Wasn't expecting this wall....

[David Mcroft]

Hello all, first post so apologies if this has been answered before. I am a moderate DIYer and have opened up doorways in (non-structural) walls before, on this occasion once the plaster fell off it revealed a weird mix of timber and on-edge brick. It's a first floor dividing wall with a brick wall below but the floor joists run between the two. The bricks are pretty much all loose, some fell out with the plaster. My question is the doubled up vertical timbers, they run up into the loft and are toe-nailed into the roof beam, there are no other similar supports to the roof beams so do you think this is a one off intended to position the vertical timber and hence the wall or is there a possibility of these being structural to the roof? The vertical timbers are right in the middle of where I need the door

Its a structural stud wall. Use a suitable lintel or beam of some sort, and frame the opening in suitable timber too.

show us the roof construction, please, and indicate where this wall runs below.

Thanks for the replies, much appreciated. Should I be worried then that the wall to the left of the verticals is easy to move without too much force, might just be the lack of plaster although the horizontal timbers are not fastened to the vertical. Pic of roof attached, you can just about see the bricks of the wall at the bottom of the second image. If there is a risk that it is structural then I will get someone out to have look, just wanted to get an opinion first as I had not seen this kind of wall before, didn't expect it to have any structural issues with it sitting on top of the timber floor. Is there any merit in removing and replacing with a sturdy stud work wall?
Thanks again.

It's just a standard, brick-on-edge partition - almost always non-structural.
The studs are nailed to the purlin in the roof space to provide stability to the partition.
