That really looks excessively clean and tidy!

:-)

Where is the RSJ that should be supporting the ridge ?. Assuming
this is a loft or dormer conversion ?.

Er, it's that 9x3" bloody big beam held up by a column at each end.

The conversion was done in ancient history before anyone cared much (1970s).

I've done some fag packet calcs and even with maximum SE England snow
loading allowed for, the total load on that beam is 1200kg-force or
600kg-f per column. The original 3" column on the left was a bit slim,
which is why we tapped in an extra 4x4" whose max load ability is around
2000kg-f. All columns bear down onto load bearing brick walls.

So I'm not unhappy.
