Undercloaking with counter battens?

[Iaindj]

I'm shortly erecting a gazebo with open gable ends. The roof will have T&G over the rafters, then counter battens, membrane, tile battens then clay tiles.

I don't want a barge board at the gable as that'd hide the oak frame.

Is it possible to have the undercloak board under the counter battens or will that make far too big a gap to mortar..?

Am I stuck with a barge board or oak trim to cover the gap if the undercloak has to go over the counter battens?

Thanks for any help/advice

Would a continuous dry verge help?

Thanks, but I don't like the look of the plastic on a an oak frame - at least the systems I've seen.

I have seen one possible solution of using oak boards as a decorative to hide the counter batten

) then I could run the cement board on top of this so only have the usual single batten space..?

A deeper verge fillet has much more risk of cracking, and TBH it would not look right anyway.

You'll need to hide the section below the undercloak with a cover piece, and I can't see why this could not be made to look like part of the frame if the gable is to be left open

Thanks. That's the plan, use an oak plank to create a detail that hides the country batten and also supports the cement board.
