Thanks for continued support!

I assume you are trying to avoid having the beam projecting down into the
room.

Exactly


Put the beam under the rafters ..............


Do you mean joists??


Do you actually need a beam, if there is no load on the joists?

I certainly need something. There is a wall running across the room at the
point where I intend to install the beam. At this point the joists are cut
and overlapped with the overlap sat on top if the wall, presumably to keep
the beam span and therefore the section size down. The joist spans are
approx 3.5m and 1.5m.
