Loft/Chimney Stack/Structural engineer

[davgar]

Removing chimney breasts in a semi-detached house
Plan was to use a steel beam to support stack.
Unfortunately discovered the front wall is higher than the central loadbearing wall.
Is the following type of approach possible?

[davgar]

neighbour still requires his chimney.
is it possible to remove my half of stack?

[davgar]

will get that investigated.
externally stack looks like this.

[davgar]

not allowed by building control

[davgar]

SE thinks the approach from the drawing is fine.
I would have thought removing one half of stack is easier but builder doesnt think so.

Building control already said they dont like gallows bracket unless chimney is on ridge

bob - please can you show me the link

many thanks

gallows are ok if next door hasnt already got one, they need to push against something.

LABC have a standard gallows bracket detail that is type approved.

my builder doesnt fancy slicing it in 2.

i had a thought - is it possible to remove stack completely; retile roof and provide for neighbour something like this.
is changing from a brick to a modern flue even possible
(subject to neighbours approval )

need to check - assume gas - living flame
