Hi all, this is my current kitchen set up with bath and toilet room pantry and outdoor built in shed.

I want to add tri fold door to the left in red and I am happy with what needs to be done there.

On the right I want to add a window to go above the new sink are however where the two outside walls are they are of different thickness?

Whay would be best for this?
Build up from the floor a new inner skin to bring it in line with the other half of the wall?
Or is there a lintel that will be okay to over hang and the inner skin and then board out below to bring the wall flush with plaster board etc etc

Any ideas?

Cheers

p.s. on mobile so please bare with spelling and reply time

Anyone got an input?

The easiest thing would be to span a long lintel over the window, with the right end bearing on that right hand external corner

its a party wall so I imagine that will pose problems?

What sort of roof is on it?

Mine is end terrace (4 houses) so I have a 3 sided pitched roof.
What I dont understand is the floor above sits on the outside wall across the whole of the back wall so why would the joist sit on two different thickness'es of wall.

I cant understand why they went to the effort of building it like that esspecially across 4 houses (I assume the others are the same)

One would think it eaiser to just dig 1 width fottings and lay the whole back wall in a go not a "2ft wall then 1ft wall then 2ft wall etc etc"
