knocking through chimney/fireplace/supporting wall(?)

Flurph

Hi all,


We are looking to buy a Victorian semi detached property (the ones with the long thin back end with small Kitchen and old scullery behind).
In some the kitchen has already been extended through to what would have been once a scullery. In many now it is a rear downstairs toilet.

The house we are thinking of buying it is actually a tiny kitchen where the sink and cooker etc is.

The wall separating the two has a chimney stack and fireplace where I assume the old range used to sit. None of the Victorian features which might make it a nice idea to possibly keep currently exist.
We plan on knocking the wall out creating a larger kitchen and likely putting in some French doors in the back wall leading out to the garden. I think the wall separating the two rooms is possibly a supporting wall and that the scullery itself is a really old extension but I am not certain.
I was wondering if someone had done similar with their similarly configured home and may know whether it is supporting and also how much works might cost in doing these works.


Thanks
