Chimneys & Fireplaces Question
Is it possible to put bricks in two layers while constructing a chimney?
I would like to know if it can influence the overall design of the chimney.
Thanks, BJD, that actually is what I meant, I should have been more specific, sorry for that.
Anyway, thank you very much for your answer, I just never used to build a chimney before.
I have been in the trade just over 40yr, so I do know a bit, but I cant understand your question.
If you mean laying 2 bricks, 1 on top of the other, going in courses, up full height of stack, then no, they should be half bonded.
This is only a guess at your question, maybe re,edit your question.

Assuming you are referring to the wall thickness it is possible to build a chimney in 9" thick brickwork as long as the plan size of the chimney is sufficient to allow for the width of the wall and the space required for the flue opening.
You would also need to be sure that the inside leaf of bricks has a suitable support below. It would be best if it was this thickness for the whole height of the chimney breast.
