I am in the process of preparing plans for an extension to my house. I would like to incorporate a green oak “cruck” frame within the kitchen and extending on upwards to give a vaulted ceiling within the bedroom above. I would like to fit the frame against the inner leaf of a blockwork cavity wall.
I was wondering whether there would be any problem with positioning the frame here i.e. would there likely to be much axial movement of the posts as the oak dries, which might cause problems with the blockwork internal skin adjacent to the post. How far would you suggest the posts should be set away from this skin?

Thanks Steve.
