney is, ime, getting a bit hit and miss with BControl. Corbelling should be sufficient - and indeed used for many centuries without issue - but is unacceptable. Other departments allow London Brackets and concrete lintels. Others insist on steels and plate. Because of this, irregardless of what is specified, the Professional is left exposed to either under or over specifying.

local building control chap seemed (fairly) relaxed about it I think.

back in hertfordshire where my parents live, they were flatly told (a number of years ago) that the brackets would not be acceptable under any circumstances

I get the gallows brackets will hold the sides of the chimney but what's holding the 'face' brickwork up? Seems to me there's an inverted 'v' of brickwork hanging in mid-air. Is there a steel plate sat on top of the gallows brackets, like so?

I've done a varity of versions. The above seems reasonable. As a variation, I've used concrete lintels in lieu of the plate and angle. Nowadays, I either ask the S Eng to give me the design they are happy to go to BC with. Or, leave a Prov Sum and speak to BC when the time comes to do the work to see what they want to see.

Even in the same Council, different teams insist on diffrerent solutions. Very frustrating for such a simple alteration.
