The local builder doing some work for me has opened up the rear wall of a single floored house and used 4 floor joists bolted together to hold up the wall above it which has a right angled triangle of double brick work above it forming the roof slope. One end of the beam sits on the side wall at roof gutter level, the other end sits under the apex on the party wall, the brickwork above at the party wall end is about 1.6m high. Span is about 2.5m . Does the supporting joist sound ok, he tells me a structural engineer did the calculations and its to be encased in plaster board.
