i'm taking out a 2700mm wall in my timber framed house. just got my calc's back from my SE, which states for the lintel either, 2 No.63 x 195mm deep grade C24 timbers bolted together or a 127 x 76 x 13 UB steel beam. either to be supported at either end on 3 No. 50 x 72mm grade C24 studs bolted together.

firstly rough cost of either beam?

secondly do i basically 'add' the beam to the bottom of the first floor joist thus having a low point in the ceiling, or is there a way to have a flush ceiling without hanging a false ceiling?
