Sunday! and me and Adam are in as we don't have a life.
We are cladding this one in western red cedar, T&G, 18mm x 83mm. This is IMO the best cedar around and ive tried it from other suppliers. Duffield timber in Ripon supply us and id highly recommend you have a chat with Conner.
There's a window trim detail and top bead.
We have also oiled it, even though I cannot pronounce the manufacturer or the word architrave, but if you can see past that you may enjoy the video.
Best wishes and stay safe!
