It's the extension faced with glass or encapsulated?

@Lorenz I've been working in the oak framing industry for the last 15years. 11year with a leading company in this sector. The majority of oak frames now are wrapped in a encapsulation envelope. But they still do the traditional builds which are alot more work but look the nuts and as you said above what you see inside you can also see outside. Obviously the traditional build comes with alot more problems with water ingress etc. The other way people do it is to have the oak frame built, encapsulate it and rather than clad it, have a screen of traditional looking oak on the outet face of the encapsulation panels. This way you get the best of both and piece of mind that if the water gets in it will fall into a "cavity". Obviously Two major factors with this way...1.You need deep pockets and 2.The frame you see inside is different to what you'd see on the outside! All the best ?

I was going to install eaves vents at the top. @TonyT Although there is vents under the first corse of slates so thought that would suffice.

I think some plastic pipe to extend is the way forward @TonyT Good stuff

Okay. Don't these need fitting towards the bottom of the "cavity"? As the photos show the wall is block plus two corse wide in the bottom?. Thanks for suggestion @TonyT much appreciated

Hi all. Not far off starting a conversion on our garage. Was built approx 18months ago. Single block skin with render finish. The plan is to stud out inside, rigid insulation board between studs then a sheet of rigid over the face, then batten (service void) then plasterboard. Obviously taping and sealing for vcl etc. What I'd like to know is what's the best idea for ventilation within the cavity? We have vents ontop of the fascia, underneath the first corse of slates but that's it. Would this suffice? Or is there any ideas? Or do I leave as it it... As you can see the rear wall is retaining some of the garden at the moment but will be tanked etc once the new drainage line etc is put it. There is no signs of damp inside etc either. Much appreciated
