This is a timber frame, but no timber frame specialist involved, I did the sketch myself. I am on a very low budget and have been and will continue to watch as many youtube videos and read as much as possible to learn. Would you say I really should get specialists involved? I wont be having an external masonry skin, just some sort of cladding.
The sketch does show a stud wall and OSB sheathing, there is also a lintel/door header which is above the door, but details of the lintel i have yet to finalise (was planning on more in depth research before this part).
