Birdmouth in middle of rafter

[david2012]

Hello folks.

I’m having a lift conversion done. On one side the carpenter has cut birdsmouth notches into the middle of the rafters to fit a stud wall. Does this look ok, to me it seems a bit pointless putting up a huge piece of wood to suspend the roof and then cutting a notch into it.

Most be some whopping span on those rafters

It might be a structural requirement (restraint?) as the floor joists go in the opposite direction to the rafters?

Is there a load bearing wall under the studs? The base plate seems to be set way down so there may be support provided by the studwork but those are huge rafters so not obvious quite what's going on.

For peace of mind, I would get confirmation from your designer before you go any further
