I am helping a friend planning a barn conversion. It is 1850s and has solid stone walls with brick quions, the walls are approx 450mm thick. Its a long thin rectangle 6m by approx 25m
It has a Mono-pitch about 20 deg and as the span is about 6m and as it will be self built I had thought JJI type joists will work well requiring no purlin and being easy to install.
The joists for that span will be about 300mm deep but this is going to leave a very deep fascia which on a traditional stone building will look awful.
Ideally to retain the traditional look there would be a flush eave with no fascia but im not sure how to detail this given the solid stone walls and the deep joists?
Initially i had thought of building a soldier course of reclaimed brick on the exterior, which would look ok and fit with the quoins, and then leaving the wall plate low on the inside but concerned about damp proofing it.
Anyone any experience of this type of detail or any ideas? I know very little about roofing other than the obvious so apologies if this is rudimentary.
Thanks
