Chimney breast removal/loft conversion

[Raibeart]

We have a 1930s semi in Surrey, UK and are looking to do a loft conversion.

 

If possible we want to remove the chimney breast in the loft space to provide greater width to the new master bedroom.

 

We have received these plans from the structural engineer with a set up we’ve never seen before - see attachment.

 

In summary, the chimney breast has been removed, to new ceiling level with the stack supported with a steel beam and then the redundant chimney flue/pots filled with a steel column and concrete.

 

As said, we have not seen this before and would like to check whether it is acceptable to building control.

 

Is this the best way or are there alternatives?

 

Thanks in advance for any replies and comments

Never seen that approach either. Wouldn't a steel plate the size of the bit of stack being removed sat on B1 and B2 do the job with the pots capped.

Hello Raibeart,

 

Just wondering if you managed to remove your chimney breast in the loft as part of your loft conversion.

 

Did the structural plans get approved by building control?

 

I am also in a similar situation (1930s 3 bed semi detached) and in process of getting planning approval and building regulations for a hip to gable loft conversion. I too would like to remove the chimney breast in the loft but not sure if it is feasible or even allowed.
