Eaves boarding - how would you have done it?

[gluecifer]

What do you think looks best, on the long sides of the extension as it appears in the picture?

Either board the eaves and attach boards from the outer eaves board all the way in towards the panel (blue lines) or nail along the underside of the roof truss rule slanting inward-upward (solid green line).

I wonder because the boarding will be barely 40cm from the panel out to the outer eaves board, which in my imagination seems quite wide aesthetically. It's hard to explain... do you understand what I mean?

on my house it is like the blue-striped line but about 0.5m and it looks completely okay I think.

here's what it looks like at my cabin, similar to your blue line.. sorry for the cropped image, but the 100kb limit put a bit of a damper on things for me.

Looks good Marko - I followed your lead and now we're using a base panel 21x120 and I'm installing it like you did. But since it is tongued and grooved and you push them together, the air holes will be at the very edge, I think.

Otherwise, it is probably quite common that you just nail regular boards with a ventilation gap in between. Don't forget insect nets, regardless of where you place the ventilation.

Thank you gluecifer. As the home tinkerer says, use boards without tongue and groove and leave a gap between the boards for ventilation of the attic, that's how I've done it.
