Increasing ceiling/roof height on kitchen to allow for patio doors

I have a kitchen that has nothing on top, that has a very low ceiling/roof.
Half of the kitchen’s roof is normal, and around the middle there is a big drop, with the end height being about 1.40cm.
I would like to raise the ceiling/roof to be able to install patio doors and be able to see the landscape views from the kitchen.
How much could this cost and would it be worth it? Is it a lengthy job?
Thanks!

"Hi there, as others have said hard to tell without seeing pictures but you may be talking about a hipped roof and you want to create a gable?
Alternatively if you mean the roof slopes towards the outside wall/back garden - you may be able to create small dormer overhang to enable doors underneath

Hard to give a ball park figure as so many variables!"

"It all depends on why the ceiling is so low. Is it a false ceiling or does it have beams for upper floor inside or possibly the staircase? Until the ceiling is removed to expose what’s underneath it would only be possible to tell from investigating"

"Would need to know what your current roof is. Is it flat pitched
It’s a job that would really need looking at to price correctly
However if it’s what I think it is its not a long process just very messy and around £3 to 5 thousand but it’s a guess at this time"

"Hi it sounds like it will be possible hard to tell without seeing it or a picture but from what you’ve explained can’t see any problem. It’s not a big job neither would it take to long.
Thanks Carmine"
