Hi Shawn:

Nice to see more details.

The vertical ridge supports I suggested would be convenient w/ posts already there at midspan of the building. Of course the existing posts need to be sound enough / large enough and on footings capable of handling the added compression.

Will's advice on getting some professional opinion is wise. Though there's nothing wrong w/ offering up suggestions here--many forum members have a lot of experience--there of course could be more issues at play.

And I also see a lot of mixed hewn and sawn stock here in Maine. I agree that it's a length issue. Most mills could only handle about 24' of length, which is why the longer members were typically still hewn.


And no dovetailed/wedged tenons on those tie beams? That really is a poor design. Not much stopping any withdrawal.

Good luck; keep us "posted."
